The illustration on the next page shows all the equipment you will need to set

up your computer and begin using it. Place your equipment on a sturdy, flat

surface near a grounded wall outlet. Before following the setup instructions in

this chapter, you may want to read “Arranging Your Office” in Appendix A

(in the section on health-related information) for tips on adjusting your work

furniture so that you’re comfortable when using the computer.

Plugging in the computer

Before you plug your Macintosh into a wall socket, carefully read all the

setup instructions in this chapter. Then, before you connect anything to your

Macintosh, follow the instructions in this section to plug it in. The plug

grounds the computer and protects it from electrical damage while you are

setting up.

When you are ready to begin, follow these steps:

1Place the computer where you want it.

Carry the computer with its screen facing you. Most of its weight is near the

screen. Lift with your knees, not your back.

Getting Started

2Plug the socket end of the power cord into the recessed power plug (marked with the

symbol

≤

) on the back of the computer.

Make sure at least one end of the power cord is within easy reach so that you

can unplug the computer when you need to.

IMPORTANT

To protect both yourself and the computer from electrical hazards,

the computer should remain turned off until you are finished connecting its

parts. Check the power switch at the back of the computer. Make sure that the

side of the switch marked with the j symbol is pressed in.

3Plug the other end of the power cord into a three-hole grounded outlet or power strip.

Installing an expansion card

If you purchased an expansion card for your Macintosh, install it now. (See

Appendix B, “Installing Expansion Cards and Adding Memory,” for

instructions.) If you don’t have an expansion card, continue with the next

section, “Connecting the Mouse and Keyboard.”

WARNING

This equipment is intended to be electrically grounded. Your

Macintosh is equipped with a three-wire grounding plug—a plug that

has a third (grounding) pin. This plug will fit only a grounded AC

outlet. This is a safety feature. If you are unable to insert the plug into

the outlet, contact a licensed electrician to replace the outlet with a

properly grounded outlet. Do not defeat the purpose of the grounding

plug!

Connecting the mouse and keyboard

The way you connect the mouse and keyboard depends on whether the

keyboard has a built-in cable or a separate cable.

Connecting a keyboard with a built-in cable

1Plug the mouse cable into the recessed port on the back of the keyboard.

The plug and the port are marked with the ◊icon (symbol). The positions of

the port and icon on your keyboard may be different from those pictured.

By the way: A port marked with the ◊icon is called an Apple Desktop Bus

(ADB) port.

This cable plugs into the Apple Desktop Bus (ADB) port,

marked with the

◊

icon, on the back of the computer.

Plug the mouse into the recessed port on

the keyboard. The flat part of the plug should

be pointing down, as shown here.

Tips for using Macintosh Guide

Here are a few tips for using Macintosh Guide effectively:

mMacintosh Guide is available only when you are in the Finder—the

desktop area where you can see the icons of disks, folders, and files.

(Other programs may also have help available in the Guide menu,

however.) If you don’t see Macintosh Guide in the Guide menu, pull

down the Application menu (to the right of the Guide menu) and

choose Finder.

mFollow the steps when you’re instructed to; don’t skip ahead or read

ahead. That way the computer can check to make sure you’ve done a

step correctly.

mUnlike most windows, the Macintosh Guide window stays in front of

other windows on the screen so that your instructions are never

covered. If you need to move the Guide window out of the way, drag

it by the title bar at the top of the window.

You can also move the window out of the way by clicking the zoom

box. Click the box once to shrink the window; click it a second time

to expand the window to its original size.

mIf you need more information about an instruction or a term, click the

button labeled “Huh?” to get further explanation. (The “Huh?” button

is dimmed when no additional information is available.)

mIf you want to return to the main Macintosh Guide window, click the

Top i c s button in the lower-left corner of the Guide window.

mWhen you’re finished using Macintosh Guide, click the close box in

the upper-left corner of the window.

Identifying objects on the screen

Sometimes you’ll see an unfamiliar item on the screen and ask yourself,

“What’s that?” You can get an answer by using a Macintosh feature known as

Balloon Help.

Balloon Help explains the function of icons, menus, commands, and other

items on the Macintosh screen in balloons like those you see in comic strips.

Follow these steps to use Balloon Help:

1Pull down the Guide menu (marked with the

icon) and choose Show Balloons.

2Point to any object on the screen that you want to identify.

A balloon appears next to the object. In the following illustration, for

example, pointing to the Trash displays a balloon that explains how to use the

Trash to throw items away.

Although balloons appear next to items when you point to them, the way

you work does not change; you can still select icons, choose commands, and

so on.

3When you’re finished using Balloon Help, choose Hide Balloons from the Guide menu.

30 Chapter 2

Connecting to an Ethernet network

If your computer has an optional Ethernet card, you can connect your

Macintosh to any standard high-speed Ethernet network. You can connect

your Macintosh to an existing Ethernet network that uses thin coaxial cables,

10BASE-T twisted pair cables, thick coaxial cables, or other standard cables.

You may need to purchase an appropriate Apple Ethernet media adapter or

other compatible media adapter to connect your Macintosh to a network.

(Consult the service and support information that came with your computer

for instructions on how to contact an Apple-authorized service provider or

Apple for more information on Apple Ethernet media adapters.)

To use Ethernet, you need to change the network connection in the Network

control panel. (For instructions on how to select a network connection and

other information about using your Macintosh on a network, see the

“Networks & Telecommunications” or “Sharing Files” topic (depending on

the version of system software you are using) of Macintosh Guide, available in

the Guide (h) menu.

IMPORTANT

Your Macintosh supports EtherTalk Phase 2 (AppleTalk Phase 2

Protocols for Ethernet networks) and TCP/IP (via MacTCP software).

Non-Apple products that you can use to communicate over Ethernet using

protocols are also available. Your Macintosh does not support EtherTalk

Phase 1 (AppleTalk Phase 1 protocols for Ethernet networks).

CAUTION

The use of an Ethernet card will make your Macintosh a Class

A computing device, according to FCC regulations.

Expanding Your Computer and Using Special Features

Connecting a second monitor for video mirroring

You can connect a second, external monitor to your computer to display the

same images that are on the computer’s built-in monitor. Displaying your

computer’s images on a second monitor, called video mirroring, is useful

for presentations.

If you want to use video mirroring, you need an Apple External Video

Connector (available from your retailer) with an external monitor attached.

(If your computer doesn’t have this connector, you can install one.)

The external monitor must use the same resolution and timing as the built-in

monitor. If you want to display your built-in monitor’s images on a standard

TV or record them using a VCR, you’ll need the Apple Presentation System,

which adds these capabilities when used with the external video connector

kit. The Apple External Video Connector kit and the Apple Presentation

System are available for purchase from computer stores. (Some computers

come with the Apple External Video Connector kit and/or the Apple

Presentation System.)

For more information about the monitors that you can connect to your

computer for video mirroring, see Appendix D.

Apple external video connector installed

40 Chapter 3

Connecting external SCSI devices

Your computer has a port for connecting devices that use the Small Computer

System Interface (SCSI, pronounced “skuh-zee”). The SCSI port permits

high-speed communication between the computer and the device. The SCSI

icon appears below the port on the computer’s back panel.

You can connect SCSI devices to the SCSI port in a chain. SCSI devices

commonly used with the Macintosh include hard disk drives, CD-ROM

drives, scanners, some printers, and tape or cartridge backup drives.

Your Macintosh can support a chain of up to six SCSI devices. The internal

CD-ROM drive (if you have one) is the first device in the chain. Therefore,

you can attach up to five external SCSI devices to your computer. (If you do

not have an internal SCSI device installed, you can attach up to six external

SCSI devices to your computer.) The first external device plugs into the SCSI

port; the second device plugs into the first device, and so on. All SCSI devices

connected to this chain must have their own unique ID number.

IMPORTANT

The next sections, “Before You Connect a Device” and

“Connecting a SCSI Device,” contain general instructions for attaching SCSI

devices to your computer. Be sure also to follow the specific instructions that

came with your external hard disk drive or other SCSI device when

connecting the device to your Macintosh.

Before you connect a SCSI device to your Macintosh, be sure to complete

these tasks:

mMake sure each SCSI device connected to your Macintosh has its own,

unique ID number from 1 to 6, but not 3 (the internal CD-ROM drive is

device 3). See the instructions that came with each SCSI device for

information on checking and setting its SCSI ID number.

IMPORTANT

If you use two or more devices attached to the same SCSI

interface with the same ID number, your equipment could malfunction and

you could lose data as a result.

mMake sure you have the appropriate cable for attaching the SCSI device to

your Macintosh.

If the device is the first or only one you’re connecting, use a SCSI system

cable to connect it to the computer’s SCSI port:

If the device is not the first one, use a SCSI peripheral interface cable to

connect it to the last device in the chain:

SCSI peripheral interface cable

SCSI system cable

42 Chapter 3

IMPORTANT

The total length of the cables in a SCSI chain should not exceed

6 meters (20 feet). SCSI cables must have a 110-ohm impedance. For best

results, use SCSI cables manufactured by Apple Computer.

mMake sure that the last (or only) device in the SCSI chain has a terminator.

Make sure that no other external SCSI device has a terminator.

To ensure accurate transmission of information, a terminator must be at

each end of a SCSI chain. Your internal hard disk, which is the first device

in the chain, has a built-in terminator.

Some external SCSI devices from manufacturers other than Apple have

built-in terminators. (Check the information that came with the device.) If

the device at the end of the SCSI chain does not have a built-in terminator,

you need to attach an external terminator.

If your SCSI device has a built-in terminator, use it as your last device in the

chain. (Or, you may have your Apple-authorized service provider remove any

extra built-in terminators.) You can attach or remove external terminators

yourself.

Expanding Your Computer and Using Special Features

Connecting a SCSI device

Use these general instructions in conjunction with the instructions that came

with your SCSI device:

1Turn off your Macintosh.

2Make sure the SCSI device is switched off.

3Use a SCSI cable to connect the device either to the computer’s SCSI port or to the last

SCSI device already in the chain.

4Turn on all devices in your SCSI chain.

IMPORTANT

Always turn on any external SCSI devices connected to your

Macintosh before turning on the computer itself. Otherwise, your computer

won’t be able to recognize that the SCSI devices are connected to it and your

computer may not be able to start.

5Install any necessary device drivers (software that makes a device work with your

computer).

Drivers needed for a SCSI device usually come on a floppy disk with the

device. (If no drivers come with the device, contact the device manufacturer.)

Note: If you experience problems after connecting a SCSI device, see the

troubleshooting information in Chapter 6 for possible solutions.

WARNING

Do not connect or disconnect any device while the device or

your Macintosh is turned on. Doing so could damage the device, your

computer, or both.

44 Chapter 3

Your computer has several application programs already installed, as well as

some programs that you must install before you can use them. The programs

that come with your computer include

mAppleScript, which allows you to automate any actions you perform

repeatedly on your Macintosh

mPowerTalk, which provides built-in mail and collaboration services

mQuickDraw GX, which gives your computer more powerful printing

capabilities

mApple Video Player, which you use to watch video or TV on your computer

Yo u’ ll find most of these programs (and others) in the Apple Extras folder on

your hard disk. To find out if a program needs to be installed, look inside the

program’s folder for an icon labeled Installer. If you find an Installer icon and

want to use that program, double-click the Installer and follow the

instructions on the screen.

You may want to experiment with AppleScript, one of the programs on your

hard disk. With AppleScript you can automate tasks in the Finder and other

scriptable programs (programs that support AppleScript). Instructions for

using AppleScript are also included in the AppleScript folder.

With Apple Video Player and a video input card, you can watch video on your

computer. With Apple Video Player, a video input card, and a TV tuner card,

you can watch video and TV. For instructions on using Apple Video Player,

open Apple Video Player and then choose Apple Video Player Guide from the

Guide (h) menu.

Read this chapter for information on

installing and using application

programs with your computer.

4Installing and Using Application Programs

Installing application programs

Yo u’ ll probably want to buy and install additional application programs. See

the manuals you receive with your programs for instructions on installing and

using them.

If you have questions about installing and using an application program, refer

to Macintosh Guide, available in the Guide (h) menu, and the Read Me files

for the program. (Read Me files are text files that contain additional

information about application programs. They are usually found on the first

installation disk, as well as inside the program’s folder.)

In most cases, you’ll install an application program on your internal hard disk

from floppy disks that contain the program. The following illustration shows

how to insert a floppy disk in your computer’s disk drive.

For instructions on how to eject floppy disks, see the “Disks” topic area of

Macintosh Guide, available in the Guide (h) menu.

Insert the floppy disk, metal

end first, into the floppy disk

drive of your computer.

46 Chapter 4

Sometimes, you’ll install an application program on your internal hard disk

from a CD-ROM disc that contains the program. The following illustration

shows how to insert a CD-ROM disc into your computer’s CD-ROM drive,

the disc lying flat with the label side up.

For instructions on how to eject CD-ROM discs, see “Ejecting a CD-ROM

Disc” in Chapter 5.

To use your programs most effectively, follow these guidelines:

mTo avoid installation problems, turn off virus-detection programs before

you install any software.

mPut only one copy of each program on your hard disk. Having more than

one copy can cause errors.

mWhenever you copy a program disk to your hard disk, be careful not to

copy a System Folder. Always check to see what you’ve copied, and drag

any extra System Folders to the Trash.

mIf a program malfunctions consistently, try installing a fresh copy. If that

doesn’t help, find out from the software manufacturer whether your version

of the program is compatible with the system software you’re using.

Installing and Using Application Programs

Working with several programs at a time

You can open as many application programs and desk accessories as your

computer’s memory allows.

All open programs are listed in the Application menu at the right end of the

menu bar. The name of the active program (the one you’re using right now)

has a checkmark next to it, and its icon appears in the menu bar.

Finding out which programs are open

If you have several programs and windows open, you can find out which

program is active and which other programs are open by pulling down the

Application menu.

Switching programs

You can switch to another open program or desk accessory by choosing its

name from the Application menu.

If a program’s icon is dimmed in the menu, that means its windows are

hidden. Choosing the program from the Application menu displays its

windows.

You can also switch to another program by clicking in a window that belongs

to an open program, or by double-clicking a program icon (or the icon of a

document that was created with the program).

48 Chapter 4

program.

Hiding and showing windows on the desktop

You can hide all windows except those of the active program by choosing

Hide Others from the Application menu.

The other programs remain open even though their windows are hidden.

When you switch to another program, its windows become visible again.

If you want to see all the open windows, choose Show All from the

Application menu.

Backing up your files

Making backup copies of important files is good protection against possible

damage to the originals.

mYou can back up files stored on your hard disk by copying them to

floppy disks.

mYou can back up an entire floppy disk by copying it to another floppy disk,

or to a hard disk.

mIf a file is too large to fit onto a single floppy disk, you will need to use a

commercial backup program to copy the file onto multiple floppy disks.

mYou can use a commercial backup program to copy new and changed files

from a hard disk to another hard disk, to a tape drive, or to a series of

floppy disks.

mIf your computer is on a network, you can back up files by copying them to

a shared disk on the network.

Using Power Macintosh application programs

Your Macintosh is compatible with most application programs intended for

use with Macintosh computers. But certain programs are designed especially

for Power Macintosh computers. (These are sometimes called “native”

applications.) You’ll find that these programs take best advantage of your

computer’s speed.

Installing and Using Application Programs

Special memory requirements

Some Power Macintosh programs may be slightly larger than other programs

and may take up more memory. If you find that you are running out of

memory when you use your Power Macintosh programs, you can use space

on your computer’s hard disk as additional memory. For instructions on how

to use hard disk space as memory, see the “Memory” topic area of Macintosh

Guide, available in the Guide (h) menu.

You can also add more memory to your computer, as described in “Installing

Memory (DRAM SIMMs)” in Appendix B.

Shared libraries

Power Macintosh programs use special files called shared libraries. These files

help the programs to run more efficiently, and can be used by more than one

Power Macintosh program simultaneously. Any necessary shared libraries are

installed automatically in the System Folder when you install Power

Macintosh programs.

If one of these programs requires a shared library and there is not enough

memory available for the shared library, you’ll see a message that the program

could not be opened because of insufficient system memory. If this happens,

see the “Memory” topic area of Macintosh Guide, available in the Guide (h)

menu, for instructions on turning on virtual memory.

If a required shared library is missing, you’ll see a message that the program

could not be opened because the shared library could not be found. If this

happens, follow the directions that came with your program to reinstall the

program. If the shared library is still missing, contact the program’s

manufacturer for assistance.

Using older Macintosh programs

If you experience problems using an older Macintosh program, it may be

incompatible with your Power Macintosh. You may be able to use your older

program if you change the Modern Memory Manager setting in your

Memory control panel. For detailed instructions on using older programs

with your Macintosh, see the “Working with Programs” topic area of

Macintosh Guide, available in the Guide (h) menu.

50 Chapter 4

Read this chapter for information on using the internal CD-ROM (Compact

Disc Read-Only Memory) drive, if your computer has one. (CD-ROM drives

are also sometimes called CD-ROM players.) Refer to Appendix A, “Health,

Safety, and Maintenance Tips,” for information on the proper handling of

CD-ROM discs.

Your internal CD-ROM drive works with CD-ROM discs, standard audio

compact discs (CDs), and single-session or multisession Photo CDs.

Your CD-ROM drive provides access to large amounts of information.

However, you cannot save information on CD-ROM discs. ROM stands

for read-only memory, meaning that the player cannot “write” information

onto CD-ROM discs.

A wide selection of CD-ROM discs is available for entertainment, education,

and business. A typical disc can hold over 650 megabytes (MB) of

information—the equivalent of 270,000 pages of text; up to 8 hours

of speech or music (depending on the sound quality); hundreds of high-

resolution images; or any combination of text, sound, and graphics.

5Using the Internal CD-ROM Drive

Read this chapter for information on

using the internal CD-ROM drive,

if your computer has one.

52 Chapter 5

Inserting a CD-ROM disc

Follow these instructions to insert a CD-ROM disc into your CD-ROM drive.

Then follow the instructions provided with your disc, as well as the

instructions in this manual.

1Start up your Macintosh computer, if it’s not already on.

2Press the Open/Close button to open the tray of the CD-ROM drive.

The tray opens.

3Place a CD-ROM disc in the tray, with the disc label facing up.

Make sure the disc is lying flat and centered in the tray.

Open/Close button

WARNING

It’s best not to use small (8 cm) discs with your computer.

Because your computer is designed to tilt and swivel on its base

(allowing you to position the monitor to minimize glare and reflections),

small discs may not stay in the proper position in the CD-ROM drive. If

you do use a small disc, make sure your computer is as level as possible

before you insert the disc, and don’t tilt and swivel the base while a

small disc is in the drive. If a small disc is not properly seated, the disc

or the CD-ROM drive (or both) may be damaged.

Using the Internal CD-ROM Drive

4Push the tray in, or press the Open/Close button, to close the tray.

In a few moments, an icon for the CD-ROM disc appears on your screen.

CD-ROM disc vibration

Your CD-ROM drive reads CD-ROM discs very quickly, but because of the

high rotation speed of the drive, some CD-ROM discs can wobble and cause

the computer to vibrate. This vibration affects very few CD-ROM discs and

does not damage your computer or the CD-ROM disc itself, but you should

be aware of the vibration in case it occurs.

What causes the vibration? Some CD-ROM disc labels have artwork on them

that can cause the disc’s weight to be slightly off-center. For example, the label

(or “paint”) on the CD-ROM disc may be noticeably thicker on one side than

the other. A slightly off-centered CD-ROM disc can wobble in the drive and

cause your computer to vibrate.

Ejecting a CD-ROM disc

Follow these instructions to open the tray and eject a CD-ROM disc from

your computer.

IMPORTANT

You may not be able to eject a disc if it is being shared. To turn

off file sharing, use the Sharing Setup control panel.

1Open the tray.

There are several ways to open the tray of your CD-ROM drive.

If a CD-ROM disc icon appears on your screen:

mSelect the disc icon on your screen and drag the icon to the Trash.

mClick the disc icon, then choose the Put Away command in the File menu.

mWhile the AppleCD Audio Player window is active, choose Eject CD from

the File menu, or simultaneously press the xand E keys. (AppleCD Audio

Player is a program that allows you to control your CD-ROM drive and is

available in the Apple [ K]menu.)

If no CD-ROM disc icon appears on your screen:

mPress the Open/Close button for your CD-ROM drive.

2Take the CD-ROM disc out of the tray.

Store your disc in a safe place, away from heat, dust, and moisture.

3Push the tray in, or press the Open/Close button, to close the tray.

To avoid possible damage to the tray or the CD-ROM drive, keep the tray

closed when you are not using it.

Playing audio CDs

With your CD-ROM drive and your computer’s built-in speaker, you can play

audio compact discs (CDs) or audio tracks on CD-ROM discs. You can also

attach headphones to the computer to listen to audio CDs and audio tracks.

Note that you may need to set control panel options in order to play audio

CD-ROM discs. Refer to the “Sound” topic area of Macintosh Guide, available

in the Guide (h) menu.

To star t, stop, and otherwise control audio discs, use the AppleCD Audio

Player program, available in the Apple (K) menu. Your audio CD software

will only play tracks that contain audio information. You can listen to an

audio CD or audio tracks in the background while you do other work on your

computer.

54 Chapter 5

Using the Internal CD-ROM Drive

Working with Photo CDs

You can use your CD-ROM drive to open Photo CD images stored on Photo

CDs. A Photo CD image is a digitized version of a standard photograph that

you can open and view on your computer screen.

You can do many things with the images on your Photo CDs:

mOpen and view the images individually on your computer screen.

mView the images on your computer screen in a series, as you would view

a slide presentation.

mCopy and save the images, print them, paste them into word-processing

documents or other documents that accept graphics, and edit them with

a graphics application program.

Photo CD images are an excellent source of graphics for desktop

publishing, multimedia presentations, business documents, and

professional-quality graphic design. For more information on working with

Photo CD images, see the “Disks” or “CD-ROM Discs” topic (depending

on the version of system software you are using) of Macintosh Guide,

available in the Guide (h) menu.

Viewing the contents of a Photo CD

When you double-click a Photo CD file, it is opened by the TeachText or

SimpleText program, unless you select another program to open Photo CD

images. See “Setting Preferences for How Photo CD Images are Displayed”

later in this chapter.

IMPORTANT

If you plan to use TeachText or SimpleText to view Photo CD

images or other large files, you should use the program’s Info window to

assign it more memory. For instructions on assigning memory to a program,

refer to the “Memory” topic area of Macintosh Guide, available in the Guide

(h) menu.

To view images on a Photo CD:

1Insert a Photo CD in the CD-ROM player’s tray, with the disc label facing up.

2Close the tray.

The first time you insert a particular Photo CD, a message appears telling you

the system is creating icons. These icons are tiny representations of the photo

CD’s contents. Click Stop if you want to use generic document icons instead.

After a few moments, an icon for the Photo CD appears on the desktop. The

disc name has the letters “PCD” and an identifying number supplied by the

photofinisher. You cannot change the name of the disc.

By the way: If you choose generic document icons and later decide you want

Photo CD icons instead, you can create them by pressing x-Option as you

insert the Photo CD. Continue holding down the keys until the disc icon

appears.

56 Chapter 5

3Double-click the disc icon to open the Photo CD window.

A Photo CD window always contains a Slide Show, the Slide Show Viewer,

and a Photos folder. The Slide Show is a QuickTime movie that contains all

your images. (See “Viewing Several Images in Sequence,” later in this

chapter, for more information.) The Photos folder holds your individual

images.

The Photo CD window also contains a PHOTO_CD folder that holds

technical information about your Photo CD images. Normally, you won’t need

to use this folder.

4Double-click the Photos folder to open it.

The Photos folder contains five folders. Each folder contains all your Photo

CD images recorded at a particular resolution. (See “A Note About

Resolution” later in this chapter.)

Using the Internal CD-ROM Drive

5Double-click the folder for the resolution you want.

Within the folder, an icon appears for each Photo CD image. Each icon is a

tiny representation of the image the file contains. The image numbers

correspond to the index that comes with your Photo CD.

IMPORTANT

When your system is low on memory, your computer may not be

able to display color icons for your Photo CD images; however, the images

themselves are not affected. To see the color icons, quit all open programs,

restart your computer, and then reopen the Photos folder. See the

documentation or on-screen help that came with your computer for more

information on managing memory.

58 Chapter 5

The icons represent the individual

images on your Photo CD.

6Double-click the icon of the image you want to see.

The image appears in a TeachText or SimpleText window. (You can choose to

have Photo CD images opened by another program. See “Setting Preferences

for How Photo CD Images Are Displayed” later in this chapter).

You can view and print the image, or paste it into your Scrapbook or into a

document created by another program that can handle graphics.

IMPORTANT

You can’t rename or change the Photo CD images on the

CD-ROM disc. To rename or change an image, you first need to copy it to

a hard disk or floppy disk.

Using the Internal CD-ROM Drive

Viewing several images in sequence

A note about resolution

When a Photo CD image is created, it’s recorded at five different levels of

resolution. The higher the resolution, the more information is recorded about

the image, and the sharper the image appears when displayed or printed at

larger sizes. However, high-resolution images take up a lot of memory—up to

18 MB of data for one photograph—which affects file size, as well as the

amount of time it takes to display or print an image.

It’s best to work with a resolution appropriate for your monitor or printer.

Some monitors and printers cannot display or print very high-resolution

images.

For most work, a resolution of 768 x 512 pixels or smaller is suitable. For

detailed work or very high-quality reproductions, you may want to use a

higher resolution.

Make sure to open high-resolution images with application programs designed

to handle large image files. TeachText and SimpleText cannot open very large

files.

Working with Photo CD images in other programs

There are several ways to open and work with Photo CD images in other

programs:

mYou can choose a program that automatically opens a Photo CD image

when you double-click it. See “Setting Preferences for How Photo CD

Images Are Displayed” earlier in this chapter.

mFrom the Slide Show Viewer, you can transfer a displayed image directly to

another program, without copying and pasting. See the next section,

“Transferring the Displayed Image to Another Program.”

mYou can copy and paste an image. See “Copying Images From a Slide

Show” later in this chapter.

Once you’ve opened an image in a program, you can change the image and

save your changes on a hard disk or floppy disk. (The images on the Photo

CD cannot be changed.)

Chapter 6 Troubleshooting

Consult this chapter if you experience

problems using your computer.

When you have questions

If you want to know how to do a particular task with your computer, refer

to Macintosh Guide in the Guide (h) menu. For instructions on using

Macintosh Guide, see Chapter 2 of this manual.

If you have trouble

While you’re using your computer, you may occasionally see a bomb icon

or an error message, or the pointer (8) may “freeze” on the screen.

If you have trouble with your computer, take a few minutes to read the

information in this chapter. If your problem is related to a particular

procedure, you should also look for information on that procedure in

Macintosh Guide, available in the Guide (h) menu. For additional

troubleshooting information and a list of common questions relating to your

system software, see the “Troubleshooting” topic of Macintosh Guide.

6Troubleshooting

If you are unable to access Macintosh Guide (for example, if your screen

is “frozen”), refer to this chapter to see if you can resolve the problem.

Take your time

When you see an error message, you don’t have to take action immediately.

The message stays on the screen until you click the OK button (or Restart) or

turn off the computer.

To help diagnose and correct the problem, gather as much information on the

situation as you can. Then follow the instructions in the next section, “Start

Over.”

mMake a note of exactly what you were doing when the problem occurred.

Write down the message on the screen and its ID number (if any). Also list

the programs you were using and the names of any items you know have

been added to the System Folder since the system software was installed.

This information will help a service person diagnose the problem. (It is

helpful to keep a printed copy of the items in your System Folder. For

instructions on printing the contents of a folder, see the information about

printing in Macintosh Guide, available in the Guide [h] menu.)

mCheck the screen for any clues. Is a menu selected? What programs and

document icons are open? Note anything else that seems relevant.

mIf you were typing text and were not able to save it before the problem

occurred, you can write down the parts of the text still visible on the

screen so that some of your work will be easy to replace.

WARNING

If you have a problem with your computer and nothing

presented in this chapter solves it, consult the service and support

information that came with your computer for instructions on how to

contact an Apple-authorized service provider or Apple for assistance. If

you attempt to repair the computer yourself, any damage you may cause

to the computer will not be covered by the limited warranty on your

computer. Contact an Apple-authorized dealer or service provider for

additional information about this or any other warranty question.

70 Chapter 6

mAsk other Macintosh users about the problem you’re having; they may have

a solution for it.

If you need repair service, consult the service and support information that

came with your computer for instructions on how to contact an Apple-

authorized service provider or Apple for assistance.

If you know that the problem is with a particular application program, contact

the manufacturer of that software for assistance.

Start over

Often you can eliminate a problem simply by clearing the computer’s memory

and starting over.

If you can, save any open documents before restarting the Macintosh. If

your system is frozen and does not respond to anything you do, or if you

have a “bomb” message on the screen, saving may not be possible. You can

try pressing x-Option-Esc to quit the program in use when the problem

occurred; if this works, you can then save the documents open in other

programs before restarting. (Be sure to restart the computer immediately after

you save your documents—quitting a program using x-Option-Esc may leave

corrupted data in the computer’s memory. This corrupted data is erased when

you restart the computer.)

To restart your Macintosh, try the following steps:

1If you can, choose Restart from the Special menu or from the dialog box that’s on the

screen.

Dialog boxes contain messages from the computer. If something goes wrong,

a message may appear on the screen, asking you to restart the computer.

2If you can’t choose Restart, hold down the

and Control keys while you press the

Power key (marked with a triangle).

This key combination restarts the computer. (Use this key combination only

when you can’t choose Restart from the Special menu.)

3If nothing happens, turn off your computer with the power switch, wait at least 10

seconds, and then turn it on again.

Troubleshooting

4If the power switch doesn’t turn off the computer, unplug your Macintosh.

If you suspect that the problem is with other equipment, such as a printer or

an external hard disk that’s attached to your computer, turn that equipment off

for 10 seconds or longer, then turn it on again and restart the Macintosh.

Rebuild your desktop

A process known as “rebuilding the desktop” helps your Macintosh keep

track of data on your startup disks. (Although the hard disk in your computer

is usually the startup disk, you can start up from any other disk that has

system software installed.)

Rebuilding your desktop can solve a number of problems. For example, when

application documents are no longer represented by application-specific icons

(and are instead represented by generic icons on the desktop), rebuilding the

desktop fixes the problem. Afterward, appropriate icons should appear for all

documents.

Some extensions may interfere with rebuilding your desktop. To prevent

problems, you’ll need to turn off all extensions except Macintosh Easy Open

before you rebuild your desktop. When you finish rebuilding the desktop, turn

the extensions you normally use back on.

To rebuild the desktop of a startup disk, follow these steps:

1Save your current set of extensions (those that are on, marked by checkmarks).

a. Open the Extensions Manager control panel by choosing Extensions

Manager from the Control Panels submenu of the Apple () menu.

b. From the Sets pop-up menu, choose Save Set.

c. In the Save Set dialog box, type a name for your set of selected extensions

(for example, “My Extensions”) and click OK. The name of your set is

added to the Sets pop-up menu.

2Choose All Off from the Sets pop-up menu to turn off all extensions.

3Turn on Macintosh Easy Open by clicking it in the list (under Control Panels) so that a

checkmark appears beside it.

4Restart your computer while holding down the Command (

) and Option keys.

Hold down the xand Option keys until you see the dialog box that asks if

you’re sure you want to rebuild your desktop file. When the dialog box

appears, you can release the keys.

72 Chapter 6

5Click OK.

The desktop is rebuilt.

IMPORTANT

Do not stop the desktop-rebuilding process. Doing so could cause

problems with your system software.

6Turn your original set of extensions back on.

a. Open the Extensions Manager control panel by choosing Control Panels

from the Apple () menu. When the Control Panels window appears,

double-click the Extensions manager icon.

b. From the Sets pop-up menu, choose the name you gave your set of

extensions in step 1.

7Restart your computer to activate the extensions.

Solutions to common problems

This section contains descriptions of problems you could experience with

your computer. Some problems may be caused by your CD-ROM drive, so if

you don’t find your problem here, be sure to check the section “Solutions to

CD-ROM Problems” later in this chapter.

The computer is turned on but the screen is dark.

One of the following is probably the cause:

mYou have a screen saver program that darkens the screen when the

computer has not been used for a certain period.

Press a key or move the mouse to turn off the screen saver.

mThe screen control buttons (¸) are not adjusted properly.

Tu r n up the screen’s brightness if necessary.

mThe Macintosh is not getting power.

Check that the computer’s power cord is firmly connected to the computer

and plugged into a grounded electrical outlet, and that the outlet has power.

Troubleshooting

The screen image is off center.

If the picture on your screen appears to be off center, use the centering

controls on the back of the computer to adjust it. Use a small screwdriver to

turn the controls.

The computer’s clock keeps time inaccurately.

Your computer has a clock that runs continuously. When the computer is

turned off, a battery keeps the clock running. If your clock begins to keep

time inaccurately, have your Apple-authorized service provider replace

the battery.

When you start up, a disk icon with a blinking question mark appears in the middle of

the screen.

This icon indicates that your Macintosh cannot find the system software it

needs to start up. One of the following is probably the cause:

mYour computer may be having a problem recognizing external equipment

that uses the Small Computer System Interface (SCSI).

Shut down the computer, turn off all external SCSI equipment, and

disconnect the first SCSI device in the chain from your computer’s SCSI

port. Then restart the computer. If the computer starts up after you

disconnect your SCSI equipment, refer to the manuals that came with the

equipment for information on the proper way to connect SCSI equipment

and assign SCSI ID numbers.

If you have a printer connected to your computer’s SCSI port, make sure

your printer is not supposed to be connected to the printer port instead.

Check the manuals that came with your printer for information on how to

properly connect it.

mSystem software is not installed on the startup hard disk, the system

software is damaged, or the hard disk is not working properly.

Start up your computer using the Disk Tools floppy disk or (if you have a

built-in CD-ROM drive) with the CD-ROM disc that contains system

software. (For instructions on how to start up your computer from the

CD-ROM disc, see “Starting Up From a CD-ROM Disc” in the section

“Initializing a Hard Disk” later in this chapter.) Then follow the

instructions in “Repairing a Damaged Disk” later in this chapter to test

your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or

Reinstalling System Software” later in this chapter to reinstall system

software on your startup hard disk.

When you try to start up from a floppy disk, a disk icon with an X appears in the middle

of the screen and the floppy disk is ejected.

This icon indicates that the floppy disk you tried to start up from is not a

startup disk.

Wait a few seconds. The computer should start up from its internal hard

disk. Make sure you insert floppy disks only after the computer has begun

starting up.

Troubleshooting

A “sad Macintosh” icon appears and the computer won’t start up.

This icon indicates that your Macintosh cannot start up because of a problem

with the system software or the computer hardware.

Eject any floppy disks by turning off the computer and then holding down

the mouse button while you turn the computer on again. Try starting up with

the Disk Tools floppy disk or (if you have a built-in CD-ROM drive) with the

CD-ROM disc that contains system software. (For instructions on how to start

up your computer from the CD-ROM disc, see “Starting Up From a CD-ROM

Disc” in the section “Initializing a Hard Disk” later in this chapter.) If the “sad

Macintosh” icon appears again, consult the service and support information

that came with your computer for information on contacting an Apple-

authorized service provider or Apple for assistance.

The hard disk icon does not appear on the desktop.

If you don’t see a hard disk icon on the desktop, try the following:

mIf the hard disk is your startup disk, start your computer using the Disk

To o ls floppy disk or (if you have a built-in CD-ROM drive) with the

CD-ROM disc that contains system software. (For instructions on how to

start up your computer from the CD-ROM disc, see “Starting Up From a

CD-ROM Disc” in the section “Initializing a Hard Disk” later in this

chapter.) Then follow the instructions in “Repairing a Damaged Disk” later

in this chapter to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in “Installing or

Reinstalling System Software” later in this chapter to reinstall system

software on your startup hard disk.

mUse the Drive Setup program to make the disk available. Drive Setup is

located in the Apple Extras folder. For instructions, start Drive Setup, then

choose Drive Setup Guide from the Guide (h) menu.

mIf the hard disk is internal, shut down your computer, wait at least 10

seconds, and then turn it on again.

76 Chapter 6

mIf the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

mCheck the ID numbers of all SCSI equipment connected to your computer.

See the manuals that came with your SCSI equipment for information on

setting SCSI ID numbers.

Icons do not appear correctly on your screen.

You need to rebuild the desktop—a process that helps your Macintosh keep

track of files and folders on your hard disk. For instructions, see “Rebuild

Your Desktop” in the section “If You Have Trouble” earlier in this chapter.

If icons still do not appear correctly after you rebuild the desktop, restart your

computer while pressing the Shift key to temporarily turn off system

extensions. When you see the “Welcome to Macintosh—extensions off”

message, release the Shift key and press the Option and xkeys until you see a

message asking if you want to rebuild the desktop.

Your Macintosh can’t read a floppy disk.

If you see a message that a floppy disk is unreadable, try one of the following:

mIf the disk has never been used, you may simply need to initialize it. For

instructions, see the “Disks” topic of Macintosh Guide, available in the

Guide (h) menu.

mThe disk may be damaged. See “Repairing a Damaged Disk” later in this

chapter for information on testing and repairing disks.

mThe disk may have been formatted for use on another kind of computer.

You may be able to use a program that lets you work with such disks on

your Macintosh. If you are using a DOS disk, for example, make sure the

PC Exchange control panel exists in the Control Panels folder (in the

System Folder) and that it is enabled. To enable PC Exchange, open the

Extensions Manager control panel and click the PC Exchange item (under

the “Control Panels” heading) to make a check mark appear before it.

mIf the disk is a high-density disk previously used on another computer, the

disk may have been formatted incorrectly as an 800K disk rather than as a

1440K (high-density) disk. If so, use the other computer to copy the disk’s

contents onto a properly formatted disk.

Troubleshooting

You can’t eject a floppy disk.

If you can’t eject a floppy disk in the usual way, try the following in order:

mHold down the xand Shift keys and press the number 1 key on your

keyboard to eject a disk in the internal disk drive.

mTurn off the computer. If the disk isn’t ejected, then hold down the button

on your mouse or other pointing device while you turn the computer

on again.

mLocate the small hole near the disk drive’s opening, and carefully insert the

end of a large straightened paper clip into it. Push gently until the disk is

ejected. Do not use excessive force.

If none of these solutions works, take the computer or disk drive to your

Apple-authorized service provider to have the disk removed.

A dialog box with a bomb appears.

Your system has a software problem.

mWrite down what you were doing when the message appeared, and write

down the message’s text and its number, if there is one.

mRestart your Macintosh. (See “Start Over” in the section “If You Have

Trouble” earlier in this chapter for instructions.) Most software problems

are temporary, and restarting usually corrects the problem.

78 Chapter 6

mCheck the startup disk and application program you were using when the

dialog box appeared. Make sure that all programs, desk accessories, and

system extensions you’re using are compatible with the system software.

Reinstalling the system software may correct the problem.

mIf the bomb only occurs in one application program, try reinstalling the

program from the original disks. If reinstalling doesn’t solve the problem,

contact the manufacturer of the program.

mSometimes incompatible system extensions or control panels can cause

system software problems. Restart while holding down the Shift key to

temporarily turn off all system extensions.

If your computer works normally after you do this, use the Extensions

Manager control panel to turn off individual extensions and control panels.

For detailed instructions, see the “Setting Options” or “Customizing Your

Macintosh” topic (depending on the version of system software you are

using) of Macintosh Guide, available in the Guide (h) menu.

If your computer performs better when a particular extension or control

panel is turned off, contact the extension’s or control panel’s manufacturer

for information or an upgrade.

mIf the problem recurs, you may need to reinstall system software. See

“Installing or Reinstalling System Software” later in this chapter for

instructions.

The pointer (

) doesn’t move when you move the mouse.

One of the following situations is probably the cause:

mYour system has a software problem.

Press x-Option-Esc to quit the application program in use when the

problem occurred. If this works, you can save the documents open in other

programs before restarting.

Restart your Macintosh. See “Start Over” in the section “If You Have

Trouble” earlier in this chapter for instructions.

Troubleshooting

Check the startup disk and program you were using when the problem

occurred. Make sure that all programs, desk accessories, and system

extensions you’re using are compatible with the system software. Try

starting up the computer from the Disk Tools disk or the CD-ROM disc that

contains system software. (For instructions on how to start up your

computer from the CD-ROM disc, see “Starting Up From a CD-ROM

Disc” in the section “Initializing a Hard Disk” later in this chapter.) If your

computer starts up normally, there may be an extension conflict.

If the problem recurs, you may need to reinstall system software. See

“Installing or Reinstalling System Software” later in this chapter for

instructions.

mThe mouse or keyboard is not connected properly.

Turn the computer off using the power switch, check that the mouse and

keyboard cables are connected properly, and then restart the computer.

IMPORTANT

Don’t connect the mouse while the computer is turned on. You

may damage your computer.

mSignals from the mouse are not reaching the computer, either because the

mouse needs cleaning or because there is something wrong with the

mouse.

Clean the mouse according to the instructions in Appendix A, “Health,

Safety, and Maintenance Tips,” of this book.

If you have another mouse or pointing device, try connecting and using it.

(Turn off the computer before connecting it.) If the new device works, there

is probably something wrong with the mouse you replaced.

If none of these procedures solves the problem, consult the service and

support information that came with your computer for instructions on how to

contact an Apple-authorized service provider or Apple for assistance.

Typing on the keyboard produces nothing on the screen.

One of the following is probably the cause:

mYour system has a software problem.

Restart your Macintosh. For instructions, see “Start Over” in the section

“If You Have Trouble” earlier in this chapter.

80 Chapter 6

Check the startup disk and application program you were using when the

problem occurred. Make sure that all programs, desk accessories, and

system extensions you’re using are compatible with the system software.

If the problem recurs, try restarting the computer with system extensions

turned off. (To turn system extensions off, hold down the Shift key while

restarting the computer.) If that doesn’t work, you may need to reinstall

system software. See “Installing or Reinstalling System Software” later in

this chapter for instructions.

mThe computer beeps every time you press a key.

Easy Access is probably turned on. Use the Extensions Manager control

panel to turn off Easy Access. (To open the Extensions Manager control

panel, choose Extensions Manager from the Control Panels submenu of the

Apple [K]Menu.)

mYou haven’t selected any text or set the insertion point (i).

Make sure the program you want to type in is the active program. Then

place the pointer (8)in the active window and click to set an insertion

point (i) or drag to select text (if you want to replace the text with your

typing).

mThe keyboard is not connected properly.

Turn off the computer using the power switch, then check that the keyboard

cable is connected properly at both ends.

If you have a keyboard with an ADB port (marked with the ◊icon) on

each end, turn off the Macintosh using the power switch and plug the

keyboard cable into the other ADB port on the keyboard. (You may have to

unplug the mouse to do this.) Then restart the computer.

mThe keyboard is damaged.

If you have access to another keyboard, try using it instead. (Turn the

computer off before connecting it.) If the new keyboard works, there is

probably something wrong with the one you replaced.

If none of these procedures solves the problem, consult the service and

support information that came with your computer for instructions on how to

contact an Apple-authorized service provider or Apple for assistance.

Troubleshooting

You can’t start an application program or it quits unexpectedly. Or, when you try to open

a program, you see a message that not enough memory is available.

One of the following is probably the cause:

mThe Macintosh ran out of memory.

Quit the programs that you have open and then open the program you want

to use, or restart your Macintosh.

Make sure virtual memory is turned on in the Memory control panel.

For more information on virtual memory, see the “Memory” topic area of

Macintosh Guide, available in the Guide (h) menu.

mThe program needs more memory.

Use the program’s Info window to give it more memory. For more

information on increasing a program’s memory, see the “Memory” topic

area of Macintosh Guide, available in the Guide (h) menu.

mThe program is a non-Power Macintosh application program running in

emulation mode that requires a separate floating-point unit (FPU). It

cannot use the built-in FPU on your computer’s microprocessor.

Check the documentation that came with the program or contact the

program’s manufacturer to find out if the program requires the FPU found

in a non-Power Macintosh chip. If it does, you may need to upgrade to a

Power Macintosh version of the program, or install software that emulates

a non-Power Macintosh FPU. (See your dealer for this software.)

mSometimes incompatible system extensions or control panels can cause

software problems. Restart while holding down the Shift key to temporarily

turn off all system extensions.

If your program works normally after you do this, use the Extensions

Manager control panel to turn off individual extensions and control panels.

For detailed instructions, see the “Setting Options” or “Customizing Your

Macintosh” topic (depending on the version of system software you are

using) of Macintosh Guide, available in the Guide (h) menu.

If your program performs better when a particular extension or control

panel is turned off, contact the software’s manufacturer for information or

an upgrade.

82 Chapter 6

You can’t open a document, or you see a message that an application program can’t

be found.

mSome documents can be opened by more than one application program.

Try starting a program that you think might be able to open the document,

then choose Open from the program’s File menu to try to open the

document.

mPurchase and install the correct software to use the document, or find out

if the creator of the document can convert it to a form that one of your

programs can use.

mDon’t try to open the files in your System Folder. Most of the files in your

System Folder are used by your computer for internal purposes and are not

intended to be opened.

mRebuild your desktop (refer to “Rebuild Your Desktop” in the section “If

You Have Trouble” earlier in this chapter).

mIf the document is from a DOS computer, use the PC Exchange control

panel to specify which Macintosh program will open the document. For

information about working with DOS documents on your Macintosh, see

the information about using DOS files in Macintosh Guide, available in the

Guide (h) menu.

You experience problems using a document from a DOS computer.

If you can’t open a DOS document using a Macintosh program, try the

following:

mOpen the document from within the program by choosing Open in the

program’s File menu.

mUse the PC Exchange control panel to change the document’s type to one

that can be opened by the program.

If a DOS document is displayed incorrectly, or you see strange codes or

characters in the document, try one of the following:

mYour application program may have special procedures for opening and

saving documents with different file formats. See the information that

came with your program.

mTry opening the document in another program.

Troubleshooting

Note: Some characters that can be displayed on the Macintosh are not

accurately displayed on DOS computers, and vice versa.

For more information about working with DOS documents on your

Macintosh, see the information about using DOS files in Macintosh Guide,

available in the Guide (h) menu.

You see a message that your application program can’t be opened because a file can’t

be found.

Power Macintosh programs use special files called shared libraries. Any

necessary shared libraries should be installed automatically when you install

Power Macintosh programs.

Follow the directions that came with your program to reinstall the program. If

the shared library is still missing, contact the software program’s manufacturer

for assistance.

You experience problems using an older Macintosh program.

Some older Macintosh programs are not completely compatible with Power

Macintosh computers. Check with the program’s manufacturer for

compatibility and upgrade information.

Open the Memory control panel and turn off Modern Memory Manager.

For more detailed instructions, see the “Working with Programs” topic area of

mIf you installed the CD-ROM drive after you bought your computer, make

sure the CD-ROM software is installed. (Refer to the documentation that

came with the CD-ROM drive.)

CD-ROM software is already installed on Macintosh computers that come

with CD-ROM drives. You can reinstall it by following the procedure in

“Installing or Reinstalling CD-ROM Software” later in this chapter.

mMake sure that the Apple CD-ROM extension is turned on in the

Extensions Manager control panel.

Your computer displays the message “This is not a Macintosh disk: Do you want to

initialize it?” when you insert a CD-ROM disc in the CD-ROM drive.

mMake sure that the Foreign File Access and Audio CD Access CD-ROM

extensions are installed in your Extensions Folder and are turned on. (If

they are not turned on, use the Extensions Manager control panel to turn

them on and then restart your computer.)

mMake sure the CD-ROM software is installed. (The CD-ROM software is

already installed on Macintosh computers that come with CD-ROM

the manual that came with your drive.

mThe disc may use a format that the Macintosh cannot recognize.

Your computer ejects a CD-ROM disc without giving you any error message.

mMake sure the disc is flat in the tray and the disc label is facing up. If

you’re using a small (8 cm) disc, make sure it’s centered within the tray’s

inner ring.

mThe disc may need to be cleaned. (See “Handling CD-ROM Discs” in the

section “Handling Your Computer Equipment” in Appendix A.) If there are

visible scratches on the shiny side of the disc, you may be able to remove

them with a CD polishing kit (available from your audio CD dealer). If the

scratches can’t be removed, you’ll need to replace the disc.

Troubleshooting

mThe disc may be damaged. Try another disc in the drive, and try the

original disc in another drive. If the original drive reads other discs or if

the original disc doesn’t work in another drive, the disc is probably

damaged. You’ll need to replace the disc.

You can’t open a document on a CD-ROM disc.

mTry opening the application program first; then open the document.

mRead the manual that came with your CD-ROM disc. Some discs come

with software that you need to install on your computer before using the

disc.

mDon’t try to open the files in your System Folder. Most of the files in your

System Folder are used by your computer for internal purposes and are not

intended to be opened.

You can’t save changes you make to information on a CD-ROM disc.

mCD-ROM is a read-only medium. This means that information can be read

(retrieved) from it, but not written (stored) on it. You can save the changed

information on a hard disk or floppy disk.

Problems using ISO 9660 or High Sierra discs

You cannot access files on a CD-ROM disc that uses the ISO 9660 or High Sierra format.

mDiscs in the ISO 9660 and High Sierra disc formats have version numbers

for more information on managing memory).

If your computer’s performance decreases

If you notice a decrease in your computer’s speed and general performance

after you add special software like a control panel, system extension, or

custom utility, it may be because this software does not work well with Power

Macintosh computers.

90 Chapter 6

mTo find out if a system extension or control panel is the problem, use the

Extensions Manager control panel. Open the Extensions Manager control

panel and select “System 7.5 Only” to turn off all system extensions and

control panels that are not part of System 7.5. Restart your computer, then

use the Extensions Manager control panel to turn the system extensions

and control panels back on one at a time, restarting and checking your

computer’s performance each time until you identify the software that is

causing problems. Contact the software’s manufacturer for information or

an upgrade.

mTo find out if a custom utility you’ve added is the problem, drag it out of

the System Folder. (This software may be in the Control Panels folder or

elsewhere inside the System Folder.) Next, restart your computer and check

its performance. If there’s an improvement, the new software was probably

the cause of the problem. Contact the software’s manufacturer for

information or an upgrade.

mIf you turn on both virtual memory and the RAM disk in the Memory

control panel (in the Control Panels folder in the Apple [K] menu), don’t

set both of them at or near their maximum values. Doing so can result in

unpredictable or reduced performance by your computer.

Note: Not all application programs work well with virtual memory turned

on. For more information on both the virtual memory and RAM disk

features, see the Memory topic of Macintosh Guide, available from the

Guide (h) menu.

mRebuild your desktop. For instructions on how to rebuild your desktop, see

“Rebuild Your Desktop” in the section “If You Have Trouble” earlier in this

chapter.

If you still do not notice an improvement, follow the instructions in

“Installing or Reinstalling System Software” later in this chapter to reinstall

system software on your startup hard disk.

Troubleshooting

Solving printer problems

The following suggestions should work for all printers.

mMake sure that the printer driver for your printer is turned on in the

Extensions Manager control panel. (The printer driver should appear in the

Extensions list. To find out the name of the printer driver—for example,

LaserWriter—refer to the documentation that came with your printer.)

mCheck your printer settings in the Chooser, making sure you have selected

the correct printer. Make sure that AppleTalk is on (if you are using a

printer on your network) or that AppleTalk is off (if you are using a serial

printer connected to your computer).

mIf you are using Apple Remote Access, check your network settings. If you

have selected Remote Only, you will not be able to use a printer on your

local network. (When you have a remote-only connection, however, you

can use a serial printer connected directly to your computer.)

mNext, turn off the computer and printer, and check the printer cable

connections.

mIf none of these suggestions solves the problem, reinstall your printer

driver. If your printer is an older model, do not use the driver that came

with the printer. Instead, use the updated printer drivers provided on the

system software CD-ROM disc that came with your Power Macintosh.

These drivers are created especially for use with the Power Macintosh.

Initializing a hard disk

Before you can use a new disk, the disk must be prepared so that the

computer knows where to store information on the disk. This preparation is

called initializing (or formatting) the disk.

When do you need to initialize a hard disk?

The hard disk inside your computer was initialized at the factory, so you

shouldn’t need to initialize it. You need to initialize a hard disk only if one of

the following is true:

mYou purchase a hard disk that has not been initialized at the factory.

mYour hard disk is damaged.

If a hard disk needs to be initialized, the disk’s icon does not appear on the

desktop when you start up the computer using another disk.

Troubleshooting

If the hard disk you want to initialize is not the startup disk, you can use the

Drive Setup program to initialize it. Drive Setup is located on the floppy disk

labeled Disk Tools that came with your computer. If your computer came with

a CD-ROM drive and you didn’t receive floppy disks, you can find Drive

Setup on the CD-ROM disc that contains system software. For instructions,

start Drive Setup and choose Drive Setup Guide from the Guide (h) menu.

If the hard disk you want to initialize is the startup disk, follow the

instructions in this chapter. (First, start up from a CD-ROM disc or a floppy

disk. Then follow the instructions in “How to Initialize a Hard Disk” later in

this section.)

Starting up from a CD-ROM disc

To i n i tia lize, test, or repair a hard disk, or to install system software on a hard

disk, you need to start up your computer from another disk. If your computer

has a CD-ROM drive, you can start up your computer using the CD-ROM

disc containing system software that came with the computer.

To star t up the computer using the CD-ROM disc, follow these steps:

1Turn your computer on.

2When you see the desktop on your screen, press the Open/Close button on your

CD-ROM drive, and insert the CD-ROM disc containing system software into the drive.

3Hold down the “c” key on your keyboard and restart your computer.

Continue to hold down the key until you see the “Welcome to Macintosh”

message.

WARNING

Initializing a disk erases any information that may be on it.

Before you initialize a damaged disk, try to repair it as described in

“Repairing a Damaged Disk” later in this chapter.

96 Chapter 6

Starting up from a floppy disk

To i n i tia lize, test, or repair a hard disk, or to install system software on a

hard disk, you need to start up your computer from another disk. If you don’t

have a built-in CD-ROM drive, you can start up the computer using either the

Disk Tools or Install Me First floppy disk that came with your computer.

To start up your computer using a floppy disk, follow these steps:

1Shut down your computer.

2Insert the floppy disk into the disk drive.

If you want to initialize, test, or repair your hard disk, use the Disk Tools disk

to start up your computer. If you want to install system software, use the

Install Me First disk.

3Turn on your computer.

How to initialize a hard disk

You initialize a hard disk by using a program called Drive Setup, which is on

the CD-ROM disc that contains system software. If your computer did not

come with a CD-ROM drive, Drive Setup is on the Disk Tools floppy disk that

came with your computer. (To initialize a hard disk from another

manufacturer, use the utility software that came with the hard disk.)

1Start up your computer from the CD-ROM disc that contains system software or from the

Disk Tools

disk.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy

Disk” earlier in this section.

2Open the Drive Setup program.

You may need to look in a folder called Utilities to find Drive Setup.

Troubleshooting

3In the list of drives, click the disk you want to initialize.

4Click Initialize to initialize the hard disk.

5Click Quit when you see a message reporting that initialization was successful.

If a message reports that initialization failed, try again. If initialization

fails a second time, take your computer to your Apple-authorized service

provider for repair. Consult the service and support information that came

with your computer for information about the service options available for

your computer.

Repairing a damaged disk

Disks can become damaged by repeated use and handling.

When do you need to repair a disk?

If you see a message reporting that a disk is damaged or unreadable, you may

need to repair the disk.

Tr y th ese suggestions first

If you can’t start up from a hard disk or you don’t see the hard disk icon on the

desktop, try the following:

98 Chapter 6

Click the drive you

want to initialize...

...then click Initialize.

mIf the hard disk is internal, shut down your Macintosh, wait at least 10

seconds, and then turn it on again. If you still don’t see the hard disk, shut

down your Macintosh again and disconnect all external SCSI devices. If

this solves the problem, check the ID numbers and termination of the SCSI

devices as described in the next item before reattaching the devices to your

computer.

mCheck the ID numbers of all SCSI equipment connected to your computer.

Each device must have a unique ID number (the computer itself has the ID

number 7). Also check that the chain of devices is terminated properly. For

information on setting SCSI ID numbers and terminating a SCSI chain,

see the manuals that came with your SCSI equipment.

mIf the hard disk is external, make sure that it is turned on and that its cable

is connected firmly; then restart the Macintosh.

mIf the hard disk is your startup disk, start up with a different startup disk.

If the hard disk’s icon appears on your desktop, reinstall system software

on the hard disk (see “Installing or Reinstalling System Software” later

in this chapter).

mTest th e disk by following the instructions that come next.

How to test a hard disk

You can test a hard disk with the Drive Setup program, which is on the

CD-ROM disc that contains system software. If your computer did not come

with a CD-ROM drive, Drive Setup is on the Disk Tools floppy disk that came

with your computer.

1Start up your computer from the CD-ROM disc that contains system software or from the

Disk Tools

disk.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy

Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Open the Drive Setup program.

You may need to look in a folder called Utilities to find Drive Setup.

Troubleshooting

3In the list of drives, click the disk you want to test.

4Open the Functions menu and choose Test Disk.

5When a message tells you that testing is complete, click Quit.

If the test reveals a problem, you may be able to correct it by using Disk First

Aid or another disk repair program (see the instructions in the next section),

or you may need to reinitialize the disk (see “Initializing a Hard Disk” earlier

in this chapter). Consult an Apple-authorized service provider for assistance if

necessary. (See the service and support information that came with your

computer for information about the service options available for your

computer.) If you had a hard disk from another manufacturer installed after

you bought your computer, use the software that came with the disk or contact

the disk vendor to get the latest version of software.

100 Chapter 6

How to repair a hard disk or floppy disk

You can repair some types of disk damage by using the Disk First Aid

program, which is included either on the CD-ROM disc containing system

software that came with your computer or on the Disk Tools floppy disk.

1Start up your computer from the CD-ROM disc that contains system software or from the

Disk Tools

disk.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy

Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Open the Disk First Aid icon.

You may need to look in a folder called Utilities to find Disk First Aid.

3Click the icon of the disk you want to test.

Disk icons appear in a box at the top of the Disk First Aid window.

101

Troubleshooting

4Click Repair to begin testing and repairing the disk.

You can’t repair the startup disk or the disk that contains the Disk First Aid

program, but you can test these disks by clicking Verify. If the program

reveals a problem with either of these disks, start up the computer from

another disk so that you can repair the damaged disk.

If you want to test and repair another disk, click its icon and then click

Repair.

5When testing and repair are finished, choose Quit from the File menu.

If Disk First Aid cannot correct the problem

mTry repairing the disk again. Sometimes repeating the process corrects the

problem.

mUse another disk repair or recovery program. Some disk repair programs

let you recover information from a damaged disk.

mConsult a computer repair specialist for help.

mOnce you have recovered all the information you can, erase (reinitialize)

the disk. If initialization doesn’t work, discard the damaged disk (if it’s a

floppy disk), or take it to your Apple-authorized service provider for repair

(if it’s a hard disk).

Installing or reinstalling system software

System software is the set of programs and other files that your computer uses

to start itself up, keep track of your files, and run the application programs

you use. System software is kept in the folder called the System Folder. When

you turn on your computer, it looks for a startup disk, which is a disk that

contains the system software. The startup disk is usually the hard disk that’s

inside your computer, though another hard disk or a floppy disk can also be a

startup disk.

The accessory kit that came with your Macintosh provides system software on

either a set of floppy disks or a CD-ROM disc. You can use the floppy disks

or the CD-ROM disc to install the system software on your Macintosh if you

need to do so.

102 Chapter 6

When should you install system software?

Your Macintosh came with all the necessary system software installed on its

internal hard disk, so you don’t need to install system software on that disk

unless you encounter software problems.

If you have a new hard disk or a newly initialized hard disk that doesn’t

contain system software, or if you want to upgrade to a more recent version of

system software on a hard disk, follow the instructions in “Installing System

Software” later in this chapter.

When should you reinstall system software?

If you have a problem with your system software, you may see this icon in the

middle of the screen:

If this icon appears, follow the instructions in “Repairing a Damaged Disk”

earlier in this chapter to test your startup hard disk and repair any damage.

If repairing the disk doesn’t help, follow the instructions in the next section,

“Installing System Software,” to reinstall system software on your startup

hard disk.

Installing system software

Follow the steps in this section to do what is commonly called a “normal”

installation of system software.

If you’re installing system software on a hard disk for the first time, make sure

that your hard disk has been initialized, a process that prepares the disk to

store information. If you see the hard disk’s icon on the desktop when you

start up the computer, the disk has been initialized. If no disk icon appears

when you start up, see “Initializing a Hard Disk” earlier in this chapter for

instructions.

103

Troubleshooting

To do a normal installation, follow these steps:

1Start up your computer from the

Disk Tools

disk or the CD-ROM disc that contains

system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy

Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Find and open the Disk First Aid icon.

You may need to look in a folder called Utilities to find Disk First Aid.

After Disk First Aid starts, follow the instructions on the screen. Disk First

Aid checks your hard disk for any problems.

3When Disk First Aid has finished checking your hard disk, choose Quit from the

File menu.

4Open the Drive Setup program.

You use the Drive Setup program to update your hard disk.

5In the list of drives, click your startup disk.

6Choose Update Driver from the Functions menu.

7When the update process is finished, quit Drive Setup.

106 Chapter 6

Doing a clean installation of system software

The steps in this section outline what is commonly called a “clean”

installation of system software. A clean installation allows you to discover

which item in your System Folder is causing a problem. A clean installation

creates a brand new System Folder and saves everything in your original

System Folder in a different location. You can then follow the instructions in

“Replacing Special Software,” later in this chapter, to reinstall system

extensions, control panels, and other special software one at a time from the

old System Folder to the new System Folder. This procedure allows you to

determine which item in the old System Folder was the source of the

problem.

Do a clean installation if you can’t determine what is damaged in your System

Folder (especially if you think any special software, such as control panels,

system extensions, or custom utilities, may be causing the problems you’re

experiencing). You should also do a clean installation if you’re still having

problems with your computer after you’ve reinstalled system software by

doing a normal installation.

To do a clean installation, follow these steps:

1Start up your computer from the

Disk Tools

disk or the CD-ROM disc that contains

system software.

See “Starting Up From a CD-ROM Disc” or “Starting Up From a Floppy

Disk” in the section “Initializing a Hard Disk” earlier in this chapter.

2Find and open the Disk First Aid icon.

You may need to look in a folder called Utilities to find Disk First Aid.

Replacing special software

Special software consists of items such as control panels, system extensions,

custom utilities, fonts, or Apple menu items that you may have had in your

old System Folder. To make sure that special software does not create any

conflicts with other programs on your computer, follow this procedure to

safely replace these items in your new System Folder:

1Copy any special software items from the Previous System Folder back to your System

Folder one item at a time, restarting the computer after copying each item.

IMPORTANT

Be very careful not to replace (copy over) any of the files in the

System Folder with files from the Previous System Folder.

2Check after each restart to make sure your computer is not having any software

problems.

If any of your special software items cause software problems, contact the

software manufacturer for assistance or an upgrade.

Doing a custom installation

For most Macintosh users, the Easy Install procedure described in the

previous sections is appropriate, because it automatically installs all the items

you need. However, if you’d like to select a combination of system software

files for your specific needs, you can customize your system software

installation. You use custom installation to install or update one or more

specific files, or to save space on your hard disk by installing only the files

you want.

112 Chapter 6

Installing or reinstalling CD-ROM software

CD-ROM software is a set of programs and files that allow your CD-ROM

drive to work correctly with your computer and allow it to play different

kinds of CDs, like Photo CDs or audio CDs. If your computer came with a

CD-ROM drive installed, the CD-ROM software is part of system software

and was preinstalled for you on your computer’s hard disk. (It is also available

on floppy disks and a CD-ROM disc that came with your Macintosh.)

If you added a CD-ROM drive after you bought your computer, the CD-ROM

software is probably on floppy disks that came with the drive.

When should you install or reinstall CD-ROM software?

If your Macintosh came with the CD-ROM drive already installed, you don’t

need to install the CD-ROM software unless you encounter problems. (See

“Solutions to CD-ROM Problems” earlier in this chapter for descriptions of

the kinds of problems you might encounter.)

If you added a CD-ROM drive after you bought your computer, you should

install the CD-ROM software before you attempt to use the CD-ROM drive.

For your own safety and that of your equipment, follow all the instructions in

Health-related information about computer use

Muscle soreness, eye fatigue, and other discomforts and injuries sometimes

associated with using computers can occur from performing any number of

activities. In fact, misuse of the same muscles during multiple activities can

create a problem that might not otherwise exist. For example, if you engage in

nonwork activities that involve repetitive stress on the wrist—such as

bicycling—and also use your computer’s keyboard improperly, you may

increase your likelihood of developing wrist problems. Some individuals are

at greater risk of developing these problems because of their health,

physiology, lifestyle, and general exposure to stress. Work organization and

conditions, such as workstation setup and lighting, also play a part in your

overall health and comfort. Preventing health problems is a multifaceted task

that requires careful attention to the way you use your body every hour of

every day.

The most common health effects associated with using a computer are

musculoskeletal discomfort and eye fatigue. We’ll discuss each area of

concern below.

117

Appendix A

Health, Safety, and Maintenance Tips

Read this appendix for important

health and safety instructions,

as well as tips on keeping your

computer in good working order.

Musculoskeletal discomfort

As with any activity that involves sitting for long periods of time, using a

computer can make your muscles sore and stiff. To minimize these effects, set

up your work environment carefully, using the guidelines that follow, and take

frequent breaks to rest tired muscles. To make working with your computer

more comfortable, allow enough space in your work area so that you can

change position frequently and maintain a relaxed posture.

Another type of musculoskeletal concern is repetitive stress injuries (RSIs),

also known as cumulative trauma disorders (CTDs). These problems can

occur when a certain muscle or tendon is repeatedly overused and forced into

an unnatural position. The exact causes of RSIs are not totally understood, but

in addition to awkward posture, such factors as the amount of repetition, the

force used in the activity, the individual’s physiology, workplace stress level,

and lifestyle may affect the likelihood of experiencing an RSI.

RSIs did not suddenly arise when computers were invented; tennis elbow and

writer’s cramp, for example, are two RSIs that have been with us for a long

time. Although less common than other RSIs, one serious RSI discussed more

often today is a wrist problem called carpal tunnel syndrome, which may be

aggravated by improper use of computer keyboards. This nerve disorder

results from excessive pressure on the median nerve as it passes through the

wrist to the hand.

This section offers advice on setting up your work area to enhance your

comfort while you use your computer. Since the effects of repetitive

movements associated with using a computer can be compounded by those of

other work and leisure activities to produce or aggravate physical problems,

proper use of your computer system must be considered as just one element

of a healthy lifestyle.

No one, of course, can guarantee that you won’t have problems even when you

follow the most expert advice on using computer equipment. You should

always check with a qualified health specialist if muscle, joint, or eye

problems occur.

Eye fatigue

Eye fatigue can occur whenever the eyes are focused on a nearby object for a

long time. This problem occurs because the eye muscles must work harder to

view an object that’s closer than about 20 feet (6 meters). Improper lighting

can hasten the development of eye fatigue. Although eye fatigue is annoying,

there’s no evidence that it leads to permanent damage.

Whenever you’re engaged in an activity that involves close-up work—such as

reading a magazine, doing craft work, or using a computer—be sure to have

sufficient glare-free lighting and give your eyes frequent rest breaks by

looking up and focusing on distant objects. Remember to have your eyes

examined regularly.

To prevent discomfort and eye fatigue:

mArrange your work space so that the furniture is properly adjusted for you

and doesn’t contribute to an awkward working posture.

mTa ke frequent short breaks to give your muscles and eyes a chance to rest.

Arranging your office

Here are some guidelines for adjusting the furniture in your office to

accommodate your physical size and shape.

mAn adjustable chair that provides firm, comfortable support is best. Adjust

the height of the chair so your thighs are horizontal and your feet flat on

the floor.

The back of the chair should support your lower back (lumbar region).

Follow the manufacturer’s instructions for adjusting the backrest to fit your

body properly.

mWhen you use the computer keyboard, your shoulders should be relaxed.

Your upper arm and forearm should form an approximate right angle, with

your wrist and hand in roughly a straight line.

119

Health, Safety, and Maintenance Tips

You may have to raise your chair so your forearms and hands are at the

proper angle to the keyboard. If this makes it impossible to rest your feet

flat on the floor, you can use a footrest with adjustable height and tilt to

make up for any gap between the floor and your feet. Or you may lower

the desktop to eliminate the need for a footrest. Another option is to use a

desk with a keyboard tray that’s lower than the regular work surface.

mPosition the mouse at the same height as your keyboard. Allow adequate

space to use the mouse comfortably.

mArrange the monitor so the top of the screen is slightly below your eye

level when you’re sitting at the keyboard. The best distance from your eyes

to the screen is up to you, although most people seem to prefer 18 to 28

inches (45 to 70 cm).

mPosition the computer to minimize glare and reflections on the screen from

overhead lights and windows.

Thighs horizontal

120 Appendix A

Avoiding fatigue

mChange your seated position, stand up, or stretch whenever you start to feel

tired. Frequent short breaks are helpful in reducing fatigue.

mUse a light touch when typing or using a mouse and keep your hands and

fingers relaxed.

mSome computer users may develop discomfort in their hands, wrists, or

arms after intensive work without breaks. If you begin to develop chronic

pain or discomfort in your hands, wrists, or arms, consult a qualified

health specialist.

mAllow adequate workspace so that you can use your keyboard and mouse

comfortably. Place papers or other items so you can view them easily while

using your computer. A document stand may make reading papers more

comfortable.

mEye muscles must work harder to focus on nearby objects. Occasionally

focus your eyes on a distant object, and blink often while you work.

mClean your screen regularly. Keeping the screen clean helps reduce

unwanted reflections.

What about electromagnetic emissions?

There has been recent public discussion of the possible health effects of

prolonged exposure to extremely low frequency (ELF) and very low

frequency (VLF) electromagnetic fields. Such fields are associated with

electromagnetic sources such as television sets, electrical wiring, and some

household appliances—as well as computer monitors.

Apple has reviewed scientific reports and sought the counsel of government

regulatory agencies and respected health organizations. Based on the

prevailing evidence and opinions, Apple believes that the electric and

magnetic fields produced by computer monitors do not pose a health risk.

In response to those customers who wish to reduce their exposure to

electromagnetic fields, Apple has lowered the emission levels of our products.

We are also actively encouraging further scientific research so we can

continue to promote the health and safety of our customers and employees.

121

provides instructions for adding memory (including an optional memory

cache) to your computer.

Installing an expansion card or additional memory involves three steps:

mopening the computer

minserting the card or memory module into a specific slot or socket

mclosing the computer

About expansion cards and other options for your Macintosh

Expansion cards are printed circuit boards that can be installed in your

computer to give it special features, such as enhanced video capabilities,

networking and communications, and additional processing power. Your

Macintosh has slots available for three different kinds of expansion cards:

man LC-processor-direct slot (LC-PDS) for most expansion cards

ma communication slot for an internal modem or Ethernet card

ma video-in slot for a card that brings signals into the computer from a

videocassette recorder (VCR), laserdisc player, video camera, or

similar device

133

Appendix B

Installing Expansion Cards and Adding Memory

Read this appendix for

instructions on installing an

expansion card in your computer.

You can also install the following additional options in your Macintosh:

man Apple External Video Connector kit that allows video mirroring on an

external monitor

ma TV tuner card that allows you to watch TV on your Macintosh

To i n s t a ll a video input card, an Apple External Video Connector kit, or a TV

tuner card, follow the instructions that came with the kit or card.

WARNING

To avoid damaging your computer and expansion card, do not

attempt to install any expansion card without first checking the

documentation for that card. If the documentation specifies that an

Apple-certified technician must install the card (usually because

the installation requires special training or tools), consult the service

and support information that came with your computer for instructions

on how to contact an Apple-authorized service provider or Apple for

assistance. If you attempt to install the card yourself, any damage you

may cause to your computer or card will not be covered by the limited

warranty on your computer. If the card is not an Apple-labeled product,

check with an Apple-authorized dealer or service provider to see if you

can install it yourself.

About memory

You can have memory—dynamic random-access memory (DRAM)—added

to your computer in packages called Single Inline Memory Modules, or

SIMMs. You can also upgrade your computer’s memory by installing a

High Performance Module (256K Level 2 Cache).

DRAM configurations

Your computer can use any DRAM configuration with SIMMs of these sizes:

1, 2, 4, 8, 16, or 32 megabytes (MB). The exact configuration depends on the

density of the DRAM chips that are mounted on the SIMMs. (The SIMMs

support both 2K and 4K refresh rates.)

IMPORTANT

The SIMMs should be 32-bit-wide, 72-pin fast-paged mode, with

70-nanosecond (ns) RAM access time or faster. SIMMs from older Macintosh

computers are not compatible with your computer and should not be used.

If you decide to have additional DRAM installed in your computer, the

SIMMs can be installed one-at-a-time in any order in either of the memory

slots.

Cache configurations

A memory cache provides an overall increase in your computer’s

performance. You can add a cache by installing a High Performance Module

(256K Level 2 Cache) on the main logic board of your computer.

WARNING

Although instructions for installing SIMMs are provided in

this manual, Apple Computer strongly recommends that you have an

Apple-certified technician install additional DRAM or cache. Consult

the service and support information that came with your computer for

instructions on how to contact an Apple-authorized service provider or

Apple for service. If you install additional SIMMs yourself, you risk

damaging your equipment, and this damage is not covered by the

limited warranty on your computer. See an Apple-authorized dealer or

service provider for additional information about this or any other

warranty question.
