Whats Next?
You’ve done everything you need to get your iMac G5 up and running. The first time
you turn on your computer, the Setup Assistant starts. The Setup Assistant helps you
enter your Internet and email information and set up a user on your computer. If you
already have a Mac, the Setup Assistant can help you automatically transfer files,
applications, and other information from your previous Mac to your new iMac G5.
Transferring Information to Your iMac G5
You can use the Setup Assistant to automatically transfer information from another
Mac to your new iMac G5. To transfer information, make sure of the following:
Â
Your other Mac must have built-in FireWire and support FireWire Target Disk Mode.
Â
Your other Mac must have Mac OS X v10.1 or later installed.
Â
You must have a FireWire cable to connect the two computers.
The Setup Assistant takes you through the process of transferring your information—
just follow the onscreen instructions. Transferring information to your iMac G5 does not
affect the information on your other Mac. Using the Setup Assistant, you can transfer:
Â
User accounts, including preferences and email
Â
Network settings, so your new computer is automatically set up to work with the
same network settings as your other Mac
Â
Applications folder so that the applications you used on your other Mac are now on
your new iMac G5 (you may have to reinstall some of the applications you transfer)
Â
Files and folders stored on your hard disk.
If you don’t use the Setup Assistant to transfer information when you first start up your
iMac G5, you can do it later using the Migration Assistant. Open the Applications folder,
open Utilities, and double-click the Migration Assistant icon.
Note:
If you transfer information later using the Migration Assistant, make sure File
Vault is turned off on the older computer. To turn off File Vault, choose Apple (
) >
System Preferences, click Security, and follow the onscreen instructions.
Setting Up Your iMac G5 for the Internet
If you didn’t transfer your network settings, the Setup Assistant can also take you
through the process of setting up your computer to connect to the Internet. For home
users, Internet access requires an account with an Internet service provider (ISP). Fees
may apply. If you have an Internet account, see Appendix C, “Connecting to the
Internet,” on page 65 for information you’ll need to enter.

AirPort Extreme Wireless Networking
Your iMac G5 comes with AirPort Extreme technology installed. AirPort offers an easy
and affordable way to provide wireless Internet access anywhere in the home, at work,
or in the classroom. Instead of using traditional cables, AirPort uses wireless local area
network (LAN) technology to provide wireless communication between multiple
computers. Through a wireless network, you can set up access to the Internet, transfer
files, play multiplayer games, and more.
Note: You also need an AirPort Base Station and Internet access (fees may apply). Some
Internet service providers are not currently compatible with AirPort. Range may vary
with site conditions.
How AirPort Provides Wireless Internet Access
With AirPort, you set up a wireless connection to a device known as a base station,
which has a physical connection to the Internet. AirPort technology works like a
cordless telephone. With AirPort Extreme technology, your computer makes a wireless
connection to the base station, which is connected to the Internet via a telephone line
or a DSL or cable modem.

Bluetooth Wireless Technology
Your iMac G5 comes with Bluetooth wireless technology installed. Bluetooth lets you
make short-range wireless connections between desktop and portable computers,
personal digital assistants (PDAs), mobile phones, camera phones, printers, digital
cameras, and wireless input devices, such as the Apple Wireless Keyboard and Apple
Wireless Mouse (available for purchase at www.apple.com/store).
Bluetooth wireless technology eliminates the need for many cables that traditionally
connect devices together. Bluetooth enabled devices can connect to each other
wirelessly at distances up to 10 meters (33 feet).
With Bluetooth wireless technology, you can do the following:
 Use your iMac G5 to communicate with a Bluetooth enabled mobile phone. Your
phone can act as a modem to connect you to a wireless service provider, at speeds
of up to 56 kilobits per second (kbit/s), so you can use your mobile phone to access
the Internet.
 Exchange files between Bluetooth enabled computers and devices, even Mac to PC.
Apple still recommends the use of AirPort Extreme wireless networking, however, for
anything but the smallest files.
 Synchronize data between your computer and a Bluetooth enabled PDA. Using
iSync, you can perform a hot sync operation without cables or send your business
card or calendar events directly to a colleagues PDA.
 Use a Bluetooth wireless keyboard or mouse.
 Print to a Bluetooth printer.
 Use a Bluetooth headset.

5 Troubleshooting
Occasionally you may have problems while working with
your iMac G5. This chapter gives you some solutions to
try when you have a problem.
This chapter contains solutions to problems that prevent you from working with your
computer, such as a system freeze or a computer that will not start up. You can find
more troubleshooting information in Mac Help (see page 22) and on the Apple Service
and Support website at www.apple.com/support.
When you experience a problem with your computer, there is usually a simple and
quick solution. When you encounter a problem, try to make a note of things you did
before the problem occurred. This will help you narrow down the possible causes of
the problem and then find the answers you need. Things to note include:
 The applications you were using when the problem occurred. Problems that occur
only with a specific application may indicate that the application is not compatible
with the version of the Mac OS installed on your computer.
 Any software that you recently installed. Certain applications install extensions that
may not be compatible with the Classic environment.
 Any new hardware (such as additional memory or a peripheral) that you connected
or installed.
Problems That Prevent You From Using Your Computer
If the computer won’t respond or the pointer won’t move
 First, make sure the mouse and keyboard are connected. Unplug and then plug in
the connectors and make sure they are secure. If you have a wireless keyboard or
mouse, make sure the batteries are fresh.
 If that doesn’t work, try to force problem applications to quit. Hold down the Option
and Command (x) keys and then press the Esc key. If a dialog appears, select the
application and click Force Quit. Then save your work in any open applications and
restart the computer to be sure the problem is entirely cleared up.
54 Chapter 5 Troubleshooting
 If you are unable to force the application to quit, press and hold the power button
(®) on the back of the computer for a few seconds to shut down the computer.
 If that doesn’t work, unplug the power cord from the computer. Then plug the power
cord back in and press the power button (®) on the computer to turn it on.
If the problem occurs frequently when you use a particular application, check with the
applications manufacturer to see if it is compatible with your computer.
For support and contact information about the software that came with your
computer, go to www.apple.com/guide.
If the problem occurs frequently, you may need to reinstall your system software
(see “Reinstalling the Software That Came With Your Computer” on page 55).
If the computer freezes during startup or you see a flashing question mark
 Wait a few seconds. If the computer doesn’t start up after a delay, shut down your
computer by pressing and holding the power button (®) for about 5 seconds, until
the computer shuts down. Then hold down the Option key and press the power
button (®) again to start up your computer. When your computer starts up, click the
hard disk icon, then click the right arrow.
 After the computer starts up, open System Preferences and click Startup Disk. Select
a local Mac OS X System folder.
 If the problem occurs frequently, you may need to reinstall your system software
(see “Reinstalling the Software That Came With Your Computer” on page 55).
If the computer won’t turn on or start up
 Make sure the power cord is plugged into the computer and into a functioning
power outlet.
 If that does not work, press the power button (®) and immediately hold down the
Command (x), Option, P, and R keys until you hear the startup sound a second time.
 If you recently installed additional memory, make sure that it is correctly installed
and that it is compatible with your computer. See whether removing it allows the
computer to start up (see page 41).
 If that does not work, unplug the power cord and wait at least 30 seconds. Plug the
power cord back in and press the power button (®) again to start up your computer.
 If you are still unable to start up your computer, see the service and support
information that came with your iMac G5 for information on contacting Apple for
service.

Connectors and Ports
Never force a connector into a port. If the connector and port don’t join with
reasonable ease, they probably don’t match. Make sure that the connector matches the
port and that you have positioned the connector correctly in relation to the port.
Avoid Hearing Damage
Ergonomics
Chair
An 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.
Warning: Permanent hearing loss may occur if earbuds or headphones are used at
high volume. You can adapt over time to a higher volume of sound, which may sound
normal but can be damaging to your hearing. Set your iMac G5 volume to a safe level
before that happens. If you experience ringing in your ears, reduce the volume or
discontinue use of earbuds or headphones with your iMac G5.
Thighs tilted slightly
Shoulders relaxed

Lower back supported
Feet flat on the floor
or on a footrest
Top of the screen at or slightly below
eye level (You may need to adjust the
height of your display by raising or
lowering your work surface.)
Clearance under work surface
45–70 cm (18–28 in.)
64 Appendix B Care, Use, and Safety Information
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.
Display
Arrange the display 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).
Position the display to minimize glare and reflections on the screen from overhead
lights and windows.
Mouse
Position the mouse at the same height as your keyboard and within a comfortable
reach.
Keyboard
When you use the keyboard, your shoulders should be relaxed. Your upper arm and
forearm should form an angle that is slightly greater than a right angle, with your wrist
and hand in roughly a straight line.
Use a light touch when typing and keep your hands and fingers relaxed. Avoid rolling
your thumbs under your palms.
Change hand positions often to avoid fatigue. Some 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.

Network Connections
If you have two or more computers attempting to share an Internet connection, be
sure that your network is set up properly. You need to know if your ISP provides only
one IP address or if it provides multiple IP addresses, one for each computer.
If only one IP address is used, then you must have a router capable of sharing the
connection, also known as network address translation (NAT) or “IP masquerading.” For
setup information, check the documentation provided with your router or ask the
person who set up your network. The AirPort Extreme Base Station may be used to
share one IP address among multiple computers. For information on using the AirPort
Extreme Base Station, check the onscreen help or visit the Apple AirPort website at
www.apple.com/airport.
If you cannot resolve the issue using these steps, contact your ISP.

Information
Notify Your Telephone Company
Some telephone companies require that you notify
the local business office when you hook up a
modem to their lines.
Information You Need in the United States
The internal modem complies with Part 68 of the
FCC rules. On the back of this equipment is a label
that contains, among other information, the FCC
registration number and ringer equivalence number
(REN). If requested, provide this information to your
telephone company.
 Ringer equivalence number (REN): 0.1B The REN is
useful to determine the quantity of devices you
may connect to your telephone lines and still have
all those devices ring when your telephone
number is called. In most, but not all areas, the
sum of the RENs of all devices connected to one
line should not exceed five (5.0). To be certain of
the number of devices you may connect to your
line, as determined by the REN, you should contact
your local telephone company to determine the
maximum REN for your calling area.
 Telephone jack type: USOC, RJ-11 An FCC-compliant
telephone cord and modular plug are provided
with this equipment. This equipment is designed
to be connected to the telephone network or
premises wiring using a compatible modular jack
that complies with Part 68 rules. See the
installation instructions for details.
Telephone Line Problems
If your telephone doesn’t work, there may be a
problem with your telephone line. Disconnect the
modem to see if the problem goes away. If it doesn’t,
report the problem either to your local telephone
company or to your companys telecommunications
people.
If disconnecting the modem eliminates the problem,
the modem itself may need service. See the service
and support information that came with your Apple
product for instructions on how to contact Apple or
an Apple-authorized service provider for assistance.
If you do not disconnect your modem when it is
adversely affecting the telephone line, the telephone
company has the right to disconnect your service
temporarily until you correct the problem. The
telephone company will notify you as soon as
possible. Also, you will be informed of your right to
file a complaint with the FCC.
The telephone company may make changes in its
facilities, equipment, operations, or procedures that
could affect the operation of your equipment. If this
happens, the telephone company will provide
advance notice in order for you to make the
necessary modifications to maintain uninterrupted
service.
The internal modem will not work with party lines,
cannot be connected to a coin-operated telephone,
and may not work with a private branch exchange
(PBX).
Telephone Consumer Protection Act
The Telephone Consumer Protection Act of 1991
makes it unlawful for any person to use a computer

telephone fax machine unless such message clearly
contains, in a margin at the top or bottom of each
transmitted page or on the first page of the
transmission, the date and time it was sent and an
identification of the business or other entity, or
individual sending the message and the telephone
number of the sending machine of such business,
entity, or individual.
