Q Migration Assistant

Your iMac is designed so that you can easily set it up and start using it right away. If you've never used an iMac or are new to Mac computers, read this chapter for instructions about getting started.

Important: Read all the setup instructions in this chapter and the safety information starting on page 62 before you plug your iMac into a power outlet.

If you are an experienced user, you may already know enough to get started.
Make sure you look over the information in Chapter 2, "Life with Your iMac," to find out about the new features of your iMac.

Answers to many questions can be found on your iMac in Mac Help. For information about Mac Help, see "Getting Answers" on page 32.

Remove any protective film from the outside of your iMac before you set it up.

What's in the Box

Your iMac comes with an Apple Wireless Keyboard, a wireless Apple Magic Mouse, and an AC power cord. If you ordered an Apple Remote, it's also in the box.

Apple Magic Mouse

Apple Wireless Keyboard

AC power cord

Setting Up Your iMac

Follow these steps to set up your iMac. Wait until Step 4 to turn on your iMac.

Step 1: Pass the power cord through the hole in the stand, plug it into the power port on the back of your iMac, and then plug the cord into a power outlet.

Step 2: To access the Internet or a network, connect one end of an Ethernet cable to the Ethernet port on your iMac. Connect the other end to a cable modem, a DSL modem, or a network.

Your iMac comes with AirPort (802.11n) technology for wireless networking.

For information about setting up a wireless connection, choose Help > Mac Help and search for "AirPort."

To use a dial-up connection, you need an external USB modem. Plug the modem into a USB port on your iMac, and then use a phone cord to connect the modem to a phone jack.

Step 3: Turn on your wireless keyboard and mouse.

Press the power button on the right side of your Apple Wireless Keyboard and slide the switch on the bottom of your Apple Magic Mouse to turn them on.

Your wireless keyboard and mouse come with AA batteries installed, and they're already paired with your iMac. Pairing allows them to communicate wirelessly with your iMac.

When you first turn on your keyboard or mouse, the indicator light glows steadily for 5 seconds, indicating the batteries are good. If your keyboard or mouse doesn't turn on, make sure batteries are installed properly (see page 47).

The indicator light blinks until you turn on your iMac and a connection is established.

Note: If you purchased a USB keyboard or a USB mouse, connect the cable to a USB (P) port on the back of your iMac.

Step 4: Press the power (U) button on the back to turn on your iMac.

You hear a tone when you turn on your iMac. Click your mouse to establish a connection with your iMac.

Important: If your keyboard and mouse aren't paired with your iMac, follow the onscreen instructions to pair them. You may have to click the mouse once to establish a connection. For more information about pairing, see "Pairing Your Apple Wireless Keyboard with Your iMac" on page 27.

Step 5: Use Setup Assistant to configure your iMac.

The first time you turn on your iMac, Setup Assistant starts. Setup Assistant helps you enter your Internet and email information and set up a user account on your iMac. If you already have a Mac, Setup Assistant can help you automatically transfer files, applications, and other information from your previous Mac to your new iMac.

If you don't intend to keep or use your other Mac, it's best to deauthorize it from playing music, videos, or audiobooks that you've purchased from the iTunes Store. Deauthorizeing a computer prevents any songs, videos, or audiobooks you've purchased from being played by someone else and frees up another authorization for use. For information about deauthorizeing, choose iTunes Help from the Help menu in iTunes.

If you don't use Setup Assistant to transfer information when you first start up, you can do it later using Migration Assistant. Go to the Applications folder, open Utilities, and double-click Migration Assistant.

After you're set up, check for updated software. Choose Apple () > Software Update from the menu bar and follow the onscreen instructions.

Step 6: Customize your desktop and set your preferences.

You can easily make your desktop look the way you want using System Preferences, your command center for most settings on your iMac. Choose Apple () > System Preferences from the menu bar, or click the System Preferences icon in the Dock. For more information, open Mac Help and search for "System Preferences" or for the specific preference you want to change.

Putting Your iMac to Sleep or Shutting It Down

When you finish working with your iMac, you can put it to sleep or shut it down.

Putting Your iMac to Sleep

If you'll be away from your iMac for less than a few days, put it to sleep. When your iMac is in sleep, its screen is dark. You can quickly wake your iMac and bypass the startup process.

To put your iMac to sleep, do one of the following:

• Choose Apple () > Sleep from the menu bar.
• Press the power (U) button on the back of your iMac.
• Choose Apple () > System Preferences, click Energy Saver, and set a sleep timer.
• Hold down the Play/Pause () button on the optional Apple Remote for 3 seconds.

To wake your iMac from sleep, do one of the following:

• Press any key on the keyboard.
• Click the mouse.
• Press the power (U) button on the back of your iMac.
• Press any button on the optional Apple Remote.

When your iMac wakes from sleep, your applications, documents, and computer settings are exactly as you left them.

Shutting Down Your iMac

If you won't be using your iMac for more than a few days, shut it down. Choose Apple (●) > Shut Down. To turn your iMac on again, press the power (U) button.

NOTICE: Shut down your iMac before moving it. Moving your iMac while the hard disk is spinning can damage the hard disk, causing loss of data or an inability to start up from the hard disk.

• Unbuffered and unregistered

WARNING: Apple recommends that you have an Apple-certified technician install memory. See "AppleCare Service and Support" on page 58 for information about how to contact Apple for service. If you attempt to install memory and damage your equipment, that damage isn't covered by the limited warranty on your iMac.

Installing Memory

Your iMac has four memory slots. Two are filled with at least a 2 GB memory module. You can install additional memory in the free slots or replace the memory in the filled slots with 2 GB or 4 GB memory modules, for up to 16 GB of memory.

You can purchase additional Apple memory from an Apple Authorized Reseller, an Apple Retail Store, or the Apple Online Store at www.apple.com/store.

WARNING: Always shut down your iMac and remove the power cord before installing memory. Do not attempt to install memory while your iMac is plugged in.

To install memory:

1 Turn off your iMac by choosing Apple (串) > Shut Down
2 Disconnect all cables and the power cord from your iMac.
3 Place a soft, clean towel or cloth on your work surface. Hold the sides of your iMac and lay it down so that the screen rests on the surface and the bottom faces you.

4 Raise the stand and use a Phillips #2 screwdriver to loosen the three captive screws on the memory access door. Turn them counterclockwise.

5 Remove the memory access door and set it aside.

6 Untuck the tabs in the memory compartment.
7 To replace memory modules, pull the tab to eject the installed memory module. Remove the memory modules you want to replace.

2 When you see the Mac OS X desktop, choose Apple () > About This Mac.

You'll see the total amount of memory installed in your iMac. For a detailed view of the amount of memory installed, open System Profiler by clicking More Info.

If the memory you installed doesn't meet specifications (see page 36), your iMac will sound three tones every five seconds. If this happens, shut down your iMac and check the installation instructions again to make sure that the memory is compatible with your iMac and that it's installed correctly. If you still have problems, remove the memory and consult the support information that came with the memory or contact the vendor who provided the memory.

Problem, Meet Solution

Occasionally you may have problems while working with your iMac. Read on for troubleshooting tips to try when you have a problem. You can also find more troubleshooting information in Mac Help or on the iMac Service & Support website at www.apple.com/support/imac.

If you experience a problem working with your iMac, there's usually a simple and quick solution. If you encounter a problem, try to make a note of what you did before the problem occurred. This can help you narrow down the possible causes of the problem and then find the answers you need. Things to note:

• The applications you were using when the problem occurred. Problems that occur only with a specific application may indicate that the application isn't compatible with the version of Mac OS X installed on your iMac.
• Any software that you recently installed.
• Any new hardware (such as additional memory or a peripheral) that you connected or installed.

WARNING: Do not attempt to open your iMac, except to install memory. If your iMac needs service, see "Learning More, Service, and Support" on page 57 for information about how to contact Apple or an Apple Authorized Service Provider for service. Your iMac doesn't have any user-serviceable parts, except the memory.

Problems That Prevent You from Using Your iMac

If your iMac won't respond or the pointer won't move

• Make sure your Apple Wireless Keyboard or Apple Magic Mouse are turned on and the batteries are charged. (See "Replacing the Batteries" on page 47.) If you're using a USB keyboard or mouse, make sure they're connected. Unplug and then plug in the connectors and make sure they are secure.
• Try to force problem applications to quit. Hold down the Option and Command (36) keys and 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 your iMac to be sure the problem is entirely cleared up.
• If you're unable to force the application to quit, hold down the power (按钮 on the back of your iMac for five seconds to shut down the computer. Unplug the power cord from your iMac. Then plug the power cord back in and press the power (按钮 on your iMac to turn it on.

If the problem reoccurs when you use a particular application, check with the application's manufacturer to see if the application is compatible with your iMac.

For support and contact information about the software that came with your iMac, go to www.apple.com/guide or to the manufacturer's website.

If the problem occurs frequently, try reinstalling your system software (see "Reinstalling the Software That Came with Your iMac" on page 54).

If your iMac freezes during startup or you see a flashing question mark

• Wait a few seconds. If your iMac doesn't start up after a delay, shut down your iMac by pressing and holding the power (U) button for about 5 seconds, until it shuts down. Then hold down the Option key and press the power (U) button again to start up your iMac. Keep holding down the Option key until your iMac starts up, then click the arrow under the icon of the startup disk you want to use.
• After your iMac 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 iMac" on page 54).

If your iMac won't turn on or start up

• Make sure the power cord is plugged into your iMac and a functioning power outlet.
• Press the power (U) button and immediately hold down the Command (R), Option, P, and R keys until you hear the startup sound a second time. This resets the parameter RAM (PRAM).
• If you recently installed memory, and your iMac sounds tones every five seconds, make sure that the memory is correctly installed and that it is compatible with your iMac. Check whether removing the memory you installed allows your iMac to start up (see page 42).
• Unplug the power cord and wait at least 30 seconds. Plug the power cord in again and press the power (U) button to start up your iMac.
• If you still can't start up your iMac, see "Learning More, Service, and Support" on page 57 for information about contacting Apple for service.

Replacing the Batteries

Your Apple Wireless Keyboard and Apple Magic Mouse each come with two AA batteries installed. You can replace them with alkaline, lithium, or rechargeable AA batteries.

Keep the battery compartment cover and batteries out of the reach of small children.

WARNING: When you replace the batteries, replace them all at the same time. Don't mix old batteries with new batteries or mix battery types (for example, don't mix alkaline and lithium batteries).

Using Apple Hardware Test

If you suspect a problem with your iMac hardware, use the Apple Hardware Test application to help determine if there's a problem with one of the computer's components, such as the memory or processor.

To use Apple Hardware Test:

1 Disconnect all external devices from your iMac, except a USB keyboard and mouse, if you use them. If you have an Ethernet cable connected, disconnect it.
2 Restart your iMac while holding down the D key.
3 When the Apple Hardware Test language chooser screen appears, select the language you want to use.
4 Press the Return key or click the right arrow button.
5 When the Apple Hardware Test main screen appears (after about 45 seconds), follow the onscreen instructions.

6 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the error code before pursuing support options. If Apple Hardware Test doesn't detect a hardware failure, the problem may be software-related.

If this procedure doesn't work, you can insert the Applications Install DVD that came with your iMac to use Apple Hardware Test. For more information, see the Apple Hardware Test Read Me file on the Applications Install DVD.

Problems with Your Internet Connection

Your iMac has the Network Setup Assistant application to help walk you through setting up an Internet connection. Open System Preferences and click Network. Click the "Assist me" button to open Network Setup Assistant.

If you have trouble with your Internet connection, you can try the steps in this section for your type of connection or you can use Network Diagnostics.

To use Network Diagnostics:

1 Choose Apple () > System Preferences.
2 Click Network and then click"Assist me."
3 Click Diagnostics to open Network Diagnostics.
4 Follow the onscreen instructions.

If Network Diagnostics can't resolve the problem, there may be a problem with the Internet service provider (ISP) you are trying to connect to, with an external device you are using to connect to your ISP, or with the server you are trying to access. You can try the steps in the following sections.

Cable Modem, DSL Modem, and LAN Internet Connections

Make sure all modem cables are firmly plugged in, including the modem power cord, the cable from the modem to your iMac, and the cable from the modem to the wall jack. Also check the cables and power supplies to any Ethernet hubs or routers.

Turn the modem off and on and reset the modem hardware

Turn off your DSL or cable modem for a few minutes, and then turn it back on. Some ISPs recommend that you unplug the modem's power cord. If your modem has a reset button, you can press it either before or after you turn the power off and on.

Important: Instructions that refer to modems do not apply to LAN users. LAN users might have hubs, switches, routers, or connection pods that cable and DSL modem users do not have. LAN users should contact their network administrator rather than an ISP.

PPPoE Connections

If you are unable to connect to your ISP using PPPoE (Point to Point Protocol over Ethernet), make sure you have entered the correct information in Network preferences.

To enter PPPoE settings:

1 Choose Apple () > System Preferences.
2 Click Network.
3 Click Add (+) at the bottom of the network connection services list, and choose PPPOE from the Interface pop-up menu.
4 Choose an interface for the PPPoE service from the Ethernet pop-up menu. Choose Ethernet if you are connecting to a wired network, or AirPort if you are connecting to a wireless network.

5 Enter the information you received from your service provider, such as the account name, password, and PPPoE service name (if your service provider requires it).
6 Click Apply to make the settings active.

Network Connections

Make sure the Ethernet cable is plugged into your iMac and into the network. Check the cables and power supplies to your Ethernet hubs and routers.

If you have two or more computers sharing an Internet connection, be sure that your network is set up properly. You need to know whether your ISP provides only one IP address or multiple IP addresses, one for each computer.

If only one IP address is provided, 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.

An AirPort base station can be used to share one IP address among multiple computers. For information about using an AirPort base station, check Mac Help or visit the AirPort website at www.apple.com/support/airport.

If you can't resolve the issue using these steps, contact your ISP or network administrator.

Problems with AirPort Wireless Communication

If you have trouble using AirPort wireless communication:

• Make sure the computer or network you are trying to connect to is running and has a wireless access point.

• Make sure you've properly configured the software according to the instructions that came with your base station or access point.

• Make sure your iMac is within antenna range of the other computer or the network's access point. Nearby electronic devices or metal structures can interfere with wireless communication and reduce this range. Repositioning or rotating your iMac might improve reception.
• Check the AirPort ( ) status menu in the menu bar. Up to four bars appear, indicating signal strength. If the signal strength is weak, try changing your location.
• See AirPort Help (choose Help > Mac Help, and search for "AirPort"). Also see the instructions that came with the wireless device for more information.

Keeping Your Software Up to Date

You can connect to the Internet and automatically download and install the latest free software versions, drivers, and other enhancements from Apple.

When you're connected to the Internet, Software Update checks to see if any updates are available for your computer. You can set your iMac to check for updates periodically, and then you can download and install updated software.

To check for updated software:

1 Choose Apple () > System Preferences.

Last, but Not Least

For your safety and that of your equipment, follow these rules for handling and cleaning your iMac and for working more comfortably. Keep these instructions handy for reference by you and others.

NOTICE: Incorrect storage or use of your computer may void the manufacturer's warranty.

Important Safety Information

WARNING: Failure to follow these safety instructions could result in fire, electric shock, or other injury or damage.

Proper handling Set up your iMac on a stable work surface. Never push objects into the ventilation openings.

Water and wet locations Keep your iMac away from sources of liquid, such as drinks, washbasins, bathtubs, shower stalls, and so on. Protect your iMac from dampness or wet weather, such as rain, snow, and fog.

Power The only way to disconnect power completely is to unplug the power cord.
Make sure you pull the plug, not the cord. Always unplug the power cord before opening your iMac to install memory.

Unplug the power cord (by pulling the plug, not the cord) and disconnect the ethernet cable or phone cord if any of the following conditions exist:

• You want to add memory
• The power cord or plug becomes frayed or otherwise damaged
• You spill something into the case
• Your iMac is exposed to rain or excess moisture
• Your iMac has been dropped or the case has been damaged
• You suspect that your iMac needs service or repair
• You want to clean the case (use only the recommended procedure described later)

Important: The only way to turn off power completely is to unplug the power cord. Make sure at least one end of the power cord is within easy reach so that you can unplug your iMac when you need to.

WARNING: Your AC cord has a three-wire grounding plug (a plug that has a third, grounding pin). This plug fits only a grounded AC outlet. If you are unable to insert the plug into an outlet because the outlet isn't grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet. Do not defeat the purpose of the grounding plug.

Power specifications:

Voltage: 100 to 240V AC
- Current: 4 A, maximum
Frequency: 50 to 60Hz

Hearing damage Permanent hearing loss may occur if earbuds or headphones are used at high volume. Set the volume to a safe level. You can adapt over time to a higher volume of sound that may sound normal but can be damaging to your hearing. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked. The louder the volume, the less time is required before your hearing could be affected. Hearing experts suggest that to protect your hearing:

• Limit the amount of time you use earbuds or headphones at high volume.
• Avoid turning up the volume to block out noisy surroundings.
• Turn the volume down if you can't hear people speaking near you.

High-risk activities This computer system is not intended for use in the operation of nuclear facilities, aircraft navigation or communications systems, air traffic control systems, or for any other uses where the failure of the computer system could lead to death, personal injury, or severe environmental damage.

If your iMac needs service, contact an Apple Authorized Service Provider or Apple for service. See "Learning More, Service, and Support" on page 57.

If you open your iMac or install items other than memory, you risk damaging your equipment. Such damage isn't covered by the limited warranty on your iMac.

Important Handling Information

NOTICE: Failure to follow these handling instructions could result in damage to your iMac or other property.

Operating environment Operating your iMac outside these ranges may affect performance:

• Operating temperature: 50^ to 95^ F( 10^ to35^ C)
• Storage temperature: -4^ to 116^ F (-20^ to 47^ C)
• Relative humidity: 5% to 95% (noncondensing)
  Maximum operating altitude: 10,000 feet (3048 meters)

Do not operate your iMac in areas with significant amounts of airborne dust, or smoke from cigarettes, cigars, ashtrays, stoves, or fireplaces, or near an ultrasonic humidifier using unfiltered tap water. Tiny airborne particles produced by smoking, cooking, burning, or using an ultrasonic humidifier with unfiltered water may, in rare instances, enter the ventilation openings of your iMac and, under certain conditions, result in a slight haze on the inside surface of the glass panel that covers the iMac display.

Turning on your iMac Never turn on your iMac unless all of its internal and external parts are in place. Operating the computer when parts are missing may be dangerous and may damage your computer.

Carrying your iMac Before you lift or reposition your iMac, shut it down and disconnect all cables and cords connected to it. To lift or move your iMac, hold its sides.

Using connectors and ports Never force a connector into a port. When connecting a device, make sure the port is free of debris, that the connector matches the port, and that you have positioned the connector correctly in relation to the port.

Using the optical drive The SuperDrive in your iMac supports standard 12 cm (4.7 inch) discs. Irregularly shaped discs or discs smaller than 12 cm (4.7 inches) are not supported.

Storing your iMac If you are going to store your iMac for an extended period of time, keep it in a cool location (ideally, 71^ F or 22^ C).

Cleaning Your iMac

Follow these guidelines when cleaning the outside of your iMac and its components:

• Shut down your iMac and disconnect all cables.
• Use a damp, soft, lint-free cloth to clean the exterior of your iMac. Avoid getting moisture in any openings. Do not spray liquid directly on your iMac.
• Don't use aerosol sprays, solvents, or abrasives.

Cleaning Your iMac Display

Use a clean, soft, lint-free cloth to clean the display.

To clean your iMac display, do the following:

• Shut down your iMac and disconnect all cables.
• Dampen a clean, soft, lint-free cloth with water only, and then wipe the screen. Do not spray liquid directly on the screen.

Cleaning Your Mouse

You may need to clean your mouse from time to time to remove dirt and dust that has accumulated. Use a lint-free cloth that's been lightly moistened with water. Don't get moisture in any openings or use aerosol sprays, solvents, or abrasives.

If you use a wired Apple Mouse with your iMac, hold the mouse upside-down and roll the scroll ball vigorously with a clean, soft, lint-free cloth, to help dislodge any particles that may interfere with proper scrolling.

Understanding Ergonomics

Here are some tips for setting up a healthy work environment.

Keyboard

When you use the 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.

Change hand positions often to avoid fatigue. Some computer users might 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.

Mouse

Position the mouse at the same height as the keyboard and within a comfortable reach.

Display

Arrange the display so that the top of the screen is slightly below 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 nearby windows. The stand lets you set the display at the best angle for viewing, helping to reduce or eliminate glare from lighting sources you can't move.

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 are 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.

You might have to raise your chair so that 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, use a footrest with adjustable height and tilt to make up for any gap between the floor and your feet. Or you can 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.
