More information about iChat AV is available in Mac Help. Choose Help > Mac Help, then choose Library > iChat AV Help. Understanding AirPort Extreme Wireless Networking Your iMac has built-in AirPort Extreme technology, which offers an easy and affordable way to provide wireless Internet access. AirPort uses wireless local area network (LAN) technology for wireless communication between multiple computers. You can access the Internet, transfer files, play multiplayer games, and more.
How AirPort Provides Wireless Internet Access With AirPort Extreme technology, your iMac makes a wireless connection to an AirPort Express or AirPort Extreme Base Station, which is connected to the Internet via a telephone line or a DSL modem or cable modem. Note: You need an AirPort Express or AirPort Extreme Base Station and Internet access (fees may apply). Some Internet service providers aren’t compatible with AirPort. Range may vary with site conditions.
Connecting to an Ethernet Network Your iMac comes with built-in 10/100/1000 megabit per second (Mbps) Base-T (twistedpair) Ethernet networking capability for connecting to a network or to a cable modem or DSL modem. G Ethernet port (10/100/1000Base-T) Connecting to a network gives you access to other computers on the network. You may be able to store and retrieve information, use network printers, modems, and email, or connect to the Internet.
Using Audio Devices Your iMac comes with built-in stereo speakers, a headphone out/optical digital audio out (f ) port, and an audio in/optical digital audio in (,) port. Headphone Out/Optical Digital Audio Out Port You can connect external powered speakers, headphones, 5.1 surround systems, and other sound output devices to the headphone out/optical digital audio out (f ) port. The headphone port is also a S/PDIF stereo 3.5 mini-phono jack.
Audio In/Optical Digital Audio In Port You can connect external microphones or other audio equipment to the audio in/ optical digital audio in (,) port. The audio in port does not provide power to a connected device, so you must use self-powered devices. The audio in port is also a S/PDIF stereo 3.5 mini-phono jack. You can use a Toslink cable and a Toslink jack-to-miniplug adapter to connect a Digital Audio Tape (DAT) deck or digital instruments to input and mix your own music.
Connecting External Displays, Televisions, and Video Devices Your iMac has a mini-DVI video out (£) port that you can use with an adapter to connect an external DVI display, an external VGA display or projector, or a TV, video projector, or VCR. Refer to the following chart to find the right adapter for your needs.
To purchase an adapter, visit an Apple Authorized Reseller, an Apple Store retail location, or the online Apple Store at www.apple.com/store. To connect an external display or projector: 1 Turn on the external display or projector. 2 Connect the adapter to the video port on the external display or projector. 3 Connect the mini-DVI end of the adapter to the mini-DVI video out (£) port on your iMac.
Using High-Speed Universal Serial Bus (USB) 2.0 Your iMac comes with five USB (d) ports (three high-speed USB 2.0 ports on the back of the iMac and two USB 1.1 ports on the keyboard), which you can use to connect many types of external devices, including a printer, scanner, iPod, digital camera, game pad, joystick, keyboard, or floppy disk drive. USB makes it easy to connect a peripheral—and once you connect it, it’s ready to use.
Note: Apple has included software to work with many USB devices. When you connect a USB device, if your iMac cannot find the correct software, install the software that came with the device or check the manufacturer’s website for the latest software. Using Multiple USB Devices at the Same Time If all of your USB ports are being used and you want to connect more USB devices, you can purchase a USB hub.
Connecting FireWire Devices Your iMac has two FireWire 400 (H) ports. FireWire lets you easily connect and disconnect external high-speed devices—such as digital video cameras, printers, scanners, and hard disks. You can connect and disconnect FireWire devices without restarting your iMac.
Using FireWire Devices To use a FireWire device with your iMac, simply connect the device to the FireWire (H) port. Apple has already included software to work with many FireWire devices. When you connect a FireWire device, if your iMac cannot find the correct software, you can install the software that came with the device or check the device manufacturer’s website for the latest software. Note: The FireWire (H) port is designed to provide power for FireWire devices (up to a total of 8 watts).
Using Your Optical Drive The optical drive in your iMac is a Combo drive. Use the Combo drive to install software from CDs, play music from audio CDs, and play DVD movies. You can burn music CDs that can play in most CD players, and save documents or other digital files to blank CD-R and CD-RW discs using the Finder. Warning: The Combo drive in your iMac supports standard circular 12 cm discs. Irregularly shaped discs or discs smaller than 12 cm are not supported.
Inserting a CD or DVD Disc To use a CD or DVD disc, follow these steps: 1 Place the disc into the Combo drive with the label facing you. 2 When the icon for the disc appears on the desktop, the disc is ready to use.
Ejecting a Disc To eject a disc, do one of the following: Â Drag the disc icon to the Trash. Â Press and hold the Media Eject (C) key on the keyboard until the disc ejects. If you can’t eject the disc, quit any applications that may be using the disc and try again. If that doesn’t work, restart your iMac while holding down the primary button on your Mighty Mouse. Playing DVD Discs To play a DVD, insert the DVD disc. DVD Player opens and starts playing the disc.
Recording CD-R and CD-RW Discs You can record music on CD-R or CD-RW discs right from your iTunes library. To record music to a CD-R or CD-RW disc using iTunes: 1 Click the iTunes icon in the Dock. 2 Select the playlist you want to record. 3 Insert a blank disc. (For highest compatibility with CD players, use a CD-R disc.) 4 At the top of the iTunes window, click Burn CD. To copy your files and folders onto CD-R and CD-RW discs using the Finder: 1 Insert a blank disc in the Combo drive.
Securing Your iMac Use a locking cable and the built-in security slot to secure your iMac.
