If Apple TV still doesn't appear in the iTunes source list (below Devices) after you verify the above items, try these steps. After attempting each step, check the iTunes source list to see if Apple TV appears. When Apple TV appears in the iTunes source list, you can stop troubleshooting and continue configuring Apple TV.
1. Restart iTunes (quit or exit and then reopen iTunes).
2. Reconnect Apple TV to iTunes.
- Choose iTunes > Preferences (Mac) or Edit > Preferences (Windows), click Apple TV, and make sure "Look for Apple TVs" is selected.
- If Firewall is on in Mac OS X (in the Sharing pane of System Preferences), make sure iTunes Music Sharing is selected.
- Open iTunes on your computer.
- Select the Apple TV icon with "Click to set up" next to it in the Devices list.
- Enter the five-digit passcode from your TV screen.
If you are still having trouble, you can try to reset your equipment by unplugging power cords for the following:
- Apple TV
- Your TV
- Your wireless networking equipment or AirPort Base Station
- Your router from the power outlet
Wait thirty seconds and then plug everything back in again.
4. Restart your computer.
5. Rejoin the network (wireless) or restart your network router.
6. Reinstall iTunes.
- Get the latest version of iTunes.
- If you are having issues reinstalling iTunes for Windows, see Trouble installing iTunes or QuickTime software in Windows.
- If you are having issues reinstalling iTunes for Mac OS X, see Troubleshooting iTunes installation on Mac OS X.
7. Configure firewall software.
If you have Mac OS X 10.5 (Leopard), read this article for information on configuring Firewall. For Mac OS X 10.4 and earlier, make sure UDP port 5353 (Bonjour) is open on your firewall. If you use Windows Firewall, follow these steps. Otherwise, if you use other firewall software or hardware, check the software documentation on how to open UDP port 5353.
8. If you use Windows, try disabling services and startup items that may conflict.
9. If you are using a wireless connection, then try a wired connection via a network switch or router.
10. If the issue persists, try bypassing all other network devices and connect directly to the computer's Ethernet port.
