Why don't I see Apple TV in the Source list in iTunes?
Why don't see the Apple TV (device) when I open iTunes?
iMac, Mac OS X (10.6.8), (1) 2.16 Ghz Intel Core, 3 GB, Airport extreme
What version Apple TV? Generations 2 and 3 (current) have no significant memory for iTunes to load to so these devices only show up in iTunes when connected by USB cable. With this in mind, please explain what you mean when you say it doesn't show up in iTunes.
