Problem: Upgraded to 10.7.4 Lion...Now Aperture 3 won't show up on iTunes for AppleTV to sync Background: I have a AppleTV (160 GB) 2nd Gen. It's been no problem for me to sync Aperture3 library to it via the iTunes. I upgraded from Snow Lepoard to Lion about 4 weeks ago, part of that was the Aperture 3 upgrade and also the iTunes. Well, on my AppleTV (160 GB) 2nd Gen it syncs music fine, but the Aperture Library won't show I even re-set the AppleTV and totally thinking that might solve it, the music re-sync fine but Aperture 3 library won't even appear still. I'm at a loss of what to do. Some screen shots: Music sync ok Aperture 3 Library won't even show, it has over 30k photos and those prior were all sync to AppleTV: iPhoto does show, we only use this for calendars, nothing else, so those 483 aren't really sync to the AppleTV, just shows the library is available.
