Running 11.1.3, and it did it before when 11 came out I think, whenever I hook up my iPad or iPhone and after I select music, movies, tv shows to put on the iPad/iPhone, it looks for the device but then can't find it. It's shown under Devices and even when I select the device, it shows everything about it, but it just loses it when I select Sync.
I have to then quit iTunes...but wait, iTunes says it stopped responding when I right click on the icon in the dock. So I have to force quit it. Which happens wayyyyy too much lately.
When I restart iTunes, it works fine, recognizing the devices and syncs. But that only lasts for probably a couple of days, never really kept track, but it's not that long.
Any ideas? trash the sync prefs?
