You saved my evening - wanted to restore iOS 8 GM with OS X Yosemite Beta & iTunes crashed when iPad was in Restore Mode.

Just opened Xcode Beta 6 (the 1st Release made it as well) and then opened iTunes 12 and everything worked.

No uninstall of iTunes etc.

Thanks a lot!
 
Fixed it for me too - Installed Xcode 6 GM - launched it then launched iTunes and connected iPad and now it seems to be working
 
After you get iOS 8 GM installed on whatever device you're using, does it sync well with iTunes 12 and Yosemite PB2?
 
I can't get it to restore from my encrypted backup. It just doesn't show up in the list (my unencrypted iPad backup shows up)
