Last night I tried to sync my iPad mini to my MBP through iTunes and after it went through it's usual process a message popped up saying "sync failed to finish". I'm running iTunes 12.1.26 and using the latest OS X beta. I had zero issues synching my/families other devices (iPod nano, iPod touch, iPhone 6, iPad 3). Also, I had no trouble synching the iPad mini several times on the same OS X beta until last night. It just happened out of the blue. I updated to the most recent iOS8 today as well as the newest OS X beta. Still no luck. Any ideas would be greatly appreciated.
