iphone cannot be synced. An internal device error occurred
I've had this problem before and was fixed, but not sure when and how. This window appeared this morning as I always connect my phone to my iMac. I manually tried to sync but this window appeared again. The iPhone "x" cannot be synced. An internal device error occurred.
iPhone 5s, OS X Mountain Lion (10.8.5), downloaded iOS 7.0.2
