iTunes authorization with iPhone
The new Mavericks update (10.9.2) crashed my system so had to restore from Time Machine. Then when I had iTunes going and plugged in iPhone, I got a message that this iphone was not authorized for "copying" files from this computer so I would neet to Authorize. So I authorized just fine and the next window says "this computer is already authorized." But when that window is closed, the "not authorized" window comes back. Back and forth, nothing changes.
I tried:
1. Deauthorizing this computer then reautorizing
2. Turning off my iphone then restarting
3. Deleting the SC Info folder (according to the Apple Support web page)
None of this has worked.
Any suggestions?
Mac Pro, OS X Mavericks (10.9)
