Can not connect iPhone/music to new macbook iTunes
I just recently bought a new Macbook Pro with Retina Display, and am transfering over from a Macbook about 3 years old. My iPhone 4 when I plug it in to the new macbook will not connect with iTunes. It says that it does not have permission.
How do I give my old iphone permission on the new computer, to become its default.
Thanks
MacBook Pro (Retina, 13-inch, Late 2012), iOS 6.0.1, Iphone and itunes connection
