I'm trying to sync my iPhone to my MacBook Pro. I connect the iPhone, launch iTunes, click on the device, then click "Sync".
I'm presented with this dialog:
I click "Authorize". Then I get this dialog:
I fill in the information and click "Authorize".
Then I get this dialog:
I click "OK" and instantly I am presented with the first dialog above, the one that says, "This computer is no longer authorized..."
Then it just enlessly cycles between those three dialogs, never letting me authorize the computer.
Mac OS 10.7.3
iTunes 10.6.1 (7)
