I have been synching my 4S with iTunes for the past week and now I am getting messages that my Macbook Pro is no longer authorized for the apps and it gives me the option to authorize them. I click yes and it asks me for my password, it then tells me that the Mac is authorized, I click ok and then it pops up again saying it is not authorized, and I do the same thing, it pops up again, and again. What is going on? Attached are screen grabs.
