Can't not sign in iTunes and AppStore
Dear all,
My problem is: when I Sign in my iTunes and AppStore, the loading window's still running until I shut down my Mac (OS X El Capitan version 10.11.1).
I still use this id to log in on my iPhone correctly. I shut down my Mac for many times but this problem still happens!
Any body has this problem like me? And there's someone who can fix it? Thank for reading and giving advice!
Best Regards!
Mac Pro, OS X El Capitan (10.11.1)
