System Preferences Frozen on Apple ID sign in
When I try to sign in with my Apple ID in my MacBook Pro System Preferences, I just see the spinning wheel at the bottom of the grey sign in box. I've entered the correct password but when I click next nothing happens, just a little click noise but wheel keeps spinning. Can't close System Preferences. Can't make updates or restart/shut down computer because I get message that System Preferences has stopped it. I've even tried clicking "forgot password" just to get me out of this but I just get that dead end click noise. Is there a fix to this?
MacBook Pro 15″, OS X 10.11
