mac os x / icloud login just freezes...
My Mac Pro using OS X Version 10.11.6 El Capitan all of a sudden won't log into icloud - and also seems to have screwed up all my email passwords stored for use by the Mail program.
I wasn't doing anything unusual, just all of a sudden tried to make me enter my email passwords. And when I did, it didn't seem to do anything. After numerous attempts, it then started telling me I needed to relog into icloud. When I tried, said the password was wrong (even though I know for sure it wasnt) and then forced me to change it. So I did. I was able to log in using other devices, and even to this forum with the new password... However, now when trying to log into icloud through System Preferences -> Internet Accounts, its just frozen. The password prompt is up, and the little hamster wheel is just spinning and spinning. I can't even stop it, can't quit system preferences either.
I've even forced it to quit, logged out and back in, and when I go back into to enter my icloud password, same **** happens... AAARRRGGGHHH....
Anybody from Apple able to help please??
Mac Pro, OS X El Capitan (10.11.6)
