Hey everyone,
I have this issue in El Capitan as well, among other semi-related issues, if you're interested, here's a link to my other discussion about my issues which MAY OR MAY NOT be related (I don't know whether or not they are related): Apple ID on El Capitan does not work at all
Do any of you happen to have TWO-STEP VERIFICATION (AKA two-factor authentication or what ever you want to call it) on your Apple ID?
DO please read my thread as you may find some similarities in issues. Of course you can and should also try the steps people wrote in my thread as they may be helpful.
NOw, here's a somewhat unrelated question and I apologize for this in advance: for those of you who have tried to sign out of your iCloud accounts, specifically by going to system preferences>iCloud> sign out, you should have received a pop up that said something to the point of "warning: if you sign out of iCloud, all iCloud documents will be deleted from your Mac."
I am scared of signing out which may fix my issue because I am scared that my files may be deleted from iCloud. Did anything happen to your files after you signed out of iCloud?
side note: I once signed out of iCloud and almost lost all my keychain passwords, that's why I have a deathly fear of signing out of stuff. Long story.
THank you for your help, and forgive me for the random capitalization errors in this post. I am typing on my ipad which doesn't play nice with this discussion forum.
