Unable to sign into iCloud on my Mac

Logging into very old Mac OS X El Capitan v10.11.6's iCloud shows "Preferences Error -- There was an error in iCloud preferences."


Is Apple not supporting this old? :(


Thank you for reading and hopefully answering soon. :)

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.


Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.


To find out if it's system wide or user specific, try this...


Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.


Does it work in the new account?
