trying to logout of iCloud but keychain not allowing
I'm trying to logout from iCloud but cannot turn off keychain.
When I click on System Prefs/iCloud/ 'sign out' the following message appears:
I've tried both options, keep or delete, always same result:
Another approach is to turn off the checkmark against keychain, but that brings same result as above and the checkmark simply re-checks itself.
Any suggestions?
Thanks in advance.
