Can't sign out from iCloud. The OS X is quoting an obsolete Apple ID.
System Preferences>iCloud Box Message:
Your iCloud account couldn’t be removed at this time. Mail was unable to delete [obsolete Apple ID]. Relaunch Mail then sign out of iCloud again.
System Preferences>Internet Accounts shows iCloud as Inactive and is greyed out. Clicking on it the right-hand pane states:
This is not your primary iCloud account.
iCloud ??? [Details box]
[obsolete Apple ID]
Clicking on the Details box reveals another box with an iCloud icon and a iCloud heading followed by:
Apple ID: [CORRECT Apple ID]
Description [I can insert anything and it is accepted]
Any ideas how to get rid of my iMac's obsession with the [obsolete Apple ID] and allow me to interact with System Preferences/Internet Accounts & iCloud?
