Cannot remove a second iCloud account from iMac (macOS 13.4)
I added a relatives iCloud email account to my iMac to give her a hand sorting an issue. That's now all done but I can't delete the account. I f I try to remove the account from the Mail/Calendar/Contacts apps I get a message saying the iCloud account is shared by other applications on this Mac and tells me to delete it from Internet accounts in system settings. When I try that it does delete for a few moments but then reappears.
I've gone through Keychain and deleted any reference to the account there but entries just restore themselves when the account reappears. I've trying booting into safe mode and deleting but still the same.
I've asked my relative to look on their iPhone, iPad etc to see if my device is mentioned - they did see it and delete it but that hasn't made a difference either.
Any suggestions before I have to erase and reload my Mac? It's a nuclear option I would like to avoid.
