Windows iCloud app not signing in after adding an iMac
Having a very strange issue.
I've been using the Windows iCloud utility for years to sync my iCloud email, calendars, contact with Outlook, and files and phones with Windows 11.
My wife just got a new M1 iMac and we both added our iCloud accounts to it. Since I added my account to the iMac, iCloud will not sign in on Windows and displays the error:
It does accept my AppleId and password, and prompts for the 2FA code which does succeed. I've tried removing the PC from my Apple ID, uninstalling iCloud app and reinstalling. Based on the message, it seems to think I'm signing in from the iMac. I also have a MacBook air under my Apple ID and there's no issue with that.
I also tried removing my account from the iMac, but the issue persists.
