Purchased 50 GB iCloud backup for iPhone xr. Wanted for phone only, now it backed up my iMac too which already has a hard drive backup attached. Because of it somehow backing up iMac it went over 50 GB and has locked up my email holding me hostage to upgrade again. How do I stop iCloud backup on the iMac but not the iPhone?
iCloud does not back up a Mac. Rather, you are likely syncing files through iCloud Drive. You can turn it off at System Preferences > Apple ID > iCloud
Thank you for your advice, it worked!
