"Your iCloud account couldn't be removed at this time"
I changed my email address, and so I went in and changed my Apple ID as well. iCloud panel on my Mac is still stuck on the old email address. I clicked on Sign Out and it told me: "Your iCloud account couldn't be removed at this time. Turn off all iCloud services and try again." How do I do that? All the check boxes are grayed out. I tried entering my password, but it rejected that. I changed my Apple ID password, but it won't accept the new one either. How the heck do I "Turn off all iCloud services and try again"?
