Apple user ID change
I've changed my Apple ID(email). Although when I sign into iCloud, it has all the new correct info, my MAC, iPhone & iPad show the old, and the Mac keeps asking for my password for the old ID. Now if I try to go into the old one, it says it's been disabled for security purposes. Ideas on how to fix this??
