"This Apple ID is not valid or not supported."
On my MacBook Air, I get prompted to sign into a certain Apple ID. However, I have gone appleid.apple.com to change the password, and I get this "This Apple ID is not valid or not supported."
What can I do? I read that some apps are tied to the id that they were downloaded under. How do I determine which apps those are?
