Deauthorise Apple ID from the Mac App Store I have Xcode installed using an Apple ID that I want it to be detached from. How can I login to the Mac App store using a different Apple ID and then have Xcode reattached to the new account in order to be updated? Not too sure if Mac App store and iTunes are using the same Apple ID.
You will need to delete Xcode, sign out of the Mac App Store, sign in with the new ID and "buy" Xcode again from the Mac App Store.
