I can sign in through my apple id ending in @yahoo.com but the registered apple id in my mac ends in @icloud.com without me changing it. It has the same name though. I cannot sign out the id registered in my mac system preferences (it says the apple id is not active and i cannot even look it up at iforgot.apple.com) but i can access my apple id ending with @yahoo.com in apple id website, icloud website, itunes and app store.
