Hi, I just have a quick question. If I were to buy a new Mac from the Apple store, as well as auto-enroll in Apple Care, would it use the purchasing Apple ID to do these things? (The online store requires you log in or create an Apple ID.) Or, would you be able to input a different Apple ID upon setting up the computer yourself? I want to order a birthday gift for my son, but do not want to ask for his apple ID password to tip him off. Thanks!
