Okay so I have read many posts on here where people have a problem with their mac and are told to take it in for repair at an apple store. In most of these posts someone will mention expensive repairs. So I have a question about Apple care, does it basically cover anything that is not accidental or intentional damage? And will I have to pay a portion of a repair in case I need to have something repaired or do I just pay the cost of apple care up front and no further fees?
