My friend bought a seal MacBook Air from Craigslist last month. The person he bought it from told him got it about a month before. He was an army guy who told him he had credit in a store on line. He needed cash and that was the only way for him to get same money to fix his broken car. He did have the receipt with him. Today my friend and I went to the apple page, for curiosity we put in the serial # in the service and support search. It come up that it only has warranty until February of 2016. My understanding was that the warranty runs from the day you start using it which is the day that you register with Apple. Does he have any right to ask apple to change the warranty day? Does anybody know how this work? I will appreciate the feedback. Thank you all.
