Some of you might remember my thread around Valentines Day when I had to send my macbook pro into Best Buy for repairs because it wouldn't turn on, and they replaced my whole logic board. Today I decided to get around to signing back into iMessage and no matter what I tried nothing happened. After looking online I checked my about this mac and noticed my serial number says unavailable. I won't take my macbook back to Best Buy and the closest Apple store is atleast an hour away, is there any other option that I can get this fixed that doesn't involve mailing it in? Irritatingly there are 5 Apple stores all within 15 miles of eachother, but all ~60 miles from me.
