If you bought your mac used, dont bother bringing it here.  Was having issues with my macbook pro, so far had 2 conflicting ideas from 2 different sources.  they had to find the serial number, only to find that I had bought it used from another store because that's the only way I could afford one, they wont even diagnos it.  I know its vintage so they woulndt work on it but I guess they were afraid of getting cooties from it cause the wouldnt even touch it.  Fuck you. if I ever buy apple again, which admitedly I will, it will never be from you guys.  I will never buy anything from your store.
