Hey everyone So later today I am going to buy a used MacBook on Craigslist and I just wanted your advice. First off, any advice on buying a laptop off Craigslist? What tests should I run while I'm there to make sure everything is okay? Second am I getting a good deal, I searched for a while to find this, Mid 2010 unibody 15 inch 2.66GHz Intel Core i7 500 GB 4GB Ram Super Drive I am paying $750. Mac2Sell values it at $1270 I would GREATLY appreciate anyone's input. Thank you!
