I think guys the OP is legit, I checked his all past posts and seems that he had (Not sure if he still has) the same macbook pro, https://bitcointalk.org/index.php?topic=1235104.msg12858587#msg12858587 and since the OP is accepting escrow I think people should not be worried (if we are talking for the same macbook). OP can you confirm that this is the macbook that you are going to sell?
