Hello everybody. I am looking to sell my 2010 MacBook Pro before the months end. I need to save up some money for a new Mac. My Pro: -Mid 2010 -2.53GHz Intel Core i5 -4GB DDR3 -NVIDIA GeForce GT 330M 256 MB -The OS is Mountain Lion (I have a developer preview) -The storage is 500GB and last: It is a 15" display I have had some problems with the computer freezing. I have to hold down the power button on multiple occasions. How much would I get for selling this? and what site (besides Ebay-I have no idea how to use it, lol) would be best? All answers are greatly appreciated. Thank you for your time.
