**HAS ORIGINAL BOX** This MacBook was lightly used. I recently installed a new Hard Drive because of the old one was junk, so you will not have to worry about replacing any parts. I got this Mac with only 1 GB or RAM and upgraded it to 2 GB's a few months ago. I currently have Windows 7 Ultimate installed on it as well, but I will be deleting it upon selling. (Windows 7 runs incredible on this by the way)! The Core 2 Duo processor has some intense speed, and is still quicker than my desktop PC! I have Mac OS X Lion (Newest operating system) installed, and this summer it IS CAPABLE of being upgraded to the newest OS again, I already checked. I do have one problem with this laptop, which could be a very easy fix... sometimes upon moving around a lot, the laptop will freeze. If you shut it off and tap on it, it will work fine. I have never had a time where it has been unusable, but it does sometimes become a hassle.
