Hey guys, this is going to be my 1st and most likely my only post on these forums, but I was hoping I could get some help. My Sister wants to buy my old Macbook from me and I have no idea how much it is worth. Here are the Specs; MacBook 13 Inch Mid 2007 Processor - 2.16GHz Intel Core 2 Duo Memory - 2Gb 667 MHz DDR2 SDRAM Graphics - Intel GMA 950 64MB Software - Mac OS X Lion 10.7.5 (11G63) The Macbook is in very good condition. As I am going to be selling to a family member an estimate price is fine, and I will sell for it for cheap. So does anyone have a rough estimate on how much it is worth? Thanks!
