Hello everyone. I am soon buying a used macbook, which will be my first ever mac computer. He's selling it for 1100$, and according to him, it has under 6 months of use. specs: Screen: 13.3" Processor: Cor. 2 DUO, 2.4 GHZ Memory: 4GB Harddrive: 250 GB Software: OS Léopard 10.5, Toast , Microsoft office 2008, many other programs and included this picture: http://img1.classistatic.com/cps/l/kj/09/4/29/236/r1/1325dck_20.jpeg What should I test once I get there to make sure his computer works perfectly fine? Also, does this macbook have the new trackpad that you can click on? On the box, I don't see a button under the trackpad. That would be pretty sweet.
