I was just given a MacBook Pro by a friend who was over fiddling with it and just upgraded. It seems to have some sort of virus where most programs freeze, especially safari, after a few minutes use. It had a early version of snow leopard, but I upgraded to most current. Anyway, my goal is to restore it to factory conditions but with this model it seems you have to have the snow leopard DVDs to do so, which I do not. What I'm wondering is, is there an easier way to wipe it clean? Or should I just spend the $20 and get the DVDs ordered. OR is there a newer OS I can replace it with? I'm a PC user aside from my iPhone/iPad, so I don't know much about any of this!
