I'm trying to sell my macbook (4,1)...I don't want to but I need the money Anywho, I'm trying to wipe out the data on the hard drive but I'm afraid this means that all my other installed programmes will be wiped out with it. I have mac office 2011 and iLife and all that BUT I have no disk. My mac runs mac os x lion. Is there anyway I can do this without having to purchase all the software as it'll just increase what I have to spend/decrease my price? And sorry if this seems like a n00by questions. My macbook 4,1 is my first and only mac which I got about a month ago.
