So I have a 13inch white macbook that I need to sell because I just upgraded to a MBP. The macbook does not have iLife or iWork on it and it is running leopard. I do not have the original disks for the macbook but I do a Mac Box Set (includes snow leopard upgrade, iWork and iLife 09). I am trying to wipe the HD essentially reformatting the computer by just deleted all my personal data of the computer. Is there a way I can reformat using the snow leopard disc I have? Any help would be appreciated, thanks.
