I recently received my brothers old Macbook 3,1. Its running OSX 10.5.8. Forgive my ignorance, I know nothing at all about Macs. Always been a PC user. Im trying to format this computer as it is very cluttered but I have no idea how to get started... Am I formatting the HD the same way I would with a PC? Ive tried finding information on this macbook and what it can handle but am seeing very different answers on the apple forum. Do I have any options for updating/upgrading? If so, what are they? Do I need a cd to do this? Ive tried finding tutorials on how to upgrade but they all seem to rely on a cd which I do not have. Any help is appreciated.
