Hey guys, I recently upgraded to mavericks from snow leopard and recently got a new MBP so i am giving my old one to a friend. I would like to wipe it clean to factory settings so that he can set everything up under his name. I am just confused on what exactly i will need to do as i am unsure if i need a mavericks copy or a snow leopard copy? Has anyone had this problem and if so, how did you solve? Thanks!
