sorry i should have said his earlier, buti got this computer from a friend. he had WIN XP on it. when i have to press option at the start up to pic mac. i dont know how to take that off i want to. and for some reason. my user on here is an admin. but i cant change anything. so im think im kind of in a bind.
if i format the hard drive so i have to reinstall everythin like OS X?
because i just got this and ive been with windows my whole life. ive look everywhere and i need the admin username a password to even install something! >:[
