Ok so first off I want to thank you for any help.. I bought a 13 in macbook pro for my finace and I can't get it up and running. I bought it from an older person who can't remember the password to the account. I started up in single user mode and finally created a new account and set a new password but I still dont think it it the master account. I cant get the mac to boot up, a gray screen comes up that says restart computer in a bunch of different languages. I have the OSX disk in the cpu. What i would like to do is try to wipe it completely from single user mode if i can and then just re install OSX. The previous owner tried to wipe it to clear their stuff and it's now a mess. I have no idea what to do and my fiance is getting mad that I can't get it working after spending that money. Please someone help!!!
