OK so I got this G4 ibook from a friend that hasn't used it in a while and just wanted to get rid of it. I needed a laptop for school so he sold it to me pretty cheap but he doesn't know the admin account name or password. I'm new to macs by the way. I understand that if you have the install disc you can reset the password through it but he doesn't have any discs either. Would the version matter? I'm thinking about just buying a new copy but if it's a different version would that allow me to reset the password and the admin username? I guess if I bought a new copy I could just install fresh but just wondering if this is possible before I buy one. Thanks alot !
