I'm just about to sell my macbook pro. I only had it a few months so it's pretty new. I bought it from Apple online and I didn't get a boot disk or anything like that. I want to know how i can reset it so other's can sign in and set there own passwords etc. At the moment when I want to install something my user name comes up and I've to enter my password. - I don't want to give this out. I can remove all the content off it by hand so thats no a problem.. its more the Admin password thing i'd like to change. thanks.
