i recently bought a 2012 mac book pro and the previous owner gave me the log on credentials.However, the computer keeps asking for an administrators id and password when I tried to change the username to mine,. how can i fix that

You should be able to change all those in System Preferences -> Users & Groups. Make sure to unlock the settings on the bottom otherwise it will not let you change them, then right click on the admin's name and select 'Advanced Options...' . You can change everything there, name and passwords. Make sure to lock settings on the bottom again once you're done.

You can't get rid of the administrator name when you have not logged in with it. Return this mac.
