    my suggestion would be to reinstall mac os x from scratch. boot into recovery, erase your hard drive, reinstall mac os x.

    Yes. ALWAYS format a used computer. What if he had installed a keylogger (know it's far out) or something.

    So boot into recovery and start from scratch.

    From Apple themselves: http://support.apple.com/kb/ph11273

    Your 'startup disk' they refer to will likely be called Macintosh HD (or something similar).

    You should reinstall OS X. At least, I would. But then again, I've never sold a laptop without wiping the hard drive first.

    I would still strongly suggest you to reinstall the whole thing! There is definitely much more of the previous owner's data left on the machine.

    Data that in theory can become a security breach. You don't know what this guy have had installed/surfed online. So please format.

    It takes one hour, and your Mac will be brand new.
