Tried the article from MacAddict, got the image, but when I try to login using Terminal ("Run Command", type "su", enter my password) it says "Process Exited - code 1" (yes, I triple checked my password). Is there a special root/super user password I need (I've only created one password since installation.)
The root password on mine is the original password that I entered when I first started OS X. However, later I went into the Multiple Users settings and changed my admin's password. This did not change the root password to match. Perhaps this is what's giving some people trouble? If you changed your password at some point, try accessing root with the original password.
Also, since I'm not great with a Unix command line, how do I change the root password? I do know the password, so I can login as root.
