Enable root on Mac OS X
The easiest way to do so is the following:
Login with an administrative priviledged account and open a Terminal and type:
username$ sudo passwd root
First provide the password of the administrative priviledged account (this is for sudo). Then write twice, as usual on passwd, a password for root.
From this point and on, you can use the root user as usual you use this priviledged account on any other UNIX.
My configuration, now that I have root enabled is the following.
My daily user is not an Administrator (not even in the sudo list). I have another Administrator account with administrative priviledges (e.g. it is in the sudo list), and now I have root enabled for the special cases I need that user.
