I'm used to "classic" unixoid user right system with a machine running a normal user, as main account, and a super user (or root account), just for maintenance or configuration purposes.
Then I was really wondered about Mac OS X (I'm currently running Leopard). What purpose has the admin user account? If I'm installing something via console (as a normal user, not admin) I have apparently to log in as admin and then log in as root user (via
sudo -s because
su strangely doesn't work).
Does anyone know what the main reason for this is or how to fix it?
