How to Run GUI Apps as root in Mac OS X Feb 6, 2013 - 10 Comments Those familiar with the command line know that running things with super user privileges is typically just a matter of using the sudo command.

command gives you an error:
This is because the shutdown
command can be run only by the root user or by an administrator user with root user privileges.
To run commands with superuser privileges, use the sudo
command. sudo
stands for superuser do.

If a command requires it, you can use su
to switch to the root user. Under normal circumstances, you shouldn’t log in as the root user.

to log in as the root user, be especially careful, because you have sufficient privileges to make changes that can cause your computer to stop working.
