visudo

Scroll through the configuration file until you see the following entry: Allows people in group wheel to run all commands

If the second line begins with the # sign, it has been disabled and marked as a comment. Just delete the # sign at the beginning of the second line so it looks like the following:

%wheel        ALL=(ALL)       ALL

Then save the file and exit the editor.
