Macos – “You are not in the sudoers file” error after running sudo command


I tried using a sudo command on my iMac to create a bootable version of Ubuntu, but when I run the command by pressing enter, I got the warning that the command might screw up my system, which I ignored.

I then received a message:

you are not in the sudoers file, the incident will be reported

and my Terminal window was then rendered useless, with the usual $ not appearing so that I could type my commands.

What in the world is "sudoers", why is this happening and how can I put a stop to it?

sudoers is the file that specifies which users are allowed to sudo.

You need to run sudo from an account that is Administrator of your Mac, not a regular user account. Change the association in System Preferences.
