For the millionth time, I upgraded macOS to the next major version (Monterey) and I had to search for how to re-enable password-less sudo’ing (don’t judge me.)

1. edit /etc/sudoers

    sudo visudo
   

2. Then find the admin group permission section:

    %admin          ALL = (ALL) ALL
   

3. Change to add NOPASSWD:

    %admin          ALL = (ALL) NOPASSWD: ALL
   

4. Profit until next year.
