If you edit your /etc/host file on macOS or need to bind to a privileged port for local web testing then you’ll probably use sudo a lot. It can get really annoying having to constantly apply your password for each sudo command so just like in Linux we can disable the password prompt.
To do open up /etc/sudoers duplicate and uncomment the first %admin group entry
#%admin ALL = (ALL) ALL
and replace with:
%admin ALL = NOPASSWD: ALL
Now if you are a administrator on the local machine you should be able to use sudo with out any passwords. Horray!
