How to change permissions for etc folder mac?
The /etc directory on a mac isn't a directory at all, it's a symlink (shortcut). It redirects to private/etc.

You won't be able to chmod the directory, because it belongs to the root user by default. If you want to chmod it you'll have to prefix the command with 'sudo' to run as the superuser.

Bearing that in mind, make sure you know what you're doing before you start playing around with system directories and their permissions.
