By using commands in your Mac’s built-in Terminal app, you can quickly change settings you probably didn’t even know existed.
Some of these Mac settings are just shortcuts — you can enable them in the usual way, using the mouse. But Terminal makes things simple. Instead of opening the System Preferences app, then finding (or remembering) a setting you want to change, and then searching further until you actually find the right checkbox, you can just type (or paste) a command, then hit return.
Most of these are secret settings, though. They are impossible to change without Terminal. Let’s check them out.
