Enable Low Power Mode on Mac via Command Line
If you are a Mac laptop user and you spend a lot of time at the command line, you may appreciate knowing that you can enable Low Power Mode on a Mac laptop through a terminal command.
Enabling Low Power Mode through the command line on a MacBook Pro, MacBook Air, and MacBook is the same end result as if you toggled Low Power on through the macOS Battery preferences, except of course that you never have to leave the comfort of the terminal. You can also enable Low Power Mode through the Terminal, then turn it off from System Preferences, or vice versa.
