How to Turn Off the Keyboard Lighting on Mac

Having a backlit keyboard can be rather convenient in helping users discern the different keys when working in dim or low-light environments. Many, however, may find the keyboard lighting to be yet another distracting factor. Not to mention that although the individual LEDs used to backlight the keyboard require very little power, under intense circumstances they can still exert a toll on the system's battery, especially if it is already running extremely low on energy. In that case, users might want to turn the keyboard lighting off.

1. Select the Apple menu and open 'System Preferences.
2. Select the 'Keyboard' pane.
3. Locate the 'Adjust keyboard brightness in low light' option and uncheck its box.
4. Start pressing F5, fn+F, or the appropriate button on the Touch Bar.
5. Keep pressing the button until the keyboard backlight turns off.
6. Close 'System Preferences.'

If you want to revert the process and turn keyboard lighting back on, the first steps are the same:

1. Go to 'System Preferences' from the Apple menu.
2. Open the 'Keyboard' pane.
3. Find the 'Adjust keyboard brightness in low light' and enable it.
4. Start pressing F6, or fn+F6, or the appropriate button on the Touch Bar until the backlighting switches on.
5. Close 'System Preferences.'
