How to turn off the keyboard backlight on Mac automatically

If you would like the keyboard backlight of your MacBook Pro or Air to turn off after some time without activity, you can force the system to do this automatically.

This option only applies to the backlight of the keyboard, not the Mac screen, so it is different from simply fading out the screen without activity.

  1. From the Apple menu, choose System Preferences.
  2. Select Keyboard.
  3. On the Keyboard tab, check the box next to “Turn off keyboard backlight after 5s. inaction. “
  4. You can also set the time after which the backlight will turn off: 5 seconds, 10 seconds, 30 seconds, 1 minute, or 5 minutes.
  5. You can close the system settings.

Recall that this function does not apply to energy saving functions, like turning off the display without activity. It concerns only the keyboard backlight.

It is not known whether this function affects the battery consumption since the backlight of the keyboard already works very economically. However, it still consumes some energy, so you can notice a minimal difference.
