Share This:

Are you having issues with your Mac Keyboard backlight not working? If so, you’re not alone. Many Mac users are having issues with their keyboard backlight not turning on or off when they expect it to. Fortunately, there are a few easy steps you can take to troubleshoot this issue.

First, make sure that the Keyboard backlit option is enabled in the BIOS. To do this, power off your computer and press the power button. Immediately start pressing the F2 key once per second until you reach the BIOS menu. From there, navigate to the “Advanced” tab and select “Keyboard Backlight” from the list of options. Make sure that it is enabled, then save your changes and exit out of the BIOS menu.

Next, navigate to Apple Menu > System Settings and click on Keyboard in the sidebar (you may need to scroll down). You should see an option titled “Turn keyboard backlight off after inactivity” on the right-hand side of the window. Click on the pop-up menu next to this option and choose a time (e.g., 1 minute or 5 minutes). This will ensure that your keyboard backlight turns off automatically when it is inactive for a certain period of time.

If these steps don’t work, your Mac might be experiencing hardware issues with its keyboard lighting system. In this case, we recommend taking your laptop to a certified repair shop or Apple Store for professional assistance.

We hope this guide has helped you troubleshoot any issues you may be encountering with your Mac Keyboard and its backlight settings!

Troubleshooting Tips for When Your Mac Keyboard Backlight Won't Work 1

Troubleshooting Mac Keyboard Lighting Issues

There could be a few reasons why your Mac keyboard isn’t lighting up. First, make sure that the keyboard brightness settings are correctly adjusted. Go to the Apple menu > System Preferences > Keyboard and make sure that the “Adjust Keyboard Brightness” option is turned on. If it is, then check to see if you have enabled the keyboard backlight inactivity timeout setting. This setting will turn off the backlight after a certain amount of time of inactivity. To enable this setting, go to Apple menu > System Preferences > Keyboard and click on the pop-up menu next to “Turn keyboard backlight off after inactivity” on the right and choose a time. Finally, check your Mac’s battery level as a low battery can also cause your Mac’s keyboard not to light up.

Troubleshooting a Non-Functioning Backlit Keyboard

If your backlit keyboard is not working, it may be due to a few different reasons. First, check the BIOS settings to make sure that the keyboard backlit option is enabled. If it’s not enabled, you can enable it by pressing the F2 key while powering on the computer.

Second, make sure your laptop has enough power. If your laptop is running on battery, try plugging in the power cord and see if that helps.

Third, check if there is a dedicated key on your laptop with a picture of a light bulb or keyboard illumination that you can press to toggle the backlighting on and off.

Finally, if none of these solutions work, you may need to replace your keyboard or consult a professional for further assistance.

Turning On the Keyboard Light on a Mac

To turn on the keyboard light on your Mac, start by clicking the Apple Menu in the top left corner of your screen. Then select System Preferences -> Keyboard. To enable the keyboard backlighting to turn on and off automatically, check the box next to Adjust keyboard brightness in low light. To adjust the backlight manually, press the F6 key to brighten your keys. You can also use a combination of F5 and F6 keys to dim or brighten your keys as desired.


After making sure the Keyboard backlit option is enabled in the BIOS, you can adjust the time for when your Mac keyboard backlight will turn off after inactivity by going to the Apple menu > System Settings, then clicking Keyboard in the sidebar. By setting this time, you can be sure that your Mac keyboard will remain illuminated when you need it and help reduce battery consumption when you don’t.
