**Why is my keyboard brightness not working on Mac?**

The brightness function on your Mac keyboard not working can be quite frustrating. However, there are several possible reasons why this issue may arise, and fortunately, most of them can be easily resolved.

One common reason why your keyboard brightness might not be working on your Mac is due to a software glitch. The first step you can take is to restart your Mac and see if the issue persists. Often, a simple restart can fix minor software problems.

If restarting your Mac doesn’t resolve the issue, you can try resetting the NVRAM or PRAM. These are small pieces of memory that store certain settings on your Mac, including keyboard brightness. Resetting them can help resolve the issue. To do this, restart your Mac and hold down the Command (⌘), Option, P, and R keys until you hear the startup sound for the second time.

Another reason why your Mac’s keyboard brightness may not work is because you have a third-party application or software conflicting with your keyboard settings. Check if you have any third-party applications installed that might be controlling keyboard features or have remapped the keys. Try quitting those applications or uninstalling them to see if it fixes the issue.

If you recently updated your macOS, it is possible that the update caused a compatibility issue with your keyboard’s brightness settings. Ensure that you have the latest macOS update installed on your Mac, as subsequent updates often include bug fixes and improvements that address such issues.

If the above solutions don’t work, it is worth checking your keyboard settings manually. Open System Preferences and select “Keyboard.” Go to the “Keyboard” tab and ensure that the “Adjust keyboard brightness in low light” option is checked. Also, make sure the “Illuminate keyboard in low light conditions” option is enabled. Adjusting these settings may solve the problem.

Sometimes, a physical issue with your Mac’s keyboard can prevent the brightness function from working. Check your keyboard for any debris, dirt, or liquid spills that may be interfering with the keys. Clean the keyboard gently using compressed air or a soft cloth to remove any obstructions. If the issue persists, you might need to have your keyboard repaired or replaced.
