It is frustrating to notice that the display brightness won’t cooperate while working on a MacBook Air. Whether it won’t adjust properly or seems lighter or darker than usual, dealing with an issue like this can seem daunting. Don’t worry; several potential solutions can help get your screen back to optimum brightness.

In this article, we’ll discuss the most likely causes of Macbook Air brightness not working and their corresponding solutions — so you can stop struggling and start appreciating a comfortable viewing experience once again.

Fixing MacBook Air Brightness

1. Check Automatic Display Brightness Settings

To check your automatic display brightness settings,

  • Open the System Preferences on your MacBook Air and select the Displays pane.
  • In this pane, you’ll be able to adjust your display brightness levels by either changing the slider bar or using the “Automatically adjust brightness” feature.
  • This will allow your laptop to automatically adjust its display brightness based on the ambient light in your environment.

You can also keep an eye out for any other settings that affect the overall brightness of your Mac’s display. Also, click here to learn about how to defrag your Mac.

2. Check Keyboard Function Key Settings

If adjusting the automatic display brightness setting of your Macbook Air didn’t resolve the issue, another potential solution is checking if any of the keyboard function keys are blocking or interfering with the laptop’s ability to increase its screen brightness. To do this,

  • Go to System Preferences > Keyboard and select “Use all F1, F2, etc. keys as standard function keys”.
  • Once selected, try increasing/decreasing your laptop’s screen brightness via its function keys and see if that resolves the issue.

3. Turn Off the Slightly Dim Display

If neither of these options works for you, then one potential workaround is to turn off the slightly dim display to get more accurate results when adjusting the screen’s brightness manually. To do this,

  • Open up System Preferences > Displays again and uncheck “Slightly Dim Display” to increase accuracy when manually changing screen brightness levels.

4. Restart MacBook

If none of these potential solutions have worked thus far, then a simple restart might be all it takes to resolve this issue for you. Restarting a MacBook Air can often clear up any temporary problems preventing its display from correctly increasing/decreasing brightness levels.

5. Reset SMC

If restarting doesn’t help resolve this issue, resetting a MacBook Air’s System Management Controller (SMC) could fix it for you. Resetting SMC is fairly easy and straightforward – just shut down your system entirely and press down the Shift + Control + Option + Power button on either side of the laptop at once for about 10 seconds until it resets itself.

After resetting SMC, reopen your system and see if it fixes your problems with screen brightness not working correctly on MacBook Air anymore.

6. Reset NVRAM (Non-Volatile Random Access Memory)

In some cases resetting Non-Volatile Random Access Memory (NVRAM) can also help fix problems such as incorrect screen brightness settings on a MacBook Air model device.

To reset NVRAM, shut down your device before pressing down Command + Option + P + R simultaneously while powering it back up again. Wait until you hear two startup sound chimes before releasing those buttons, which means NVRAM has been successfully reset now.

This should hopefully fix any incorrect display settings-related issues causing trouble with Macbook Air’s screen brightness not working correctly anymore.

7. Use Safe Mode

If you’ve ever had the experience of being unable to adjust the brightness of your MacBook Air screen and guess that it may have something to do with a rogue application, then safe mode can help. Safe mode offers a simple way to diagnose problems as most of your applications are disabled in this operating state, allowing you to isolate any issues at play.

This includes any software causing brightness-related problems – restarting your computer in safe mode will generally fix them immediately.

8. Update macOS

Last but not least, if none of these methods have resolved this problem, then updating macOS could solve this issue instead. Since newer versions sometimes include bug fixes specifically designed to address such problems with particular laptop models like MacBook Air devices.

Where their displays tend to have difficulty adjusting their brightness levels properly in certain lighting conditions or environments unless they’re running with the latest possible version available at all times.

Make sure that you’ve recently updated macOS as much as possible before attempting any further troubleshooting steps that might be needed here – doing so could save you lots of time & effort along the way.

Final Thoughts
