Is your MacBook Air keyboard not lighting up, leaving you struggling to type in the dark? Don’t worry; you’re not alone. Many MacBook Air users have encountered this issue, but the good news is that it’s often an easy fix. In this comprehensive article, we’ll guide you through the steps to get your MacBook Air keyboard to light up, ensuring you can work or browse in comfort, even in low-light environments.
The Importance of Backlit Keyboards
Before we dive into the solutions, let’s discuss why backlit keyboards are essential for many MacBook Air users. A backlit keyboard illuminates the keys, making it easier to type in the dark or in low-light environments. This feature is particularly useful for:
- Those who work late at night or in dimly lit offices
- Frequent travelers who often find themselves working in hotel rooms or airports with limited lighting
- Students who prefer to study or work on assignments in the evening
- Anyone who wants to type comfortably in bed or on their couch without disturbing others
Troubleshooting Steps
Before we explore the solutions, let’s troubleshoot the issue to identify the root cause. Follow these steps to determine why your MacBook Air keyboard is not lighting up:
Check the Keyboard Brightness Settings
- Click the Apple menu and select System Preferences.
- Click on Keyboard.
- Ensure the Keyboard tab is selected.
- Look for the Keyboard Brightness section.
- Adjust the slider to increase the keyboard brightness.
If adjusting the keyboard brightness settings doesn’t solve the issue, move on to the next step.
Check for Debris or Dirt
Dirt, dust, or other debris accumulated under the keys can block the backlight. Try the following:
- Turn your MacBook Air upside down and gently shake it to remove any loose particles.
- Use compressed air to blow away any remaining debris.
- Dampen a cloth with water, but make sure it’s not soaking wet. Wipe the keys gently to remove any stubborn dirt or dust.
Solutions to Get Your MacBook Air Keyboard to Light Up
If the troubleshooting steps above didn’t resolve the issue, it’s time to explore other solutions.
Enable Keyboard Backlighting in System Preferences
Sometimes, the keyboard backlighting feature might be disabled. To enable it:
- Click the Apple menu and select System Preferences.
- Click on Keyboard.
- Ensure the Keyboard tab is selected.
- Check the box next to “Adjust keyboard brightness in low-light environments” or “Illuminate keyboard in low-light environments” (depending on your macOS version).
Adjust the Ambient Light Sensor
The ambient light sensor, located near the webcam, helps adjust the keyboard backlighting based on the surrounding light conditions. If the sensor is blocked or malfunctioning, the keyboard backlight might not work. Try the following:
- Ensure the ambient light sensor is not blocked by any objects, such as a webcam cover or a laptop skin.
- Clean the ambient light sensor gently with a soft cloth.
- Restart your MacBook Air to allow the sensor to recalibrate.
Reset the System Management Controller (SMC)
The SMC is responsible for managing various system features, including the keyboard backlight. Resetting the SMC can sometimes resolve the issue:
- Shut down your MacBook Air.
- Locate the following keys: Power button, Command (⌘) + Option (⌥) + Shift (⇧) + Power button.
- Press and hold the keys while powering on your MacBook Air.
- Release the keys when you hear the boot chime for the second time.
- Let your MacBook Air boot up normally.
Reset the NVRAM and SMC
If resetting the SMC alone doesn’t work, try resetting both the NVRAM and SMC:
- Shut down your MacBook Air.
- Locate the following keys: Command (⌘) + Option (⌥) + P + R.
- Press and hold the keys while powering on your MacBook Air.
- Release the keys when you hear the boot chime for the second time.
- Let your MacBook Air boot up normally.
Check for macOS Updates
Ensure your MacBook Air is running the latest macOS version, as updates often include bug fixes and improvements:
- Click the Apple menu and select System Preferences.

Why does my MacBook Air keyboard not light up?
The MacBook Air keyboard is designed to automatically adjust its brightness based on the ambient light in your environment. If your keyboard is not lighting up, it’s possible that the ambient light sensor is not detecting sufficient darkness. Additionally, the auto-brightness feature might be disabled or set to a very low level. You can try adjusting the ambient light sensor or enabling auto-brightness to see if that resolves the issue.
Make sure to check your keyboard backlight settings in System Preferences > Keyboard > Keyboard tab. Ensure that the “Adjust keyboard brightness in low light” checkbox is selected and that the “Keyboard brightness” slider is not set to zero. You can also try adjusting the display brightness to see if it affects the keyboard backlight.
How do I turn on the keyboard light on my MacBook Air?
To turn on the keyboard light on your MacBook Air, you can use the keyboard shortcut F5 or F6. Pressing F5 will decrease the keyboard brightness, while pressing F6 will increase it. You can also adjust the keyboard brightness using the Touch Bar or by going to System Preferences > Keyboard > Keyboard tab.
Alternatively, you can use Siri to turn on the keyboard light. Simply say “Hey Siri, turn on keyboard light” or “Hey Siri, increase keyboard brightness.” If you have a MacBook Air with a Touch Bar, you can also tap the screen brightness icon in the Control Center and adjust the keyboard brightness from there.
Can I customize the keyboard backlight on my MacBook Air?
Yes, you can customize the keyboard backlight on your MacBook Air to some extent. You can adjust the keyboard brightness to your preferred level using the F5 and F6 keys or by going to System Preferences > Keyboard > Keyboard tab. You can also set the keyboard to automatically adjust its brightness based on the ambient light in your environment by enabling the “Adjust keyboard brightness in low light” feature.
Additionally, you can use third-party software or apps to customize the keyboard backlight. Some apps allow you to set custom keyboard brightness levels, adjust the backlight color, or even set up custom backlight profiles for different environments.
Why does my MacBook Air keyboard light keep turning off?
Your MacBook Air keyboard light might keep turning off due to various reasons. One common reason is that the ambient light sensor is detecting sufficient brightness in your environment, causing the keyboard backlight to turn off to conserve battery life. Another reason could be that the “Turn keyboard backlight off after [X] seconds of inactivity” feature is enabled.
To resolve this issue, you can try adjusting the ambient light sensor or disabling the “Turn keyboard backlight off after [X] seconds of inactivity” feature. You can do this by going to System Preferences > Keyboard > Keyboard tab and adjusting the corresponding settings.
Is it possible to set a custom keyboard backlight schedule on my MacBook Air?
Yes, it is possible to set a custom keyboard backlight schedule on your MacBook Air using third-party software or apps. While macOS does not provide a built-in feature for customizing the keyboard backlight schedule, you can use third-party apps to create custom profiles or schedules for your keyboard backlight.
For example, you can use an app to set the keyboard backlight to turn on or off at specific times of the day, or to adjust its brightness based on your daily routine. Some apps also allow you to create custom backlight profiles for different environments or activities.
How do I adjust the keyboard backlight on my MacBook Air with Touch Bar?
If you have a MacBook Air with a Touch Bar, you can adjust the keyboard backlight by tapping the screen brightness icon in the Control Center. From there, you can adjust the keyboard brightness slider to your preferred level. Alternatively, you can use the F5 and F6 keys to decrease or increase the keyboard brightness.
You can also go to System Preferences > Keyboard > Keyboard tab to adjust the keyboard brightness settings. From there, you can enable or disable the “Adjust keyboard brightness in low light” feature and adjust the “Keyboard brightness” slider to your preferred level.
Can I turn off the keyboard backlight on my MacBook Air completely?
Yes, you can turn off the keyboard backlight on your MacBook Air completely. To do this, go to System Preferences > Keyboard > Keyboard tab and move the “Keyboard brightness” slider all the way to the left. This will set the keyboard brightness to zero, effectively turning off the keyboard backlight.
Alternatively, you can use the F5 key to decrease the keyboard brightness until it turns off. Note that disabling the keyboard backlight can help conserve battery life, but it may also make it more difficult to type in low-light environments.
