MacBooks are built with user experience in mind, offering sleek design and intuitive functionality. One such feature is the backlit keyboard, which comes in handy while working in low-light environments. If you’re new to macOS or your keyboard lighting isn’t functioning as expected, this step-by-step guide will show you how to turn on the keyboard light on your Mac, troubleshoot common issues, and make the most out of your keyboard backlighting settings.
1. Understanding the Backlit Keyboard Feature
Most modern MacBook models (MacBook Air and MacBook Pro) come equipped with backlit keyboards. These lights are not just a design perk—they help you type accurately when ambient lighting is poor, such as on flights, in dark rooms, or late at night.
Backlit keyboards automatically adjust brightness based on your environment, thanks to the built-in ambient light sensor. However, this behavior can be customized or manually controlled to suit your preferences.
2. Using the Keyboard to Adjust Backlight
macOS Ventura and Later:
Starting from macOS Ventura, Apple removed the traditional keyboard brightness keys from newer MacBook models (especially with the M1/M2 chip series). Instead, these settings are now accessed through the Control Center or System Settings.
Here’s how to turn on the keyboard light:
-
Click on the Control Center icon in the top-right menu bar (it looks like two switches).
-
Find Keyboard Brightness. If it’s not there, you may need to add it (more on this below).
-
Use the slider to increase the brightness. This will turn on the keyboard backlight.
Older MacBook Models (with Function Keys):
If your MacBook still has the traditional function keys (usually F5 and F6):
-
Press F6 to increase the keyboard brightness.
-
Press F5 to decrease or turn off the backlight.
You may need to press the Fn key together with F5/F6 depending on your system preferences.

3. Using System Settings to Control Keyboard Backlight
You can also control your keyboard lighting through System Settings:
On macOS Ventura or later:
-
Go to System Settings > Keyboard.
-
Scroll down to find the Keyboard Brightness option.
-
Use the slider to manually set your preferred level.
-
You can also enable “Adjust keyboard brightness in low light” for automatic lighting based on your surroundings.
-
Optionally, toggle “Turn keyboard backlight off after inactivity” to save battery life.
On macOS Monterey or earlier:
-
Navigate to System Preferences > Keyboard.
-
Adjust the brightness using the slider.
-
You can enable auto-brightness and inactivity timer here as well.
4. Adding Keyboard Brightness to Control Center (if missing)
If the Keyboard Brightness slider doesn’t appear in the Control Center:
-
Go to System Settings > Control Center.
-
Under “Keyboard Brightness,” switch it to “Show in Menu Bar” or “Show in Control Center.”
-
This makes it easy to access anytime from the top-right of your screen.
5. Troubleshooting Keyboard Backlight Issues
Sometimes, even after following these steps, the keyboard backlight won’t turn on. Here are some practical solutions:
Check Ambient Lighting
If you’re in a well-lit room, your Mac might automatically disable the backlight to save energy. Try moving to a darker environment and see if the lighting activates.
Restart Your Mac
A simple reboot can often resolve minor software glitches that affect the keyboard light.
Reset the SMC (System Management Controller)
The SMC controls hardware-level features, including keyboard lighting. Resetting it can fix persistent issues.
For Intel Macs:
-
Shut down your Mac.
-
Press Shift + Control + Option and the power button simultaneously for 10 seconds.
-
Release all keys and turn on your Mac.
For Apple Silicon Macs:
-
Shut down your Mac.
-
Wait 30 seconds.
-
Restart it (Apple Silicon models reset SMC automatically on reboot).
Update macOS
Sometimes, software bugs affecting hardware features are resolved through updates. Go to System Settings > General > Software Update and install any pending updates.
When to Seek Mac Repair Services
If none of the above works, there could be a deeper hardware issue, like a malfunctioning ambient light sensor or a damaged keyboard backlight. In such cases, it’s wise to visit an Apple-certified technician or a professional Mac Repair center to get it inspected.

6. Tips to Extend Keyboard Backlight Lifespan
-
Use Auto-Brightness: Let your Mac decide when lighting is needed to conserve energy.
-
Set Idle Timeout: Turning off the backlight when inactive helps save battery and extend the lifespan of the LEDs.
-
Keep Your Keyboard Clean: Dust and grime can interfere with backlighting. Clean regularly with a soft, lint-free cloth.
Knowing how to turn on and manage your keyboard light on a Mac can dramatically improve your typing experience in dark environments. Whether you prefer manual control or automatic brightness adjustments, macOS provides flexible options. And if something isn’t working right, simple troubleshooting or expert Mac Repair services can help restore the functionality.
By following this guide, you can make the most of your Mac’s keyboard lighting—enhancing productivity, comfort, and style at any hour of the day.
