Troubleshooting the Keyboard Light
Assessing Ambient Lighting Conditions
The MacBook Pro has an ambient light sensor that adjusts the keyboard backlight based on the surrounding light conditions. When in a well-lit environment, the keyboard light might not activate, which is normal. However, if you’re in a dim or dark environment and the backlight still doesn’t activate, there’s an issue to address.
System Preference Settings
Firstly, it’s essential to confirm that the brightness of your keyboard backlight is adjusted appropriately. There are moments when it’s set to a very low level, which can make it challenging to see.
A common reason for the keyboard light not working is a misconfigured setting in the System Preferences. Go to System Preferences > Keyboard and ensure ‘Adjust keyboard brightness in low light’ is ticked. If not, your MacBook Pro might not be adjusting the keyboard light automatically.
Here are the quick instructions to inspect and adjust the brightness levels for several MacBook and iMac models:
For MacBook (Air and Pro) and iMac Models released in 2020 onwards:
Locate and click the Control Center symbol, positioned in the upper-right section of the menu bar.
- Select Keyboard Brightness from the available choices.
- Enhance the brightness by moving the slider to the right.
For MacBook Air and iMac Models released in 2019 or earlier:
- Use the F5 and F6 keys on your keyboard to regulate keyboard brightness.
For MacBook Pro Models featuring a Touch Bar (2019 or earlier):
- On the Touch Bar, find the Control Strip on its right-hand side.
- Click the left arrow to reveal the expanded Control Strip.
- Elevate the keyboard brightness by clicking on the Increase Brightness icon.
Additionally, it could be possible that your keyboard backlight issues are due to the automatic dimming feature. If you suspect this might be the case, follow the steps below to disable this function:
- Activate Spotlight Search by hitting Command + Spacebar, input “System Preferences,” and hit Return.
- In the System Preferences interface, choose Accessibility.
- In the left-hand menu, scroll down and select Keyboard.
- At the bottom of the screen, click on the Keyboard Preferences button.
- In the ensuing Keyboard window, select the Keyboard tab.
- Deselect the option “Adjust Keyboard Brightness in Low Light,” then close the window and check if the issue is resolved.
Resetting the System Management Controller (SMC)
The System Management Controller (SMC) is responsible for many low-level functions on your MacBook Pro, including the keyboard light. If the SMC is misbehaving, it can lead to the backlight not working. Resetting the SMC can often resolve this. Follow these steps:
- Select Apple menu > Shut Down and wait for your Mac to power down.
- Simultaneously press Shift-Control-Option on the left-hand side of the built-in keyboard, along with the power button.
- Release all keys.
- Press the power button once more to restart your Mac.
Resetting the PRAM or NVRAM
If none of the aforementioned solutions seem to work, a last-resort measure could be to reset the PRAM or NVRAM on your Mac. These are small memory spaces that store particular settings, and resetting them often resolves various issues.
- Power down your Mac.
- Press the power button to turn it back on and immediately hold down the Option, Command, P, and R keys together.
- Continue holding these keys for roughly 20 seconds, then let them go.
- Your Mac should reboot, and hopefully, your keyboard backlight should now be functioning correctly.

If the above methods don’t restore your keyboard light, it’s time to consider professional help.
