How to Turn Off Auto Brightness on Mac

Is your Mac’s screen brightness automatically adjusting based on the ambient light conditions? This feature, known as Auto Brightness, can be useful in some situations but may not always be desired.

If you prefer to have full control over your Mac’s screen brightness, you can easily disable Auto Brightness with just a few simple steps. In this tutorial, we will guide you through the process of turning off Auto Brightness on your Mac.

Step 1: Open System Preferences

To begin, click on the Apple menu located in the top-left corner of your screen and select “System Preferences” from the dropdown menu. Alternatively, you can also access System Preferences from the Dock or by pressing Command + Spacebar and searching for it.

Step 2: Access Displays Preferences

In the System Preferences window, locate and click on the “Displays” icon. This will open up the Displays preferences panel where you can make adjustments to your Mac’s display settings.

Step 3: Disable Auto Brightness

Within the Displays preferences panel, navigate to the “Display” tab if it is not already selected. Here, you will find various options related to your display settings.

Note: Depending on your macOS version, this option might be located under a different tab or called something slightly different. However, it should still be relatively easy to identify.

Look for a checkbox or slider labeled “Automatically adjust brightness.” This is usually located towards the bottom of the Display preferences panel.

If the checkbox is selected or if the slider is turned on (indicating that Auto Brightness is enabled), click on it to disable this feature. Once disabled, your Mac’s screen brightness will no longer adjust automatically based on ambient light conditions.

Note: In some macOS versions, you may need to unlock the preferences panel by clicking on the lock icon at the bottom left corner and entering your administrator password before making any changes.

Step 4: Confirm and Close

After disabling Auto Brightness, take a moment to ensure that your desired screen brightness is set. Adjust the brightness manually by using the brightness keys on your keyboard or by dragging the brightness slider in the Display preferences panel.

Once you are satisfied with the screen brightness, close the Displays preferences panel. You have successfully turned off Auto Brightness on your Mac!

Troubleshooting

If you are unable to locate the “Automatically adjust brightness” checkbox or slider in your Display preferences panel, it could be due to several reasons:

  • Your Mac model may not support this feature.
  • You might be using an external display that does not have built-in support for Auto Brightness.
  • Your macOS version might have a different interface or settings organization.

In such cases, refer to Apple’s official documentation or search online for specific instructions tailored to your Mac model and macOS version.

In Conclusion

By following these steps, you can easily disable Auto Brightness on your Mac and regain control over your screen brightness settings. Whether you prefer a constant brightness level or want to manually adjust it according to your needs, turning off Auto Brightness allows you to customize your viewing experience. Enjoy using your Mac with just the right amount of brightness!
