How to Disable Display, Keyboard Auto-Brightness on Your Mac


Here's how you can disable auto-brightness for the display and keyboard on your Mac. This is great if you love more manual control over your workspace.

Kick Things into Manual Mode by Disabling Auto-Brightness Feature for Display & Keyboard on Your Mac

Just like our iPhones and iPads, the Mac has a built-in auto-brightness feature that adjusts the brightness of the display (and keyboard as well) according on the available ambient light. While this feature is great to have, but it can get rather annoying to look at. Even if someone flashes a small light towards the display, the brightness will go right up, only to come down after a few seconds. The same goes for the keyboard as well. So, in order to overcome this annoyance, you can disable the auto-brightness feature altogether. That's exactly what we will be showing you how to do in today's guide.

Tutorial for Turning off Display Auto-Brightness

1. Launch System Preferences.

2. Now click on Displays.

3. Click on the 'Automatically adjust brightness' option to uncheck and disable it.

Whether you're sitting inside your blanket or on the beach, your Mac will no longer adjust the screen brightness on its own.

Tutorial for Turning off Keyboard Auto-Brightness

Note: This part is applicable for MacBook users only, since it's the only Mac with a backlit keyboard.

1. Launch System Preferences.

2. Click on Keyboard.

3. Click on 'Adjust keyboard brightness in low light' option to uncheck and disable it.

Once this option is disabled your MacBook will not trigger the keyboard backlighting once you enter a dark room. You will have to kick things up manually. Also, make sure to turn down the brightness of the keyboard in a brightly lit room. You want to conserve as much battery as possible. After all, you're in full manual control at this point.

I will even go as far as saying that you should leave keyboard backlighting in an automatic state. macOS and OS X are very smart when it comes to recognizing whether you need backlighting or not. But the final call rests with you whether or not you want to take that road.

Wrap Up

Automatic brightness feature on devices is very handy in different situations. Especially on mobile devices, where it can actually help you conserve a lot of battery life. But for some users though, this feature can turn into an annoyance. If you're one of those who think that way, then you're better off disabling the feature.
