Within System Preferences > Keyboard > Keyboard, you can also configure how long you’d like the backlight to stay on after your Mac stops being used. To change the brightness level of this afterward, again you can use the proper function keys (usually F5 and F6) or the controls on your Touch Bar, which look like…um…little sunrises? Of which the smaller one makes the backlight dimmer? These things are hard to describe, my friends. To do that, visit Apple Menu > System Preferences > Keyboard, and under the “Keyboard” tab, deselect “Adjust keyboard brightness in low light.” If you’ve got a laptop where the keys glow a bit, you can again either let the Mac decide how bright to make that glow or force it to stay at a brightness level you specify. Those function keys are usually F1 and F2, but you’ll note they’re the ones with the sun icons on them.įinally, there’s one more way to disable auto-brightness functionality-by doing so for your backlit keyboard. Once you deselect that option, your screen will no longer brighten or dim without your say-so! Of course, you can manually adjust that setting either from this same System Preferences > Displays > Display pane using the “Brightness” slider shown above, or you can use the appropriate function keys (or the Touch Bar) on your keyboard. Under the Display tab there, deselect the Automatically adjust brightness option.

Click on the Apple Menu at the upper-left corner of your screen and choose System Preferences.
