How to Change Screen Brightness on the Mac with Siri Voice Commands
Just about every Mac has screen brightness adjustment buttons on their keyboard, but for Macs with Siri enabled you can also adjust and change screen brightness on a Mac display easily with Siri voice commands instead.
This can offer a quicker option to adjust display dimness and brightness for some Mac users, and voice commands offer an alternative approach to the keyboard adjustments and Display preference panel adjustment options.
Tell Siri “Make the Screen Brighter” on the Mac
Hit your keyboard shortcut to activate Siri (the default is holding down Option + Spacebar), then issue your voice command to increase the screen brightness.
The following type of voice commands to Siri will increase the display brightness on a Mac:
- Brighten the screen
- Make the screen brighter
Tell Siri “Make the Screen Dimmer” on the Mac
Press your keyboard shortcut to activate Siri, then issue the appropriate voice command to adjust down the screen brightness.
These voice commands to Siri will decrease the screen brightness on the Mac:
- Make the screen darker
- Dim the screen
Making the screen darker or brighter is just one of many commands that Siri can do (and yes it works on the Mac as well as iOS).You can find many other helpful Mac Siri commands with this list here, and query Siri directly for command ideas too.
It’s worth mentioning that if you turned off MacBook auto-dimming that adjusting the screen brightness won’t change itself again if the ambient lighting situations change, so you’d need to adjust it again on your own through Siri or otherwise.
Some Siri Brightness Adjustment Commands Don’t Work
Interestingly enough, not all Siri commands work to adjust screen brightness on the Mac, and some that do not work currently include anything too vague or too specific, like the following:
- Change Screen Brightness
- Set screen brightness to 50%
There’s currently no way to make the incremental adjustments to brightness and volume like you can with the keyboard and slider approach, but
Is this faster than simply hitting the screen brightness adjustment buttons on Mac keyboards? Probably not for most users, unless perhaps you have a Touch Bar Mac where the virtual function buttons can be buried under app specific virtual buttons, but it’s really up to you and how you use your computer.
