Change your Mac display’s brightness
You can adjust the display’s brightness manually or automatically.
Use the brightness function keys
If the screen seems too light or too dark, you can adjust your display’s brightness.
On your Mac, press the increase brightness key 
or the decrease brightness key 
(or use the Control Strip).
Automatically adjust brightness
If your Mac has an ambient light sensor, choose Apple menu
> System Preferences, click Displays, then click Display.
Select “Automatically adjust brightness”.
If you don’t see the “Automatically adjust brightness” tickbox, you can manually adjust the brightness.
Manually adjust brightness
On your Mac, choose Apple menu
> System Preferences, click Displays, then click Display.
Drag the Brightness slider to adjust the brightness of your display.
Depending on the type of display connected to your Mac, you may also see a Contrast slider that you can use to adjust the display’s contrast.
You can’t adjust the brightness of some older Apple displays. In OS X 10.10 and later, the Brightness slider may no longer appear in the Display pane of Displays preferences.
For specific information about the brightness of your display, check the documentation that came with your display.

Command-line display brightness control for macOS.
This tool enables you to set and obtain the brightness level of all internal and certain external displays from the command line or a script.
| If you cannot control your display’s brightness from Displays System Preferences, you will not be able to do it with brightness. See this issue for more information and some potential other options. |

Install with Homebrew
brew install brightness
Install From Source
macOS Version Support
brightness requires OS X/macOS 10.8 or later — but go back in the commit history and you’ll find code compatible with older (Mac) OS X versions.
Through macOS 10.12.3, brightness uses documented APIs. It works on internal laptop displays. It doesn’t work on older Apple external LCDs which connect via DVI and USB. I don’t know if it works on newer external displays, such as Thunderbolt displays, because I don’t have any to test with. (Feedback welcome.)
As of macOS 10.12.4 with the introduction of Night Shift, the documented APIs fail to work correctly and Apple does not provide replacement APIs. Therefore, brightness uses an undocumented method to adjust brightness.
macOS 11 on M1/Apple Silicon Macs require yet another undocumented method to adjust brightness (thanks to @jtbandes).
Set 100% brightness: brightness 1
Set 50% brightness: brightness 0.5
Show current brightness: brightness -l

MonitorControl — for Apple Silicon and Intel
Controls your external display brightness and volume and shows native OSD.
Use menulet sliders or the keyboard, including native Apple keys!
Go to Releases and download the latest .dmg
- Control your display’s brightness, volume and contrast!
- Shows native OSD for brightness and volume.
- Supports multiple protocols to adjust brightness: DDC for external displays (brightness, contrast, volume), native Apple porotocol for Apple and built-in displays, Gamma table control for software adjustment (recommended for OLED), shade control for AirPlay, Sidecar and Display Link devices.
- Supports smooth brightness transitions.
- Seamlessly combined hardware and software dimming extends dimming beyond the minimum brightness available on your display.
- Synchronize brightness from built-in and Apple screens — replicate Ambient light sensor and touch bar induced changes to a non-Apple external display!
- Sync up all your displays using a single slider or keyboard shortcuts.
- Allows dimming to full black (advanced feature).
- Support for custom keyboard shortcuts as well as standard brightness and media keys on Apple keyboards.
- Dozens of customization options to tweak the inner workings of the app to suit Your hardware and needs (don’t forget to enable Show advanced settings in app Preferences).
- Modern, stylish and highgly customizable menulet reflecting the design of Control Control introduced in Big Sur.
- Simple, unobstrusive UI to blend in to the general aesthetics of macOS (even the menu icon can be hidden).
- Supports automatic updates for a hassle-free expereince.
- The best app of its kind, completely FREE (donations accepted) with the source code transparently available!
How to install and use the app
- Download the app
- Copy the MonitorControl app file from the .DMG to your Applications folder
- Click on the MonitorControl app file
- Add the app to Accessibility under System Preferences » Security & Privacy » Privacy as prompted (this is required only if you wish to use the native Apple keyboard brightness and media keys — if this is not the case, you can safely skip this step).
- Use your keyboard or the sliders in the app menu (a brightness symbol in the macOS menubar as shown on the screenshot above) to control your displays.
- Open Preferences. for customization options (enable Show advanced settings for even more options).
- You can set up custom keyboard shortcuts under the Keyboard in Preferences (the app uses Apple media keys by default).
- If you have any questions, go to Discussions!
| MonitorControl version | macOS version |
|---|---|
| v4.0.0 | Catalina 10.15* |
| v3.1.1 | Mojave 10.14 |
| v2.1.0 | Sierra 10.12 |
* With some limitations — full functionality available on macOS 11 Big Sur or newer.
Note to f.lux users: the app is now compatible with f.lux as well — please activate Avoid gamma table manipulation under Preferences » Displays (this option is accessible if advanced settings are enabled)! This is not needed if you use Night Shift.
Open issues if you have a question, an enhancement to suggest or a bug you’ve found. If you want you can fork the code yourself and submit a pull request to improve the app.
MonitorControl supports localization. We gladly welcome your contribution with a new language! See the opening post of the relevant discussion on how to add your translation!
- Xcode
- Swiftlint
- SwiftFormat
- BartyCrouch (for updating localizations)
- Clone the project via this Terminal command:
- If you want to clone one of the branches, add —single-branch —branch [branchname] after the clone option.
- You’re all set ! Now open the MonitorControl.xcodeproj with Xcode! The dependencies will automatically get downloaded once you open the project. If they don’t: File > Packages > Resolve Package Versions

Brightness Slider 4+

Description
With Brightness Slider you can adjust screen brightness from the menu
bar, just like the sound menu provided by Apple, and with improved
control over the dimming process.
Using a keyboard with no brightness keys? Tired of low brightness
levels which are still too bright? Brightness Slider gives you total
control over your screen’s brightness settings, allowing in
particular for a really smooth transition between low light and total
darkness.
Features:
— Screen brightness level adjustment right from the menu bar
— Dimming control at low brightness levels
— Arrow key function with active Brightness Slider menu
— Custom hotkeys for lowering and raising brightness levels
— Start at login option available in the preferences
How Brightness Slider works:
Brightness Slider darkens your display by combining two separate
methods. Method A adjusts the real backlight intensity of your
display and method B creates a semi-transparent black veil above
everything else. Why the complexity? Well, when dimming a display,
the final jump down to no backlight at all is very large, especially
in a darkened room. To provide more control over the dimming process,
the top-half of the slider controls the backlight intensity from 1
down to 0.1 (method A). Then, the bottom-half controls the opacity of
the semi-transparent veil, whilst keeping the backlight at 0.1
(method B). When the slider is at zero, the backlight is turned off.
The result is that the final jump now has several intermediate steps,
which means the perceived brightness (the combined result of both
methods) is that much more adjustable.
One last thing:
There are displays where Brightness Slider cannot control backlight
intensity. However, it can still perceptually dim the screen by
controlling the opacity of the semi-transparent veil (which can be
created on any display).
