Lunar
Intelligent adaptive brightness for your external display.
Lunar overview
Lunar controls the same brightness that you can change by using the monitor's physical buttons.
- Sensor-based Adaptive Brightness (and contrast) based on an external light sensor
- Sync-based Adaptive Brightness (and contrast) based on the built-in light sensor of the Macbook or iMac
- Location-based Adaptive Brightness (and contrast) based on the sunrise/sunset times in your location
- App Exception list if you need more brightness for specific activities (watching movies, design work)
- Individual settings per display
- Manual controls and hotkeys for setting brightness and contrast that respect the min/max values per monitor
It doesn't interfere at all with the native adaptive brightness that macOS implements for the built-in display
It works well along Night Shift and True Tone (and f.lux if Gamma/Software controls are not used)

Version: 5.3.0
NOTE: Versions 4.0 onward will NOT work with macOS 10.14. Stick with v3.2.3. There's an error in the coding for v3.2.3 that thinks it can be updated to v4.0.2. Do NOT do it, because the result is that Lunar 4 will ask for Accessibility permission, then permanently CRASH. Stick with v3.2.3. You can download v3.2.3 from the dev's website.

For the first time, I can control the external monitor on my Mac M1 Mini. Awesome, and thanks for the great software!

Version: 4.5.1
Well, I can now control my external monitor (LG 4K HDR) brightness with my Apple keyboard using DDC (USB-C to Display Port cable from M1 Mac mini). Excellent work by all involved!
