Lunar for Mac4.2.1

19 June 2021

Intelligent adaptive brightness for your external display.

What is Lunar for Mac

Lunar lets you control and sync the brightness of your monitors

  • 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)

What's new in Lunar

Version 4.2.1:
  • Fix flicker because of switching to/from fullscreen apps
  • Fix app not responding on startup because of blocking the main thread too early in the startup process
