Lunar
The defacto app for controlling monitors
Adjust brightness, change volume, switch inputs
#### macOS app for controlling monitors, [with native support for both Intel and Apple Silicon](https://lunar.fyi/#m1)

## DDC/CI
Lunar changes the hardware brightness of the monitor using the DDC protocol.
It doesn't use a software overlay if the monitor supports DDC/CI.
## Installation methods
- Download [Lunar.dmg](https://lunar.fyi/download/latest) from [lunar.fyi](https://lunar.fyi/)
- Or `brew install --cask lunar`
## Features
- **[Native keyboard control](https://lunar.fyi/#keys)** and hotkeys for setting brightness, volume and contrast that respect the min/max values per monitor
- **[1000-to-1600 nits of brightness](https://lunar.fyi/#xdr)** for supported **XDR** and **HDR** displays
- **[Dim brightness below 0%](https://lunar.fyi/#subzero)** for late-night work
- **[Sensor-based Adaptive Brightness](https://lunar.fyi/#sensor)** (and contrast) based on [an external light sensor](https://lunar.fyi/sensor)
- **[Sync-based Adaptive Brightness](https://lunar.fyi/#sync)** (and contrast) based on **the built-in light sensor of the MacBook or iMac**
- **[Location-based Adaptive Brightness](https://lunar.fyi/#location)** (and contrast) based on the sunrise/sunset times in your location
- **[App Presets](https://lunar.fyi/#configuration-page)** if you need more/less brightness for specific activities (watching movies, design work)
- **[Input switching](#input-hotkeys)** from a convenient dropdown or using up to 3 input-specific hotkeys
- **[Screen orientation](https://lunar.fyi/#display-settings-page)** change from the menu bar or using hotkeys (Ctrl+0/9/8/7 mapped to 0°/90°/180°/270° for the display with the cursor on it)
- **[Hidden resolutions](https://lunar.fyi/#display-settings-page)** accessible from a dropdown in the [Display Settings menu](#display-settings)
- **[BlackOut](https://lunar.fyi/#blackout)**: turn off monitors (or the built-in display) selectively while also keeping important functions:
- USB-C charging still works
- Monitor audio keeps playing
- Monitor USB hub remains available
- The built-in keyboard and trackpad are still available for use
- Avoid overheating the MacBook because of using it with the lid closed
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 dimming is not used).

### Contributing
I'm pausing contributions for the moment as Lunar has paid features and isn't compilable because of missing parts of the source code *(Pro features code is encrypted)*.
### Building
Lunar can't be built from this repo as the source code for the paid features is hidden.
