Apple Display Brightness Control – A simple program to control the brightness of Apple displays (Pro Display XDR, Studio Display) on Linux.

Based on acdcontrol by Pavel Gurevich. Modified to support Apple Pro Display XDR and Apple Studio Display. This is needed as Apple in its infinite wisdom decided to use a proprietary USB-based protocol to control brightness instead of the industry-standard DDC.

Note that I no longer use this. I gave my Apple Studio Display to my wife. I'm now using a Dough Spectrum One monitor.
