Support for MacOS Catalina

[Jolopu]

After upgrade to Catalina NativeDisplayBrightness stopped working. The process starts but there is no menu and the brightness keys don't react. New installation and updating the security settings brought no change. Will there be Catalina support?

It supports Catalina, though. I’m successfully using the app on two different machines running Catalina – one was upgraded from Mojave and another had a fresh installation.

So there’s probably another reason why it’s not working for you.

@Jolopu You might need to go into System Preferences -> Security & Privacy
And make sure that the app is ticked under "Accessibility"

Thanks Kevin. I did that but no change. Process is running but no GUI. I used this fork:
https://github.com/KAMIKAZEUA/NativeDisplayBrightness/
This worked for me.

I found an even better alternative:
https://github.com/the0neyouseek/MonitorControl
It recognizes my monitor. I can even set the contrast.

@Jolopu Thanks a lot! It works so much better!
I can finally use F1/F2 for their true purpose and use brightness keys for the brightness!

Not working on MacOs 10.15.4 (MBP 15" retina early 2013). I can see the native osd graphics by pressing fn+F1/F2 but nothing happens. Built and reinstalled several times. I also tried MonitorControl and it is not working either. Please let me know if you find out something.

I'm using 10.15.4 without issue. Did it work for you on other macOS versions?
Did you enable MonitorControl in Accessibility and restart the app?
Does your monitor supports DDC/CI?
Are you plugging monitor directly to computer or via some kind of a dock?

Actually I need the application for the built-in retina display. Since I have to force the power-off of the discreteGPU (NVidia GeForce GT650M) the native brightness control does not work. I don’t know if the native retina display supports DDC/CI, but others suggest to use NativeDisplayBrightness to solve this issue in my this scenario. I enabled both MonitorControl and NativeDisplayBrightness in accessibility and also rebooted.
Unfortunately I haven’t tried the apps in previous versions of MacOs.

Built in display brightness should be controlled native both when driven by iGPU/dGPU
