Dear all,

 

I'am using macOS Mojave 10.14.5 and I setup as this topic: 

 

 

After I install, I can use F1 for mute, F2 for volume_decrement, F3 for volume_decrement and F6 for brightness_decrement, but I cant control brightness_increment.

And I want "F" function as Windows (F11&F12) for brightness control.

 

Plz help me. Thank so much.

In relation to this topic. I have a Dell E7470, I5 6300U. I have used Jake's pack to install Catalina and both fn + B - Fn + s, and f11 - f12 (with Karabiner elements) show the brightness bar, but it does not decrease the level, until it reaches the end of the bar that the brightness is gone suddenly. Any idea?...
