1. Patched my DSDT
2. Installed IntelBacklight.Kext Using kextWizard
3. Installed Brightness From bergdesign Link
4. Rebooted the system
 
Sorry..
here is the complete file

FYI: Clover does not read ACPI/patched/SSDT-IGPU.dsl
Content in ACPI/patched must be compiled as AML.

You did not implement backlight control correctly. As per post #1, IntelBacklight.kext does not work with 10.12.4 or later.
Read here if you're curious:

There is a LOT of other problems with your setup.

Your laptop has a guide:
https://www.tonymacx86.com/threads/...ebook-probook-others-with-clover-uefi.168236/

The guide implements the method linked above (with AppleBacklightInjector.kext).
 
Hi RehabMan,

I have a working slider in SysPrefs-> Displays:clap:. Brightness key that works is fn + f5 (f17?) for up, down ?:rolleyes:


Would like to map brightness keys a bit different on my MSI Laptop.

See attached picture which shows, among other things, my keyboard and arrow keys:
Brightness.jpg



Has extracted scan codes for fn + arrow keys up and down with your ioio binary;Console shows:

ApplePS2Keyboard: Send key e078 = 80 down (arrow keys up)
ApplePS2Keyboard: Send key e077 = 80 down (arrow keys down)



Have tried editing the values in info.plist below: IOKitPersonalities-> ApplePS2Keyboard-> Platform Profile-> DELL-> SNB-CPT-> Function Keys Special->

Map acpi RKA2 to f4 brightness down
Map acpi RKA1 to f5 brightness up


Of course, that did not work ... Do you have any tips on howto ?


Please help. Thank you!
