I have had the same problem. The first thing to do is show the brightness slider menu in the settings menu..
please download this archive file: drive.google.com/file/d/1gVP375At3pq-V68VGD3TR0G8VMoCHo4E/view?usp=sharing
this is how I do it :
1. Delete this kext from /System/Library/Extensions/ (if exists)
• delete IntelBacklight.kext
• delete ACPIBacklight.kext
• delete AppleBacklightFixup.kext
nb: you can use rm command to delete the kext.
for example, run this commands from terminal:
sudo rm -rf /System/Library/Extensions/IntelBacklight.kext
sudo rm -rf /System/Library/Extensions/ACPIBacklight.kext
sudo rm -rf /System/Library/Extensions/AppleBacklightFixup.kext
2. Install kext to /System/Library/Extensions/ (if not exists)
• install AppleBacklight.kext
• install AppleBacklightExpert.kext
nb: you can use Kext Wizard or use cp command to install that kext
for example, run this commands from terminal:
sudo cp -R /Users/Jones/Desktop/AppleBacklight.kext /System/Library/Extensions/
sudo cp -R /Users/Jones/Desktop/AppleBacklightExpert.kext /System/Library/Extensions/
3. Reboot
after rebooting, the slider menu will appear in the macOS settings. try the slider, does this work?
if the brightness slider doesn't work, do these steps :
1. download the SSDT-PLNF.aml patch. You can get it in the RehabMan-BacklightFixup-2018-1013.zip or use the kext file from archive that has been downloaded at the google drive link above
2. copy SSDT-PLNF.aml from Rehabman to clover directory /EFI/CLOVER/ACPI/patched/
3. Reboot
nb: you only need SSDT-PLNF.aml file. Kext file AppleBacklightFixup.kext from RehabMan-BacklightFixup-2018-1013.zip is not used. if you use that kext, maybe the brightness slider will disappear again..
