Brightness level settings not found in macOS settings
my laptop screen is too bright. I want to reduce the brightness on the screen but I did not find the slider menu to adjust the brightness. I have tried using the Brightness Fix patch to DSDT but it still doesn't work.
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..
