Hello, I've been researching for days about Fn+F11 and Fn+F12 to control screen brightness on Monterey. I tried all my best followed these topics: But can't enable brightness hotkey, current here are all hotkey work native: Fn+Esc (Enable/ Disable Fn key) with On Screen Display OSD Fn+F1, F2, F3 for System Volume level with OSD Fn+F4, F5, F6 for Media control without OSD Fn+PrintScr for disconnect wifi (has no OSD) Firstly follow The Dortania Guide Brightness key work with Fn+S, B. But after tried fix it, it gone too. I tried BrightnessKey.Kext too but still nothing. Here my EFI, DSDT just removed errors, OSCheckFix, kind of keyboard and trackpad with dmesg | grep -i input in Linux and IOReg file with IORegistryExplorer.app v2.1, Could you give some directions on how to solve this, please? Many thank! EFI OC 0.8.3 HackBook Pro.ioreg DSDT.dsl.error.removed.fixOSCheck.zip dmesg_grep_input.rtf.zip
