Hey, first time here on OSXLatitude. I was wondering if I could get some help with my macOS install. I'm already running latest Sierra (10.12.6 at the time of writing). Almost everything works, but I have some issues that I haven't been able to debug. 

 

First: My brightness keys just work as mute unmute when using the AppleSmartTouchpadPS2.kext (I think it was called this way) (I have a ELAN trackpad and I can't live without 2 finger scrolling) . I've been trying to stop the kext from attaching to those keys, unsucessfully. Any help on this would be greatly appreciated.

 

Second: My laptop won't shutdown properly (ie. it powers off okay, but then it stops responding with fans full speed and both power and HDD activity LEDs on.) I have tried a lot of methods in Clover (FixShutdown, HaltEnabler) but they didn't work.

I'll attach EFI/Clover (with original ACPI table dump, modified DSDT, config.plist, etc..) and ACPI table dump under macOS.

Check the BIOS, see if you have 'Wake on LAN" enabled. Disable if you have it.

Check also for WLAN, WWAN, Bluetooth, AC...

 

Try using Karabiner-Element app to re-assign the Fn keys for Brightness, audio...etc

My laptop bios is very limited. I've found that I have Network boot off, but the wake-on-lan thing isn't there. Also, the computer reboots just fine. it's just shutdown. Maybe there's some dsdt edit I might have to do? I'm going to disable the internal bluetooth since it isn't compatible (rtl8723be) just to see if it is the adapter.

I have installed karabiner, but haven't yet used it to reassign keys, as you can see here, Karabiner-Eventviewer says that when I press my brightness up and brightness down keys. Effectively, my brightness keys are working, but since the AppleSmartTouchPadPS2.kext also send a mute keypress when I press my buttons, macOS just ignores my brightness keys.
