Not working:

1. USB-C port cannot be function completely (can charge iPhone), cannot output for external monitor (maybe the problems of my type-c cable or keyboard mapping?)
2. Fn key not function well. Only function for volume controls with correct keys, brightness function key set in macos keyboard setting.
3. Screen mirroring to external monitor by HDMI is not work because Fn key to screen mirror cannot be set.

The photo below is the USB mapping by hackintool. I have already selected the highlighted items and exported the USBPorts.kext to opencore kexts folder. I cannot found the USB-C port when I connect USB-C device to my laptop. :( Any ideas pls???
