Issues
In order for 5GHz wifi band to work, AirportBrcmFixup.kext must be used. In order for Reboot/Shutdown to work, HS10 USB port must be excluded from the USB map. It maps to internal LED Controller and prevents proper system Reboot/Shutdown.
DRM
Apple TV+ works with boot arguments shikigva=80 and unfairgva=1. Netflix in Safari is working.
