Hi MaLd0n,
Unfortunately, my system doesn't boot with your clover...
But I have some good news
With your DSDT.aml and some changes I can view all PCI devices in system report and I can get all usb ports to work with minimum problems.
With the AMDRadeonPro.kext finally, I have Hardware decode acceleration for H264&H265
I think the only problem that I have to resolve is my front USB3 ports, recognized as USB2...
Could you please do something for this?
THANKS!
P.S The previous system errors are because I have wrong bios settings after the bios update.
I fix it
I am attaching you the new files and some screenshots.
EDIT: Unfortunately there are other usb3 ports that work like usb2 ports...
