​

I used the Dortania opencore guide.

​

working and not working :-

everything works except

1.hardware drm for appletv playback

1. iservices(not tested as I do not use them).

3.Sleep and Audio on using Hdmi out.

Using display port sleep works fine. HDMI video is working but hdmi audio level cannot be changed.Also after sleep it always uses display port. (I am still working on these). (Also I am using display port and hdmi adapters to connect my old vga monitor) 

Specific things I had to do :

Apps using graphics accelaration crashed a lot until I updated to Big sur.

Applealc audio was not working with the ssdt I compiled, I had to use the default ones from dortania guide to get it to work.

I used the ssdt spoof method to disable nvida gpu in macos.

DisableRtcChecksum was used to stop Bios error on boot.

Also changed windows to use Utc time. Otherwise windows would show wrong time after rebooting from a macos session. more on this----> https://www.tonymacx86.com/threads/fix-incorrect-time-in-windows-osx-dual-boot.133719/
