@shuhung Did you get DRM working?

Please disable IGPU in BIOS and try this EFI.

Also, remember to refresh VideoProc by pressing the two arrow semi-circles.

Edit:
Forgot to change system definition to iMacPro1,1. Fixed now.

Dude.. it worked! <3
I checked config.plist and kexts you provided but i couldn't find what did the trick!
Can you explain what made it possible?

Thank you so much!

(OT: Why does a Facetime error pop up now at start? ahaha)

I made quite a few changes. Can't remember all of them... Most important was that I got rid of your ig-platform-id, device-id injections and graphics injections.

I have no idea why you get FaceTime error.

I see, thanks a lot for the time you took to fix my EFI folder

@pastrychef, is DRM working on your system with the Vega card?

Yes.

 

[CyCLoBoT]

Yes.

If Netflix is working in Chrome, does it mean that DRM is working? In Safari, the entire system hangs when I access Netflix.

If it doesn't work in Safari, DRM isn't working.

I guess I'll have to upgrade my card then.

Try using a system definition that doesn't use IGPU.
