Original Question:
Hi.
I'm trying to install Big Sur on my PC (see account hardware). I use OpenCore 0.7.6 and the Dortania guide for desktop Comet Lake config.
I select Install macOS Big Sur (external) in OC menu. When the Apple logo is going to appear the screen gets black (no video signal).
What I tried:
1) AAPL,ig-platform-id 07009B3E and 00009B3E
2) BigSur and Catalina
3) iMac20,1 and iMac19,1
Attachments:
- EFI folder (removed)
- last loading screen
Please, help. Thanks.
