I'm sorry, I don't know much about OpenCORE. I don't have much time to learn now. Maybe some computers don't support it. But I can't determine the source of the problem and how to deal with it |
how did you installed big sur ??? can you please provide your EFI folder......thanks. |

Can you please share efi folder of working big sur???

Graphics are not working
I somehow manage to install big sur but graphics doesn’t work. If i use your platform id under device properties black screen issue; just went black after booting the same thing appeared on catalina before. If connect laptop with hdmi screen works as external but on laptop it’s black.
I also tried my catalina devices properties but it doesn’t boot at all. Stuck there.
