Hey guys,

For 4 days long i'm trying to install macos big sur on my computer, but everytime with every EFI's and every config.plist I have the same result: black screen after this message.


My plan is deactivate the gpu and use uhd630 with the hdmi cable on motherboard, I read a lot of people who have success on this way. I'm asking for your help, because I don't know what to do anymore


there is the error and the last EFI I have tried

sry for bad english and thank you so much
