Trying out with Big Sur beta 5.
Starting with the OC 0.6.0 EFI that's already working for latest Catalina:

• added experimental paches
• disabled some kexts (SMC AMD Ryzen, USB kext too)
• added lilubetall and wegbeta boot args

But it stalls at some point, showing this latest on screen.



then after about 4-5mins, it shows this:



Not sure what this could be. EFI I'm trying with is here.

No issue, after about 15-20mins installer just appears. Bleh.
