BigSur hangs at boot - Opencore // Z390 Gaming X - RX570

My BigSur is installed Opencore, drivers e kexts, DSDT all updated and the boot hangs about 80% at the point shown in the pictures.

I have to hard reset the computer a few times until it passes this point and after that the system runs smothly.

The same computer ran Catalina without this issue.

The System is a Gigabyte Z390 Gaming X, I5 9400f, RX580.


Any hints?

Which method are you using to install BS?

I booted and installed it from the image downloaded from Olarila website with the Z390 EFI folder replaced.

use this folder


disable csm if need


Thanks MaLd0n.

I noticed it is a CLOVER bootloader instead of Opencore. Is there a reason to move to Clover in this case?

And CSM is already disabled.

Thank you.

I have installed this (OC). It is better but still hangs a bit after. With the CLOVER one I have to try more but it didn't hang yet.
