I want to go to black apple, 10.13.6. My motherboard is MSI x570. But it got stuck during installation. Is there a god asking for advice? thank you?

List your full specs. Do you actually need support for both Broadcom and Intel Wifi for example?

Can't help without knowing what is actually in your PC.
 
That partly answers my question. Which Wifi do you have?
 
In that case try with this. I've updated your EFI to OC 0.7.7 along with updating of kexts. Updated the kernel patches to the newest version.

Do you have above 4G enabled in the BIOS? If not just add npci=0x2000 to the boot args in your config.
