Opencore 0.6.2 success with Big Sur but it always boots with black screen

[brendan_siow]

Hi all, my Opencore 0.6.2 Big Sur beta 10 boots all the time but its always starts with black screen.

I know it because when I press the keyboard, there are sound made for typing (even VoiceOver works CMD+F5, see video below)

When I start frustrating and spam typing, the screen glitches and woolaa the screen shows up. But sometimes it can be really hard to "trigger the glitches" and will continue to stuck at black screen or blank screen after boot. (It happens on every boot TT)

Unfortunately no, I've seen when I change the SMBIOS, for the first time I can boot, you need to change SMBIOS every boot

@walaoehh I saw your messages.

Have you reinstalled with beta 11.0.1? That's the one that worked for me, I could not get beta 10 to install at all.

If you like you can post your config.plist here and I'll compare it to mine. EDIT: nvm I saw your link, gonna take a look!

EDIT: I made some changes; please download this version of your EFI folder and retry, but get the latest BS beta first, 11.0.1!
I added my EC fix to ACPI/, also added the MCEDisabler kext to KEXTS/ and checked your config file. Made some corrections based on my own config. Also, I updated your Lilu, WhateverGreen and VirtualSMC kexts; they were older than mine.

I got it by manually searching for updates from the System Preferences. It first offered me 11.0, then cancelled the download after 90%, then offered 11.0.1 and downloaded that.

If you still have the issue then I suppose it must be a BIOS problem. I have an X570 board, unlike you. So maybe your BIOS is different from mine and that produces the problem?

I suspect BIOS issue too.. but I saw another guy with the same motherboard success... maybe I should try to update my BIOS. Thankss
