ASUS X99 Boards - Big Sur (Not Compatible)

[byzyn4ik]

in my opinion this problems realted to incorrect ssdt so try remove ssdt and add nullcpu. And maybe this is problem with VirtualSmc because my friend use fakesmc to boot ( virtualsmc is nit working for him)

I asked my friend for sending me efi folder. He applied this patch and got boot installer. He is using RX580. The config looks ok so interesting why are you getting black screen

Hi, do you have some news from your friend?

Send me a snapshot of verbose with this crash. I've not ever gotten response from him. I checked your config it's looking good.
SandyBridge-e should have cpu patch as correctly I remember to boot >=10.14, so maybe it's related to xeon v1. Using xeon v2 is better for MacOS. I've replaced my 2680v1 to 2667v2 to avoid many issues and patches 2 year ago.
NullCpu should help here if it related to v1.

In the previous config, I had a mistake with adding the patch, I added it like "dictionary", but it should be "Array". I fix it, but no diff.

What I did:
- load from USB in UEFI
- reset NVRAM
- PC was rebooted
- load from USB in UEFI
- click on "install Big Sur Beta"
- running text on the screen an error:

Why not to use OpenCore configurator if you have low skills on manual editing plist. The config was wrong!

Which tool do you use for editing the config.plist?
