Asrock Fatal1ty B450 Gaming ITX/ac Ryzen5 3600x RX570 Monterey 12.4

I have been using Big Sur with this system since my first attempt with Mojave as I mentioned here before: https://forum.amd-osx.com/index.php...-itx-ac-oc-0-5-7-mojave-10-14-6.43/#post-6579

I've decided to update both MacOS and Opencore. I downloaded the new pkg. Followed the guide and gathered all the kexts I have been using with Big Sur. But computer keeps restarting while boot so I added MCE Reporter disabler kext. I also used the old ACPI folder. So, here we are.

Thanks, for some reason this EFI wouldn't even start on my B450 Gaming ITX/ac, wouldn't even load from the boot device UEFI selector.

Which CPU do you have installed? If yours is different from the OP's build you have to adjust for the CPU core count under Kernel > Patches.

It was me being stupid was trying to boot from the wrong volume.
