MSI B550 motherboard, any news?

[chrollo616]

Hy guys!

Specs:
MSI B550-A PRO (BIOS version: 7C56vA6 2021-05-17)
AMD Ryzen 7 5800X
AMD Radeon RX 580

I have a working installation of 11.4 BigSur and I've spent a lot of time trying to update to 12.2.1 Monterey before finding out that there's a problem with MSI B550 boards...

Have any of you been able to install any version of Monterey to an MSI B550 board?
Is there any news regarding this issue?

Thanks.

I up this post as I am on the same situation...
The only way at the moment is to downgrade the bios version to one of the oldest ... tried once but I got my WIN11 system corrupted right after the downgrade.

I don't know of anyone working on that. It was looked into for some time by the devs but no solution was found.

Have you guys tried adding MCEAppleReporterDisabler.kext to your builds? That should (normally) get you past the Monterey boot on Ryzen setups.
If not then enabling AppleXcpmCfgLock and AppleXcpmExtraMsrs also may help in some circumstances.
Also try enabling AdviseWindows and/or ProvideCurrentCPUInfo. And adding 3842 to the ProcessorType.
And if that still fails, try adding cpus=1 as a boot-arg.

I tried that CPUs = 1 doesn't work

Did you try adding AppleMCEReporterDisabler?
