DISCLAIMER - Pay attention!

(Familiarity with ACPI is required)

Patching a DSDT is risky.

Do only if you know risks and how to recover it if something goes wrong!

 

Hi everyone, with the release of new bios for am5 platforms which allow pre-support for 8000 series CPUs we came across a bug that no longer started macos.

@fabiosun and I started by trying these new bios without success in starting macos, until I had the idea of injecting the old dsdt of the previous bios with true on the RebaseRegions quirks.

Subsequently I dedicated myself to patching new bios and removing new conditions that were added :

removing the entire CPVS section generates 30 errors in my case :

I started to correct these errors by removing conditions for loading devices or _PRW methods :

there are so many that it removes the if... string with the bracket { and at the end of the scope also remove a bracket } so as not to generate other errors.

and I also removed this whole part:

have you already tried it?

I've downloaded it for safekeeping. When the new Ryzen 8000 processors hit the market early next year, I will very likely purchase one. 

 

Updating BIOS on my motherboard has been a relatively painful experience, so I do this only when necessary.

I tested with the new DSDT for the X670E Hero, and it worked with BIOS 1709.

Now I'm testing with the previous BIOS and without DSDT to see if it works too.

I had the misfortune of setting up the setup, updating the BIOS and getting this problem with the 1709. LOL!

Thank you very much for all of your help.

I got a panic crash when Ventura tried to go sleep, perhaps I need to add something for the GPU? (6600XT)

I sill have to complete the EFI, I just have the HDMI as output devices, and I'm having some issues renaming the cpuid.

Also I need to map the ports, I'm guessing if I can use the @CaseySJ kexts just to be sure...

Thanks, I'm going to try the USB mapping, but I'm not quite sure how to make it works.

I have just enabled the thunderbolt / USB4 in BIOS, I'm not using those ports atm, but seems that I need to enable them before mapping the ports, If I need to use them in the future.

The thing is I haven't any USB type C device to map those ports, and I'm not sure If I need and how to map those bi-directional ports.

Reading others guides just raise my doubt on how to proceed, dortania guide says we need to plug only USB 3.0 in windows for the mapping, others says we still need to use USB 2.0 and 3.0.

config 6.plist.zip 6.63 kB · 1 download

for problem with cpu name try this config

reset Nvram before starting OSX
for USB mapping problem post an IOREG

Method you say to map USB are the common ones used by AMD comunity

 

Expand  

Hey it worked! Now it shows CPU name :)

 

For the IOREG I just opened the app and saved the file attached, hope it's ok,

I see an error inside perhaps cause I have bluetooth & wifi disabled in BIOS? (I don't need it)

I removed my actual USB port map kexts before booting the EFI (Won't boot with)
