Help!, Stuck at 'couldn't alloc class "AppleKeyStoreTest"'

[craighazan]

Just replaced the A320I-K with a Gigabyte A520i-AC, I keep getting stuck here.

Craig, try this revised EFI.

I have added SSDT-CPUR, made a few other changes, cleaned up the config.plist.

Make sure you use the iMacPro1,1 SMBIOS when adding the Serial Number etc to the config.plist. Do not use an iMac SMBIOS with an AMD Hack.

Thanks @Edhawk. Working perfectly on the 520i. Just like to add that the 320 was the less restricted in regards to Ryzen 5000 CPU's. In Cinebench the 5700X was restricted to 3.8GHz, the 320 was 3.9GHz.
