<< Solved >> OpenCore 0.6.1_Catalina 10.15.7_Asus z370-a_i7 8700K : Boot issue

[asheenlevrai]

Hi

I'm trying to install Catalina 10.15.7 using OpenCore 0.6.1 on the following hardware:
- Asus z370-a (latest BIOS)
- Intel i7 8700k
- Rx590 8GB
- 2x 8GB 2400MHz DDR4
- 240GB Corsair MP500 PCIe3.0 x4 NVME SSD

This machine is currently running Mojave 10.14.6 via Clover 4910 but I want to perform a clean install (wipe the current SSD).

I followed the guide on Dortania to create the USB installer including all kexts, config.plist, etc

(config.plist attached below)

However, upon booting on the USB installer and selecting
"macOS base system (external)"
I get a (kernel?) panic (see screenshot)

I don't know how to troubleshoot this.
Could you please help?

NOTES:
The following settings are apparently absent from the BIOS and thus I couldn't change them or check whether they are set to what they should:
- Parallel port (-> disabled) : there is no parallel port on this MB
- Intel platform trust (-> disabled)
- Execute disabled bit (-> enabled)
- EHCI/XHCI hand-off (-> enabled) : I believe there are only XHCI controllers on this MB

Thank you very much in advance for your help

Best,
-a-

What would make it look like an AMD system to this sanity checker?

Failure to select the correct system ? (Default is AMD)

Yeah, my bad. It took a minute for me to realize what an idiot I was ;p

Again, my config.plist seems OK. At least to this tool...

I didn't use SSDT-AWAC.aml as it is apparently not necessary for ASUS z370 boards but on the guide they mention SSDT-RTC0 as an alternative.
I couldn't find SSDT-RTC0.aml.
Maybe that is the source of my problem?
Maybe not...
(I tried adding SSDT-AWAC.aml to my config.plist and in EFI/OC/ACPI but there was no effect)
(I also tried SSDT-PMC.aml from here -> same thing)

Found the culprit!
I needed to enable EnableWriteUnprotector, although the guide recommends not to.
The setting of RebuildAppleMemoryMap (possibly conflicting) doesn't seem to have any effect.
