Boot issue on OpenCore 0.6.1, Catalina 10.15.7, Asus z370-a, i7 8700K

Hi

After successfully using OpenCore 0.6.1 to install Catalina on my Ryzentoshes, I'm trying to install Catalina 10.15.7 on one of my Intel builds:

- 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 a new USB installer for Coffee Lake, including all kexts, config.plist (attached below), etc
Let me know if I forgot something here:

However, upon booting on the USB installer and selecting

"macOS base system (external)"

I get a (kernel?) panic (see screenshot)

Any idea what may cause this? My Google-fu didn't lead me anywhere useful...

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...

NOTES:

The guide on Dortania recommends changing the following BIOS settings. However, they are apparently absent from the BIOS on the z370-a 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,

Hi,

your config looks flawless, except for no generated SMBIOS under Generic. I found a SSDT-RTC0. You can try with this one.

Thank you Where did you find this file?

I tried it but it's still the same thing...

Do you think the AWAC/RPC clock, or whatever that is, is the cause of the problem?

I was wondering if the CPU might no be recognized or something like that. Again, I have no idea what all this gibberish means during the boot sequence... Or maybe a CFG-lock issue? Although I disabled it in the BIOS... but I think I have redundant settings in config.plist to disable CFG-lock. Maybe that is wrong...

Two things:

1. WhateverGreen.kext should be the third one in config, not at last

2. BIOS settings: CSM is disabled?

1) I used properTree -> OC clean snapshot. This is supposed to arrange them automatically in the good order, right?

In addition, https://opencore.slowgeek.com seems to indicate my config.plist looks fine. I will try moving WEG to 3rd position and give it a shot, though. Thanks

2) yes

hello asheenlevrai

please put your hardware - software specs into your profile or your signature, so it would be easier for the supporters here to support you for now and later ,

thx

how-to:

• profile: upper right -> controlcenter -> edit profile
• signature: upper right -> controlcenter -> user account -> signature

I'll do that. My only problem is that I have about 15 rigs I manage on a daily basis... Which one should I consider "my hardware"?

kuko Actually I don't know hot to move WEG in third position using ProperTree...

hackmac004 I tried your EFI and I can reach the installer

I looked at how your config.plist is different from mine and actually there are MANY differences:

- You have both SSDT-AWAC and SSDT-PMC while I have none. I believe I tried adding both too and it didn't work but I should double-check that

- You have a whole bunch of tools that I don't have.

- You have nothing in DeviceProperties

- Your use iMacPro1,1 while I use iMac19,1

Otherwise I found at least 18 differences, most of which I have no idea what it implies. I will have to look into all that carefully I guess.

Thanks a LOT!

EDIT: I tried reverting all the settings from your config.plist to what they are in mine, except for anything related to ACPI and Tools, and I get the same kernel panic at boot. Thus I believe it indicates that the content of ACPI and Tools folders are not where I should be looking for the cause of my issue but rather in the settings of my config.plist. I have a hunch that it has to do with the SystemProductName, but I will look into all the settings to see what they mean...

EDIT2:

I think I nailed it...

I needed to enable EnableWriteUnprotector, although the guide recommends not to.

The setting of RebuildAppleMemoryMap (possibly conflicting) doesn't seem to have any effect.
