In theory iMac20,2 is for Comet Lake processors (10th gen) and iMac19,1 is for Coffee Lake Refresh (9th gen). But in practice we don't notice any difference. Nevertheless, theoretically iMac20,2 is better if you have a 10th gen CPU.

That was my guess, so I will go with iMac20,2. I have a Vision G but it has GC-Titan Ridge 2.0 card installed, so I won't do this step, right?
Disable and/or remove SSDT-TB3HP.aml and SSDT-DTPG.aml from the ACPI section because the Vision G does not have an on-board Thunderbolt controller

When you change platforms, Apple's servers will note the change, and possibly sign you out of iMessage, iCloud, the App Store, etc., and sometimes it can be a pain to reenable those services on the new platform. But if you're not signed into any of Apple's services then changing your platform shouldn't matter at all.

I see. I was wondering if it had anything to do with it. Thanks

Fortunately we provide a Thunderbolt SSDT that is fully set up for both original and flashed Thunderbolt firmware, so nothing else is needed.

When you say there are 3 original firmware files in the chip, loud sirens and red flashes go off!!
  • Are you sure you're looking at the right chip?
  • If you've extracted the original firmware, please compress and post it so we can verify it's the right chip.
These are the 3 original files that I was talking about, I think I might have confused you. I have already flash the chip with your "Gigabyte-Vision-D-NVM-50-Elias64Fr-CaseySJ.bin" firmware, what should I do next, or maybe that is fine?

SSDT-TB3HP.aml will have to be adjusted slightly for the "root port" of the GC-Titan Ridge. After installing the GC-Titan Ridge, simply run IORegistryExplorer --> File --> Save As..., and post the saved file. We can modify the SSDT's root port for you.

Hello @nss,
  • Do you have multiple operating systems installed such as Windows and/or Linux?
  • When you get this error, just go to BIOS Setup --> Boot and set first boot priority to the name of your macOS SSD.
Hi,
Thanks for your response, I've tried what you suggested, but the BIOS settings revert themselves every time I try this.
This is what I did:
Error pops on my screen as I try to boot macOS with "no entrance" sign,
restarted PC by clicking the physical PC restart button because I can't enter BIOS from OpenCore boot menu
entered BIOS settings,
entered Boot tab,
Boot order was:
1. OpenCore
2. name of macOS NVMe,
3. Windows Boot Manager.

Switched it to:
1. name of macOS NVMe,
2. OpenCore
3. Windows Boot Manager.

Also updated the time because it wasn't accurate, then Save & Exit, BOOT settings reverted and macOS somehow boots, until the error will happen once again.

Is there any solution to prevent BIOS settings from reverting themselves?

I wonder if the coin cell battery on the motherboard is depleted...

You think I should replace the motherboard's battery?
