Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

......
You can literally just change the system name from iMac19,1 to iMac20,2 and back again, without changing anything else. But once you commit to a system name, you should not change it.

Why is that?

On a side note - I am about to try to do a hack with a 10900k; from what I read, there should be no difference between iMac19,1 and iMac20,2, no?

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.

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

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.

Job done! Welcome to the Society of Mad Scientists.

Haha, thanks, but do I still need to generate SSDT-DTGP.aml and SSDT-TB3HP.aml files? Do I flash my chip with those files?

Job done means exactly that.
