1) I had to add ApfsDriverLoader.efi driver, without it OC wasn't detecting my MacOS drive. Do you know if I need to keep it or the way how to boot without it?

You must have been on a very old version of macOS...

Go to config.plist > UEFI > APFS and set:

MinDate = "-1" (without the quotes)
MinVersion = "-1" (without the quotes)

I'm running Catalina 10.15.7

Try changing MinDate and MinVersion to -1 and see if it works without ApfsDriverLoader.

Use the latest EFI from post #1. Don't change anything except add Serial, Board Serial, and UUID to config.plist. Clear NVRAM at OpenCore boot picker on first boot.

Thank you

Alright, that helped! thank you!
Before OC boots I'm getting "ocs no schema for legacyenable at 2 index, context (NVRAM)!", do I need to do anything about it?

Open your config.plist with either a plist editor or TextEdit. Search for the line that contains "LegacyEnable" and delete the entire line.

I was able to boot with 6800xt installed, I had to enable CSM for that, without it computer wasn't booting.
I wonder if there is a way to display GPU temperature\frequency in macOS, I remember I've used fakeSMC for my Vega56, do you know any other way?

Also, I remember that with Clover I had to change from 18.3 to 18.1 when I've removed my dGPU, do I need to do the same with OpenCore? macOS identified it as iMac (21.5-inch, 2017) now, I wonder if I need to change that? The reason why I ask is that with 18,1 macOS identifies my CPU correctly as 6-core i7, but with 18,3 it appears as 6-core i5. Do I need to be concerned about that? In Catalina it was i7 in both SMBIOS versions.

And the last question, it takes forever too boot macOS, a minute or so, during this wait time I see that the hard drive is used a lot, so I am guessing that it is actually doing something, however my Clover Catalina was booting within 15 seconds or so. (Disregard this, I found the reason, and that there is no solution)

As usual, a huge thanks for your help. This hack brings me a lot of joy, and that is all possible because of your help Chef!

Try adding the following kext for Radeon sensors.

Thanks!
I found an interesting thing, when I tried to use 18,1 iMacPro1,1, 19,1 with either automatically selected ProcessorType (which incorrectly identifies 8700K) in config or with value 0 (which correctly identifies 8700K) and 18,3 with value 0 my R23 cinebench score was 7700-8300 depending on the SMBIOS. But when I used 18,3 with automatic ProcessorType selection my score is 8800-8900, which is normal for stock 8700K.

I don't know. I have never messed with processor type. My CPUs have always been properly detected.
