The first thing I always recomend with a stackshot error of any kind is to disable the IGPU... It is possible it is configured correctly for Catalina but not for Big Sur. I learned this first hand when migrating my laptop over to Big Sur. I never experienced any stackshot errors with my desktop I am guessing because I do not have IGPU enabled. Big Sur is a bit more finicky so a setting that might be wrong in Catalina might need to be correct in Big Sur other wise you will get an error.

I did disable on bios the internal graphic and using a DVI port on the graphic card to my monitor.

Catalina is not configured to use clover, clover is configured to boot MacOS. Your clover config could likely boot Mojave, High Sierra, Sierra. If you lost the Serial log into iCloud and look at the Macs that are linked to your Apple ID.

Yes you can run two different versions of Mac OS on two different SSD drives. Tonight for the sake of checking some stuff DRM stuff I booted a Catalina drive with a Mac Pro 5,1 & 6,1 and iMac 18,1 system definitions logged into my account on all three of the different system definitions and checked DRM stuff.

If I were you I would forget about the old serial refresh the System definition get a new board number, serial and the likes save the config and reboot. You're likely getting an error because you do not have a serial!

I started the process again!.
Making the bootable file
sudo "/Applications/Install macOS Big Sur.app/Contents/Resources/createinstallmedia" --volume /Volumes/Bs-installer
would mount the EFI and would copy the files that has been shared and would then boot to see how it goes...
hectic process but something to learn with all new install on Hackintosh!>.

The only thing you need for a RX580 GPU is Whatevergreen and Lilu.

I really had a hard time since I was not good with OC... finally made it work !!!
I did connect my iPad via the USB cable and voila Sidecar works perfectly ! It never worked on Catalina.
All Applications works smoothly!

Please can you post your EFI.. I think we have similar builds and I had no luck at all with OpenCore over 3 days
