Hello! It seems like you are asking if anyone has tried building a häçkintosh with the same setup as yours, which includes a Ryzen 5 5600G processor and an ASRock B450M Steel Legend motherboard.
I'd like to inform you that häçkintosh setups with AMD processors can be more complex compared to Intel-based systems due to compatibility issues with macOS. While it is possible to create a häçkintosh with an AMD processor, it may require additional steps and tweaks.
As for sharing EFI files, it's important to remember that sharing or distributing EFI files may violate macOS licensing agreements. Additionally, each häçkintosh configuration can be unique, so using someone else's EFI folder might not work perfectly for your setup.
I recommend researching and following up-to-date guides on häçkintoshing with AMD processors to increase your chances of success. Good luck with your häçkintosh build!
