Have you tried using my Base EFI?

Also flash a later BIOS like 3301

updated BIOS from 1602 to 3201. (1602 worked great for clover for many years, so i never needed to changed it).
tried your Base-EFI (MacPro7,1), and created new Serial Number and SMUUID.

got a little further, but gets stuck (freezes)

Did you follow the recommended BIOS settings? and you may need to try BIOS 3301. Not sure if the MSR lock is still broken in 3201

Yes, on opencore config.plist, and i suggest you to read the dortania guide and take the time you need to understand how it works, otherwise you'll end up constantly depending on others to solve your issues. Hope you'll follow my hint.

You'll be able to set language later and pay attention to the nvram part of the config file.

It should already be in english if you used my EFI but glad you got it to work
Did you just updated to a W5500 mate? Like I see in you sign.

How doy you judge it? It was a choice between RX 5700 XT and that W5500 for me and I ended up with the 5700XT.

Guess I updated a little early since it's still on it's way but I should get it Friday. I'll update how it works out. I wanted a single slot card without watercooling and since I don't do anything super GPU intensive in mac I felt the W5500 was pretty good choice. Just really hope it works :lol:
