The efi file you uploaded was fine until mac os installation. I can't connect to the internet with the built-in Ethernet card (not wifi) . How can I do it? I am using ryzen 5600x & rx5600xt, B550 Aorus Pro ac. Of course, in windows10, the Internet works well with the built-in Ethernet (LAN).
@yourbeat :
First of all, I would like to ask you to enter the hardware you use in your profile.
If you are using the same board which bios version?
As you can see on the snapshot, the network settings need to be adjusted. Then it should work without problems even after a reboot.
