Is there any confirmed success that these kexts work in Big Sur? I've tried Clover injection and install to L/E. Thank you in advance for any help you can provide.
Disregard: After some tinkering I found out my issue is not with these drivers, but instead the fact that I can't edit the AppleBCM5701Ethernet plugin inside IONetworkingFamily.kext in S/L/E in Big Sur unlike previous macOS versions.
