Hello again. I've had no luck getting my Ethernet working... After finally having a bit of time to delve into it, I tried to get it going, to no avail. I even reverted to OpenCore 0.8.0 (from the 0.8.1 EFI that
@StefanAM made me) and in the process I think I found out that the new config.plist entry named ForceAquantiaEthernet is what's making the system unstable (i.e. random "your computer restarted because of a problem" when value set to True). So, I think I'll have to settle for the Wi-Fi solution for my internet needs when in Mac on my system (it's still the BCM94360NG m.2 I hope, that's what I'm ordering right now).
@StefanAM When that arrives, can I ask for advice about how to get it working?
