Ethernet (IntelMausi)

Hope you are using the Lates Release of IntelMausi. Have you added the required device property or bootargs?

For ethernet you would need IntelMausi kext as it is an intel chip. https://github.com/acidanthera/IntelMausi

Your board appears to have the Intel I219-V Ethernet chipset, so it should work with IntelMuasiEthernet... unless your copy of the kext is just too old? It's had a name change within the past 8 years, after all. You can find the latest version here: https://github.com/acidanthera/IntelMausi/releases

The OpenCore Install Guide points to IntelMausi (which is the one I would need), which I understand is acidantheras own fork of IntelMausiEthernet. However, In the Kext Repo which is linked from the very same page, there's only the IntelMausiEthernet-version.
