Just wanted to add to this chaos. I can also confirm mac address changing of ethernet adapters does not work on OSX Ventura as newts pointed out. I even ordered the Apple Thunderbolt 3 USB-C to Ethernet adapter thinking it would work but it does not. The newer M1 Macbooks do not have the older thunderbolt ports. Does anybody have a list of USB-C to Ethernet adapters that is known to work like newts mentioned?
