when try to change the mac address of the typc network adapter, the program exit with the following error.

ifconfig: ioctl (SIOCAIFADDR): Operation not supported on socket

I do get exactly the same. Did you get anywhere with this? It works fine on en0 (Wi-Fi) but on on USB-C adapter. Running on MacOS Monterey and Big Sur:
