NOTE: Looks like Apple killed tis in Sonoma. There may be no viable workaround. If I find one, I will update this script. This allows you to create and assign any MAC address you like for macOS Wi-Fi or Ethernet connections. If you don’t supply one a random mac will be created for you.

Looks like Apple killed this in Sonoma. There may be no practical workaround. If I find one, I'll update.
