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.

When I used the ifconfig to change the MAC address, it got the error
message.

------------------------------
It's not woking on MACOS sonoma 14.4.1 (23E224), MacBook Air, Apple M1. It
showed the error message: "ifconfig: ioctl (SIOCAIFADDR): Can't assign
requested address"
What is the interface of your Wi-Fi adapter?
