Not working on macOS Monterey

[dynjo]

Any attempt to set a MAC address results in:

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

Same issue here. Changing MAC address with ifconfig isn't working either

[emendelski]

@feross any news about it? Do you know how to overcome this?

Issue resolved in latest update MacOS Version 12.1

Also worked for me on MacOS Version 12.1, using a 16in Macbook Pro M1 Max.

FYI this still works on macOS Ventura 13.3.1. 😄
