spoof-mac installation details
I brewed it on my mac from https://formulae.brew.sh/formula/spoof-mac
This might be duplicate of issue https://github.com/feross/SpoofMAC/issues/104. I realized that the randomizing using spoof-mac still works!
sudo spoof-mac randomize en0
This is odd because your underlying method call is the same. https://github.com/feross/SpoofMAC/blob/master/scripts/spoof-mac.py#L118
in my case, PATH resolved ifconfig to one installed by devbox (i.e., /Users/me/.local/share/devbox/global/default/.devbox/nix/profile/default/bin/ifconfig) instead of the necessary /sbin/ifconfig
removed the linked ifconfig and then which ifconfig returned /sbin/ifconfig and the sudo spoof-mac randomize en0 command worked!
