Odd response when trying to spoof en0

[JakeSobelman]

Getting a strange response whenever I try to spoof en0, it fails on all interfaces. Recently installed python on my machine again, but this was working just a few days ago.

sudo spoof-mac.py set 00:00:00:00:00 en0

It looks like you're running an old version (2.0.0). Try installing the latest version of SpoofMAC, which is 2.1.1.

sudo pip install SpoofMAC
