    Although spoof-mac can run without root, you must be root to change the MAC.

    The launchdaemon is set to randomize en0.
    You can find the interfaces available by running:
        "spoof-mac list"

    If you wish to change interface randomized at startup change the plist line:
        <string>en0</string>
    to e.g.:
        <string>en1</string>
    EOS
