Changing your MAC Address
Mac App Store only
WiFiSpoof does not have the permissions needed to change your MAC Address.
But don't worry, all you need to do is download the following file, double-click to open and drop the contained "WiFiSpoof MAS Helper" app into your Applications folder.
Theres one more thing to do: double-click the "WiFiSpoof MAS Helper" app once to open and authorize the helper.
Nice and Easy :)
