Extend Wifi usage indefinitely on your macbook

mac_spoofer

#
# Rock on free cafe or library wifi that impose horrendous limit on your usage.
# It spoofs your device's MAC address, run it once to turn on, twice to turn off. You get a random MAC addr everytime. 
# So to extend on an existing spoofing session, turn off, then turn on again.
