Macshift

  Macshift v1.1, MAC Changing Utility by Nathan True, macshift@natetrue.com
 
  Usage: macshift [options] [mac-address]
 
  Options:
  -i [adapter-name]     The adapter name from Network Connections.
  -r                    Uses a random MAC address. This is the default.
  -d                    Restores the original MAC address.
  --help                Shows this screen.

Macshift uses special undocumented functions in the Windows COM Interface that
allow you to change an adapter's MAC address without needing to restart.
When you change a MAC address, all your connections are closed automatically
and your adapter is reset.

Example usage:

macshift -i “Wireless Network Connection” 002334564775

This would change your wireless MAC to the one above. Your adapter will be disconnected and reset immediately.

macshift -i “Wireless Network Connection” -d

This would restore your MAC address.
