Tutorial - Spoof MAC Address in OS X

UPDATE!
The spoof command is slightly different if you are using 10.5/Leopard!

This is a quick and easy way to spoof your MAC address in OS X.

use this command to get your current ethernet MAC address:
ifconfig en0 | grep ether

use this command to spoof a new MAC address
10.5/Leopard:
sudo ifconfig en0 lladdr [new mac here]
10.4/Tiger:
sudo ifconfig en0 ether [new mac here]
...without the brackets.

I figured it out. You have to disconnect from the current network, but you should not turn airport off.

I am running os X 10.5.7

Disconnect from any wireless networks by clicking on the join other network in the airport drop down. Type random characters in the network name field. Click connect. Click cancel while it tries to connect to your fake network. Do not turn airport off.

To change to a mac address, enter this command in the terminal, replacing the mac address with one of your choosing

sudo ifconfig en1 ether 00:bb:00:bb:00:bb

This will revert to the original address when you reboot.
