Changing the MAC Address on Mac OS X

All we need is to type this in Terminal

sudo ifconfig en0 lladdr 00:00:00:00:00:01

or

sudo ifconfig en0 ether 00:00:00:00:00:01

Just change 00:00:00:00:00:01 with the MAC address we need.

It seems that for older versions of Mac OS X (prior to Tiger – OS X 10.4) we will need this patch:  http://slagheap.net/etherspoof/ .
