Mac ::: MAC-Address spoofing on Mac OS X

February 1st, 2008 at 23:02

If you ever need another mac address do the following in Terminal.app, which is located in /Applications/Utilities :

10.5 / Leopard:

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

10.4 / Tiger:

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

Edit:

A static method can be found here (thanks to MMM)

Just a precision : this will work for mac wireless address but not for mac wired adress on Leopard!

hi shams,

thanks for the response.
Actually i have just tried that again with both ethernet interfaces on my mac pro.
I am curious:
what happends while you were trying that ?

I was able to change both devices to a new value and re-changing them back to the old values.

Greetings
fidel

Me too, was unable to change MAC address of wired iface (MacOs X 10.5.2)
ifconfig command execs successfuly, although mac is not changed.
Lots of ppl have this problem, it seems there’s no workaround
at this moment.
