Cambio de MAC

[exup]

Sacado del man de ifconfig

ether Another name for the lladdr parameter.

lladdr addr
Set the link-level address on an interface. This can be used to
e.g. set a new MAC address on an ethernet interface, though the
mechanism used is not ethernet-specific. The address addr is
specified as a series of colon-separated hex digits. If the
interface is already up when this option is used, it will be
briefly brought down and then brought back up again in order to
ensure that the receive filter in the underlying ethernet hard-
ware is properly reprogrammed.

asi que me imagino que

Code:

ifconfig en0 ether <direccion MAC>

o tambien

Code:

ifconfig en0 lladdr <direccion MAC>

en0 seria el nombre de la interface ethernet, si tuvieses dos pues en0, en1[…] y asi. Respecto al airport extreme, ni idea aunque quiza por el mismo metodo. Lanza un

Code:

ifconfig -a

antes para averiguar el nombre de la interface.

A todo esto, yo no lo he probado, asi que asegurate antes de que es lo correcto.
