Change mac address in MacOS?

Here here little details. While I'm on the Mac never sat googled nothing better to do) About some patch even says Priscilla.

> ifconfig eth0 hw ether AA:AA:AA:AA:AA:AA does not help...
\r
In Linux the Mac address needs to be changed to the lowered interface. Maybe here the same?
\r
sudo ifconfig en0 down
en0 sudo ifconfig hw ether AA:AA:AA:AA:AA:AA
sudo ifconfig en0 up
\r
Or even one line:
sudo ifconfig en0 down hw ether AA:AA:AA:AA:AA:AA up

forgot sudo?

in mac or is it mac os?
(I'm confused about eth0, mac os native en)

iscsi@pipboy ~ % ifconfig en0
en0: flags=8863 mtu 1500
ether 00:23:32:97:7c:64
media: autoselect
status: inactive
iscsi@pipboy ~ % sudo ifconfig en0 ether 00:23:32:97:7c:77
iscsi@pipboy ~ % ifconfig en0
en0: flags=8863 mtu 1500
ether 00:23:32:97:7c:77
media: autoselect
status: inactive

I was able to change the Mac
bash-3.2# ifconfig en0 up
bash-3.2# ifconfig en0 lladdr xx:xx:xx:xx:xx:xx
bash-3.2# ifconfig en0
en0: flags=8863 mtu 1500
options=2b
ether xx:xx:xx:xx:xx:xx
media: autoselect (none)
status: inactive

On 10.7.5 it worked only like this:
