you cant change your mac addy its burned into the chip, all mac addresses are unique, short of getting a new card you cant.
I am going to assume your intentions are purely honourable and that want you want to do is perfectly legal.

OS X 10.4.x (Darwin 8.x) kernel sources appear to require no modification in order to spoof MAC addresses.
So what I am asking is anyone knows the command to change Mac addy?
...
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.
...
ifconfig en1 lladdr AA:BB:CC:DD:EE:FF
ifconfig -a
You can do it with the ifconfig command in the the Terminal.
According to the ifconfig man page (type man ifconfig to get to it):
That means that to set the MAC address you'll need to type something like:
Code:ifconfig en1 lladdr AA:BB:CC:DD:EE:FF
In my Powerbook, the Airport adapter is called en1. You can check your configuration by typing:
Code:ifconfig -a
And Good luck!
It worked with the Ethernet card, but still cannot change Mac addy for Airport card
Thank you anyway
What exactly do you mean by that? Do you mean that if you run the ifconfig command again to display the MAC address that it remains unchanged? Or do you mean that it does not allow you to join the wireless network?
On my machine (Macbook C2D), the command changes my MAC address, as listed in ifconfig, and prevents me from connecting to my access point (MAC address control).
sudo ifconfig en1 ether 00:01:02:03:05:06
to change mac address on an airport card you will need this little note:
there's an app sitting well-hidden in
/System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport
(yup, need to
sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/A/Resources/airport /sbin/airport
)
simply go to that folder and do this:
./airport -z
THEN do your
sudo ifconfig en1 lladdr....
With MacSpoofer (freeware) you can easily change the mac address of the Airport card. Download it from www.macspoofer.com![]()
