I know that in Leo OS you can go to terminal and are able to change the system's Ethernet card MAC adress without any third party software. Just do a:
% sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

I have Tiger 10.4.11 and this does not work is so I think.

as far as the aa:bb:cc:dd:ee:ff do i just make up any number set i want to go in there? I'm sure you are dying to know why I want to change my MAC adress, no real reason I feel really protected on my University network, but would it not be smart to do this semi-regularly, say at a rate of once a year? It goes without saying that you can change it more often if you're paranoid.. but I think it's just a matter of personal security.
