OLDER VERSIONS OF MACDADDYX MAC OS X

On my MacBook Pro (which, for the record and if it matters, is running Mac OS X 10.6.7), I need to do all of the following before running ifconfig, as shown above: These can be accessed via the Network pane in System Preferences, or via the scselect command from Terminal it’s that scselect command which offers the key to changing a Mac’s MAC address. Mac OS X has a feature called “system configuration sets” or “ locations,” as it’s termed in much of the GUI. forgetting to “unstick” the current system configuration set.having the System Preferences application running,.being associated with (i.e., connected to) a Wi-Fi network with your Airport card,.having the interface “down” (i.e., if you’ve recently run ifconfig en0 down or an equivalent),.As far as I can tell, these conditions are: The thing to know is that there seem to be a number of conditions that will prevent Mac OS X from successfully changing a NIC’s MAC address. Ifconfig | grep ether # Confirm change but uh-oh! Output is the same as before! Why? Sudo ifconfig en1 lladdr 00:00:00:00:00:00 # Try changing MAC address for en1 (usually Airport) Just like others, whenever I tried to run the above command, nothing seemed to happen: ifconfig | grep ether # Determine current MAC addresses I ran into a similar problem not long ago when my MacBook Pro didn’t do what I expected. There are numerous blog posts all over the ‘net that tell you this time and again, but each one seems to have comments from users complaining that it doesn’t work on their system. This should be really simple, as the correct command line is plain as day (where the string of colon-separated 00’s is your preferred MAC address): sudo ifconfig en1 lladdr 00:00:00:00:00:00 link-level address) of a network interface card. Another is changing the “Ethernet ID” (aka. Changing the hostname of a Mac OS X Server is one good example. One of the oddities of Apple’s Mac OS X platform is that some things that should be easy are obtusely difficult, and remarkably so. Update: For users of Mac OS X 10.7 (Lion) and 10.8 (Mountain Lion), a much easier solution called SpoofMAC exists as a set of Python scripts.
