Need to change C2D Macbook MAC Address

[Littleodie914]

Yep, ya heard it right guys. I need to somehow change the MAC address of my built-in ethernet port. I tried using:

sudo ifconfig en0 ether [new mac address]

And the new address shows up when I run ifconfig again, but in the System Prefs it remains the old value. Any ideas? Thanks! 🙂

I believe that mac address is handled at the chipset, that's the only way that i've read that you can change it.

I'd have to read up on it more

you want to spoof a mac address?

This thread also seemed to indicate that it does not work on Intel Macs for some reason:

You checked at sys prefs that your MAC had not changed...is it possible to check at the router level using the router config tools? That would be a more meaningful inspection.

I haven't had any luck either with this. Maybe ifconfig lladdr and the like are depreciated?
