Looked around for this, couldn't find anything on point. Anyway, I'm trying to change the WiFi MAC address on my MacBook Pro, Mountain Lion. I figured out the terminal commands & got it changed, but every time I do it it automatically kills my Internet connection. I stay connected to the router, but I lose Internet. I have to reboot to regain my connection, & that of course resets the MAC address. Is there a step I'm missing? Before anyone asks - because they always do - no, you won't be helping me do anything nefarious. I was able to spoof the MAC address on my PC & I want to be able to do the same on my Mac. Thanks!
