Hey everyone, So, I'm aware of how to change a Mac Address on an Apple computer using Terminal or applications like MacDaddy. I am currently running the latest version of OS X Mavericks (10.9) [Previously mistyped] For reference, here's an example of the Terminal commands I'm using: openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//' (To generate a new, random Mac Address) sudo ifconfig en0 ether 69:b5:32:54:75:38 (To change the Mac Address to the one at the end) ifconfig en0 |grep ether (To check that the Mac Address has been changed) So, no matter what I do, I cannot change my Mac Address on this MacBook Pro. It's a 2012 Retina. Any advice? I feel like my Mac Address may have been locked by some rouge IT guy.
