In my experience, my macbook pro MAC address can be changed with the bash command listed in the file for wifi (sudo ifconfig en1 ether [addr]), but it will not let me change it to any arbitrary address I want, just some of them, including addresses that start with aa:[rest], ab:[rest], etc., which is what I usually go for. Just tested it and en0 doesn't seem to have the same limitations.
