How To change a MAC address on OSX

List all interfaces by running the command ‘ifconfig’ in a terminal. Pick the interface you want to change e.g “en0

To set a different MAC on the interface run:

sudo ifconfig [interface] lladdr [MAC]

e.g: sudo ifconfig en0 lladdr dc:03:be:a0:a5:ab

You can generate a random MAC by running:
openssl rand -hex 6 | sed ‘s/\(..\)/\1:/g; s/.$//’
