# source: https://www.howtogeek.com/220462/how-to-find-and-change-your-mac-address-on-os-x/

# Find MAC Address
ifconfig en0 | grep ether

# Change it
sudo ifconfig en0 ether aa:bb:cc:dd:ee:ff

# This will generate and set a new MAC address for en0 every time you run it.
# The changes made from both these commands will be reverted when you restart, so this is not permanent.
openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//' | xargs sudo ifconfig en0 ether
