21 May 2019 Changing MAC address in org

Via Minko Gechev's tweet. Saving in an org block, just because… 

changeMAC() {
    local mac=$(openssl rand -hex 6 | sed 's/\(..\)/\1:/g; s/.$//')
    ifconfig en0 ether $mac
    ifconfig en0 down
    ifconfig en0 up
    echo "Your new physical address is $mac"
}

changeMAC

Your new physical address is aa:36:ee:d2:ee:66

ps. Also see Execute org blocks as root.
