ACTIVE NETWORK SERVICE (e.g., Wi-Fi)

networksetup -listallhardwareports | awk -F': ' -v v="$(scutil --nwi | grep -v utun | awk '/IPv4/{i++}i==2{print $1;exit}')" '$0~v{print a}{a=$NF}'

ACTIVE MAC ADDRESS

networksetup -getmacaddress $(scutil --nwi | grep -v utun | awk '/IPv4/{i++}i==2{print $1;exit}') | awk '{print $3}'
