I am trying to locate my ethernet MAC address on a Macbook Retina 12" using
ifconfig but I can only see
en0 which should be my wireless card; it's quite baffling. Any help would be much appreciated.
MacBook Retina 12" dont have Ethernet port built-in hence en0 is your wifi. Do you use any kind of adapter for ethernet to work? If so, you can use
System Preferences > Network > (choose interface matched with your ethernet adapter) > Advanced... > Hardware. From here you can see your MAC Address easily if your ethernet adapter plugged :)
