Your MacBook Pro's MAC (Media Access Control) address is a 12-digit number assigned to a network adaptor in order to identify itself on a network. Whether it's an Ethernet port or USB adaptor, the MAC address identifies where the connection is. If you've found yourself in the position of needing to troubleshoot your MacBook Pro's network connections and don't quite know where to begin, locating the MAC number is a good start, and it isn't as technical a process as you may think. In fact, it's relatively simple to find this number, and it shouldn't take more than a minute of your time to do it.
