This command-line tool demonstrates how to retrieve the Ethernet MAC address of the built-in Ethernet controller from the I/O Registry on Mac OS X. This is useful if you need a means of uniquely identifying a Macintosh system. Techniques shown include finding the primary (built-in) Ethernet interface, finding the parent Ethernet controller, and retrieving properties from the controller's I/O Registry entry.
