         2. Within Applications, navigate to the folder labeled "Utilities" and open the application named "Terminal.app".
         3. If you are using an Ethernet cable to connect to the network, type ifconfig en0 (for wireless, type ifconfig en1) in the Terminal window and press Enter.
         You will see a few lines of information pop up in the window. It will look something like this. Look for the line starting with "ether" and then followed by a series of 12 hexadecimal digits separated by colons. You will find your address in this line.
