When you connect a computer to a network for the first time, you may be asked for your computer's MAC address. MAC is an acronym for "Media Access Control" and applies to any device connecting to a network -- Windows and Apple alike. A MAC address is a 12-digit alphanumeric code that is unique to each network adapter. A MacBook Pro has one address for its Ethernet adapter and one for its Wi-Fi adapter. You can find either address in System Preferences in OS X Mavericks or Yosemite.
