Sometimes it seems there is some confusion, or simply misuse of the term MAC. MAC from Wikipedia: In computer networking a Media Access Control address (MAC address) or Ethernet Hardware Address (EHA) or hardware address or adapter address is a quasi-unique identifier attached to most network adapters (NICs). It is a number that acts like a name for a particular network adapter, so, for example, the network cards (or built-in network adapters) in two different computers will have different names, or MAC addresses, as would an Ethernet adapter and a wireless adapter in the same computer, and as would multiple network cards in a router. However, it is possible to change the MAC address on most of today's hardware, often referred to as MAC spoofing. While a Mac which is short for Macintosh is a personal computer (yes a PC) produced by Apple Inc., formerly Apple Computer Inc. Macs are available in desktop and notebook versions including the Mac Mini, iMac, mac pro, MacBook and MacBook Pro product lines. However, let it also be known that while every internet equipped Mac has a MAC, a MAC is not nor should it be confused with a Mac. And if you are looking to get a Mac, the members here at Mac Rumors would be glad to help you decide which one.
