What does 'MAC' description mean in the context of a MacBook?

Another meaning you may see on your computer: In networking, MAC can also mean "media access control":

Looks like this in macOS 15 Sequoia under Settings... > Network > Wifi > Advanced:

• If you are describing the Apple brand, it's Mac, formerly "Macintosh" which lives on as the default name of a Mac's startup device "Macintosh HD".

Even "HD" is no longer appropriate since Apple no longer build Macs with hard disk startup drives but decades of ingrained terminology are difficult to change, even at Apple.

• If you are describing the networking term, MAC is an acronym for Media Access Control which is almost always used in conjunction with "address" since media access control itself is just a networking concept. Like other networked devices all Macs have a MAC address — different ones for each one of its network interfaces (Ethernet, Wi-Fi, BT for example) — but the term itself has nothing to do with Macs.

Mac is a brand of personal computers designed and marketed by Apple since 1984. The name is short for Macintosh (its official name until 1999), a reference to a type of apple called McIntosh. The current product lineup includes the MacBook Air and MacBook Pro laptops, and the iMac, Mac Mini, Mac Studio, and Mac Pro desktops. Macs are currently sold with Apple's UNIX-based macOSoperating system, which is not licensed to other manufacturers and exclusively bundled with Mac computers. This operating system replaced Apple's original Macintosh operating system, which has variously been named System, Mac OS, and Classic Mac OS.
