Adam Engst points out the three remaining uses of the word Macintosh from Apple — the default name of each Mac’s boot drive, within the about screen for Finder, and on the back of the iMac’s retail box.
Apple hasn’t really used the term “Macintosh” in any meaningful way during my time using their products (since roughly 2004). But it is a great name and I would love to see Apple use it again. Imagine them introducing a new desktop Mac that sits between the Mac Mini and the Mac Pro with the name “Macintosh”. That would be neat.
