The Mac – or “Macintosh” if we’re going back to 1984 – is the first computer to effectively market a graphical computer to the masses, all delivered by Apple (or, at the time, Apple Computer).

The Mac has gone through several stages of evolution and iteration since 1984, including the MacBook Air, MacBook Pro, Mac mini, iMac, iMac Pro, Mac Pro, Performa, Power Mac (including the G4 Cube!), iBook, and more.
