MacWrite
MacWrite was a WYSIWYG word processor application released along with the first Apple Macintosh systems in 1984. Together with MacPaint, it was one of the two original "killer applications" that propelled the adoption and popularity of the GUI in general, and the Mac in particular.
MacWrite was spun off to Claris, who released a major update in 1989 as MacWrite II. A further series of improvements produced 1993's MacWrite Pro, but further improvements were few and far between. By the mid-1990s, MacWrite was no longer a serious contender in the word processing market, and development ended around 1995.
History
Development
When the Mac was first being created, it was clear that users would interact with it differently from other personal computers. Typical computers of the era booted into text-only DOS or BASIC command line environments, requiring the users to type in commands to run programs. Some of these programs may have presented a graphical user interface of their own, but on the Mac, users would instead be expected to stay in the standard GUI both for launching and running programs. Having an approachable, consistent GUI was an advantage for the Mac platform, but unlike prior personal computers, the Mac was sold with no programming language built-in.
