MacWrite and MacPaint were the only two apps that shipped on the original Mac when it was released on January 24, 1984. The Mac was a new platform. It didn’t run Apple II software or IBM PC software, or even software from its cousin, the Lisa, which shipped from Apple a year earlier. The Mac platform was a completely clean slate. So if you bought a Mac in January or February, or even March or April — all you could do with it was write with MacWrite and paint with MacPaint.
