Computer-aided design software.
According to internet sources, there were only three versions of AutoCAD ever originally released for Macintosh: Releases 10, 11, and 12. From about 1994 to recent times, Autodesk ignored any further releases for Macintosh until 2010. (This was likely because now everyone uses Intel processors. Why develop for 680x0 and x86 architectures when you can cheap out and just do one?)
