The Ranking: 3D Modeling Software for Mac Users This leaves us with the ultimate 3D modeling list for Macintosh users. However, we excluded software that is not available or not suitable for the Mac OS. The list of the most used 3D design software for Mac (see below) is based upon our list of the 25 most popular 3D modeling programs.
