I long for the day and can’t wait for GEMCAD to be programmed to MAC. It has in the past been downloadable using crossover “Bootcamp”. It does put stain on the Mac and heats up more than it should. The better option is to just buy a Microsoft Windows Operating System laptop and dedicate it just for GEMCAD. From my experience that is the better option! GEMCAD has revolutionized the gemcutting industry and I would not be without it!
