It is pretty much confirmed now that AutoCAD would soon make a comeback on the Apple Mac platform.
AutoCAD for Mac was discontinued in the 1990s after Macs were pretty much destroyed by the PC market.
With Apple making a strong comeback in the recent years, AutoCAD is all set to get back on the Mac platform.
AutoCAD developers have not stated anything but there are some screenshots of an early release that are circulating on the web.
