Rather than being released with Windows product release typically in the Spring, the AutoCAD for Mac relies on many key enhancements of the Mac OS X so it makes perfect sense to release closer OS X when possible. It's that time of the year when a new version of the Mac Operating System OS X 'Yosemite' is nearing release and we at Autodesk release a new AutoCAD for Mac version 2015 codename Lightsaber.
