People often ask if LOR will run on Apple software. The answer? Sort of, but with some help. Light-O-Rama has to use some very low level device drivers to communicate between the computer and the various types of controllers available.  The Windows environment allows them to do this relatively easily, not so much in the Apple world. Most Light-O-Rama Apple users use their Mac in a Windows environment via Parallels (http://www.parallels.com/products/desktop/) or VMWare Fusion (http://www.vmware.com/products/fusion/overview.html). A good article showing how well these products work can be found at http://online.wsj.com/article/SB10001424052748704140104575057251096106096.html
