I have posted a few times indicating I have native Mac software for playing, visualizing, and scheduling shows that are in LOR format (sequencing I don't have done yet). I even have software that will let you build your own light curves (uses a light meter) and will display all the current light curves. I support the lynx dongle. It is native Cocoa software, that integrates with iCal, etc. However, I will stated it is far smaller in terms of breadth of support of hardware versus xLights, with the latter have far greater support (pixel net, E1.31, etc).
