I also dont use Mac so am not much help, but you should just be able to connect it to your PC via USB cable and the X-lite should switch to USB device mode and act like any other joystick/gamepad. Just make sure you turn on your X-Lite first so it doesnt start as USB storage device. I had a quick look and saw some usb videos of the older X9D working with Mac by just plugging it in, so the X-lite should also work.
Only if you want to be sick 
each time you look at the radio :P… but besides my personal opionion on the looks, I honestly dont think its a very good radio as initial reviews are all saying the gimbals are just like the ones used in the Flysky I6… a rather budget radio…
