Mac install

Are there any special instructions for setting up Air Player  on a Mac ?

Just install from:
http://mediasignage.com/html/digital_signage_software.html

Please note that on Mac, we do not support (yet) the SignageController so you will loose some functionality
We recommend that you use a PC for now until Macs are fully supported.
You can our Players for 1/2 the price as a Mini Mac with an optimized XPe OS.
