UltraScope

Hello.
I've tried to connect the Black Magic 2.5 K with a thunderbolt cable to my computer Mac X Mountain Lion. Do it have to appear on the desktop ? I would like to know why UltraScope isn't working. When I click on the application it says: Startup Failed. UltraScope could not configure the capture hardware.
What do I have to do ?
Thanks.
