Not able to install Parallax Previewer

Hi I am trying to install parallax previewer(Beta) in my new Macbook pro with 10.10.5.

I get an alert "This software is not supported on your system."

I'm not sure if it has anything to do, but do you have the latest xCode and tvOS SDK?

I have Xcode 7.1.1 and tvOS. I am able to run tvOS sample apps also.

I'm experiencing the same issue, Xcode 7.1.1, OSX 10.11.1
