Ultra virtual sets

Is it possible to use the virtual sets that were sold by Ultra Magic. They were originally used for pc but I see some sights that are selling them for Mac(FCP). Any thoughts?

What format are they in?

Ultra is only available for Windows. I don't know of any plugins that would allow you to use these proprietary files in FCP.

My software:
Pro Maintenance Tools - Tools to keep Final Cut Studio, Final Cut Pro X, Avid Media Composer and Adobe Premiere Pro running smoothly and fix problems when they arise
Pro Media Tools - Edit QuickTime chapters and metadata, detect gamma shifts, edit markers, watch renders and more
