From the developer:
Osm2xp is a scenery generator for Xplane simulator. Using Open street maps data, it will generate 3D buildings into xplane, each one with its real location and real shape.
The app is using facades, which gives better fps than .obj. You can always scale the number of osm2xp buildings in xplane with the "number of objects" setting.
You may want to check out more Mac applications, such as TheTudors, OpenGeoDa or Tempus Irae, which might be similar to osm2xp.
