Sorry, didn't see your post regarding the Mac. There is a 1.2 build for Mac, see forum header regarding news above. I am on a PC so I can't tell you how it works. It may be a maintenance release to run with SUv8.
Btw, when I first used v2, I had some difficulties when rendering models textured to render with v1. But once you understand the differences in rendering with v2, you can texture your Su models accordingly. With some old models, I had to go back to the model, and make various textures unique in order to get the effect I was looking for.
