I lost most of my Python scripts when I switched to a Mac since a lot of them wouldn't work on a Mac, so I got used to it. Some still work, and I read where some of their writers are working on updating them. I don't use the Genesis figures because even with the workarounds, I still can't get them to work properly on my mac. I do use Superfly, though, and I've read that the materials do look different (not sure what a BDSF is anyway!) I use it mostly for still renders (using Superfly) and the cloth room.
I'll wait a little longer, I guess, and then give it a 21 day tryout.
