As it is, DAZ is first and foremost a clearing house for props, models, surfaces, scripts, etc. The software itself has languished over the years, but is still usable. I just read about DAZ 5 today, and I can see there's a certain amount of trepidation among users. This probably wouldn't be so if a roadmap had been provided. If there is one, I couldn't find it. All this said, I like DAZ.

Today, the term "UI" mostly means appearance, so I would be surprised to see any substantial functional changes. Limited QA will make the change seem harder than it needs to be, as will the absence of professional documentation. I'll handle it. It will still beat the devil out of rentware. Or of learning Blender.

Why there would be any point to making this software available on a MAC is beyond me. DAZ will have two programs to maintain when they can hardly maintain one. But, I doubt the users will feel this pain.

Bring it!
