Carrara 8.5.423 runs a-ok on Yosemite for me.

Vue is rich in features and abilities plus it has a nice community around it. Like Poser or Bryce, it's content manipulation program, not a content creation program - only primitive based modeling. (and of course, terrain sculpting) The shaders are awesome.

Vue's interface is easier to understand than Blenders in my opinion.

I don't know if you build your own models or use existing ones. If you don't need to model, Vue is more mature from an Enthusiast or Hobbyist level in terms of ease-of-use. Oh, and if you have Poser, it functions like a plug-in with view, letting you bring in Poser content and animations if you desire.
