For what it's worth....  I am not associating Carrara 8.5 with 'very buggy', so I don't know where that came from. But I'm on WIndows 7 and 8.1, I don't know how the Mac version compares.

PS: I also still keep and occasionally use Carrara v8.x, not sure why but like you said, it just works. (too).
