I'm running Sierra (Macintosh OS 10.12.6). I'm still using Poser version 11.2. Is anyone running the same version of the Mac OS I'm running, along with Poser 11.3? If so, how does Poser run? I'm just trying to avoid problems if I switch up. The thing about v 11.3 being faster with certain Windows Graphic cards would not apply to me. I'd rather be slow and have a stable version, rather than jump to the very latest.
