In the very near term, I'd settle for MacOS Catalina (10.13) compatibility as close to Apple's final release date as possible. And a port to iPadOS, but that's a dream that's not ever going to be likely. LOL

I'm still running Poser Pro 2014 and will look forward to the next release of whatever follows Poser Pro 11. Until I upgrade to PP 11, I don't feel like I can recommend anything other than my initial request (Catalina compatibility) without the experience of 11.
