Comment (by mascguy):

 Great to hear Ken, we're definitely on the same page.

 Perhaps I'll try this out with Mame today or tomorrow. I'm not 100%
 certain what the minimum required MacOS version is, in terms of
 APIs/Frameworks used... so that will ultimately be a limiting factor. But
 even if it only allows us to support one or two earlier MacOS releases
 with the latest version, that's still a win for our users.

 Regardless, I'll certainly keep you in-the-loop with my findings. Thanks
 for the help/info!
