Why are you removing the Mac downloads for your games? That's the only way I can play them. It's still possible to play Ren'py games on OS X Catalina
I'm not publically posting my VNs as having Mac support, as games need to be notarized to run on newer Mac OSes (to my knowing), and I don't have the funds or the means to do that. However, I still build my VNs to be compatible with Mac, and all the builds I upload on itch and Steam have Mac functionality. They should be playable on older Mac OSes, but I don't want to risk advertising them as being compatible on Mac when I know they're not compatible on every OS.
You can still try downloading Lynne to see if it works on your Mac, though. It might, even though it's not advertised as such.
