Any work around for Mac users. I am not getting the security issue, just getting a message saying application can not open. I used to be able to play the original version, can't remember what engine it uses, but with my mac updated and that and certain other engine just don't work. I have no problems from any of the renpys just most other engines.
Yes, as far as I know the new versions of Mac OS (Catalina and up) dropped the support for some of the engine components. But no worries, there's also a Web-Browser version. It's basically the same experience as the desktop release, so please give it a go (if possible, I recommend using Chrome or Firefox).
