I didn't add a Mac build for Salome, even though Ren'py can export Mac builds, because I don't think Ren'py supports all Mac OSes, and trying to troubleshoot issues would be a bit of a pain on my end.
That being said, if you email me at ebihimes@gmail.com, I can whip up a Mac build in Ren'py for Salome real quick and send it over to you. You can see if it runs on your OS or not, and if it doesn't, you can request a refund from itchio.
