Sure thing. I am running an older, upgraded mid-2012 MacBook Pro with Mojave version 10.14.6 (fully up-to-date). When I try to launch the game in the Itch app, I get the following error: "JSON-RPC conversation cancelled". When I look at the downloaded app, the icon has a 'no' symbol (circle with a stroke through it). When I click on it to launch directly from my computer, I get the error "You can't open the application "Ring of Fire Prologue" because it may be damaged or incomplete." I checked the file size and it says it's "481.3 mb on disk". I have tried to reinstall it via the Itch app. I have also uninstalled it via the Itch app and re-installed it. Neither worked.
I hope that helps. Thanks!
