Coming from the "Beyond Shadowgate" kickstarter here. Glad to discover there is more adventure games to be played here!!!
Unfortunately, I'm running on a Mac, and although it seems you support it for "Infested" (unlike "Spectacle"), it seems that at least for the latest macOS major release (macOS 13 Ventura) it doesn't work. When double-clicking it to launch it says "The developer of this app needs to update it to work with this version of macOS.".
Available for testing to help you solve this! FYI I'm a Mac developer too so I won't shy away from any tech stuff you might throw at me.
Seems others are having the same issue with Gamemaker Studio: https://forum.gamemaker.io/index.php?threads/steam-games-wont-launch-on-macos-13-ventura-but-do-work-on-macos-12-monterey.99348/
