Hey, thanks for letting me know!
Yeah, I found out towards the end of development that Godot 4 doesn't work with Mac web yet (https://docs.godotengine.org/en/stable/tutorials/export/exporting_for_web.html). However, I was able to run it from Firefox on my Mac? So if you have Firefox, that might work. Otherwise, I did include a native MacOS build that you could download if you're up for that.
I appreciate you trying and letting me know :)
