I'm having the same issue. And I'd love to play this game...I just can't get it to open on my Mac at all. Any solutions yet?
So...I have some data that might be useful! I was able to start the game...but did get some interesting errors that might shed light on the problem.
I right clicked on the app, then chose Show Package Contents. Then clicked on the MacOS folder, then I double clicked on the "ThePriceOfFlesh" executable. This opened up the game and two terminal windows. One the regular bash terminal...but the other was a ThePriceOfFlesh terminal window...and that window had the following messages:
[S_API FAIL] SteamAPI_Init() failed; ipcserver init failed .
[S_API] SteamAPI_Init(): SteamAPI_IsSteamRunning() did not locate a running instance of Steam.
[S_API] SteamAPI_Init(): Could not determine Steam client install directory.
So I think the trouble has something to do with the RenPy Steam integration?I kind of have the same problem. When I click the application, it opens and closes immediately, it doesn't even have the chance to show the window. I open the game from the executable file like you said, except I'm getting an error message that says:
"can't open file 'ThePriceOfFlesh.py': [Errno 2] No such file or directory"
I can open the game if I redownload the whole thing from the Itch.io page (I have it here rather than through steam). But so far after the first time I boot up the game (fresh download) and close it, it does the same thing
(Update) So I found the problem, removing the application from its file folder makes it stop opening, and I don't know why
