I tried installing the mod on my mac (using the Merge option as otherwise it totally hoses the game otherwise) and it doesn't work.
Oh, and before we get into the whole 'I don't know MacOS' song and dance I play these games through WINE rather then using the Mac specific version so asside for some little quirks WINE has the game is behaving exactly as it should on a Windows OS.
Sorry if that last part came off as little crass but I am sick and tired of the 'I don't know MacOS' tap dance when I specifically state I play the game via WINE; it's like the only WINE the programmer is aware of is the one that goes with Cheese
Now if WINE was some new program I could understand but it has been around since 1993 and is
the program of choice to run Windows programs on Linux-like OSes and the Intel Mac-OS without installing Windows.
From my experience Ren'Py plays very well with WINE (though the first time you start up a game it takes a while to load) and the only times it has gone off the rails is when somebody added into some non Ren'Py plug-in to the game. That said there are things WINE does not handle well at all - anything with DirectX, anything that make very specific calls to the Windows OS, and anything where the programer was making use of undocumented features (likely to get clobbered in the next Windows update
)
