Hiya!
Here are the instructions on how to convert and this game on Mac:
1. Download an older version of he game for mac. For instance this compressed one:

2. Download the game for Windows.
3. Right click on the Mac app and you will get the option to see the package contents. Click on "Show Package Contents".
4. Go to "autorun folder": Contents>Resources>autorun> and delete everything inside. Do not close the window.
5. Using a different window unzip the game for windows and check the contents. You should have multiple files. Move all the content to "autorun" folder in the Mac app package.
5. Inside the "autorun" folder you will see many files and folders. You can delete the lib folder and the game and renpy folders, exe (windows) files.
6. You must remove most of the folders and files into "game folder". In the end you will have 3 items: the "SunSity.py" file, "game" and "renpy" folders inside "autorun". All the remain files must be moved to "game" folder. Attention: There is already an "npc" folder inside the game folder, so move its file inside instead (clothe_decals_list.pkl). You must have one single npc folder inside game folder with two files: 1.txt and clothe_decals_list.pkl.
6. It's almost done and the game should be loading at this point. But there is a bug in the game and an error with the location of files. There was a fix created for that and shared before. Download this fix for Mac here:

7. Move the fix_mac.rpy file to the "game" folder. You can save this file also somewhere else for future versions of this game.
Bob69 if you could share the new compressed version for windows...
