I'm not entirely sure how ren'py launches on mac, but do you have the Ren'py launcher from here:
You must be registered to see the links
When you start the launcher you should see something like fig 1 in here:
You must be registered to see the links
Make sure you have this project (game) selected (sarada..) If it's not there, you have to change preferences->Projects directory to point to the directory containing this sarada game, or move the sarada game there (..and Return)
Last option under Actions is: Force recompile
If recompile is silent the game may run (try Launch Project) if an error is reported, then it may not. I got no error and it launched.
This will only work for projects if raw scripts *.rpy are included; sometimes only precompiled scripts (*.rpyc) or even archived scripts (*.rpa) are included. There are tricks to extract (rpatool.py) and decompile (unrpyc.py) those even, but i'm not sure how to do that on mac; and one of those tools also required an unicode hack.
