There are currently no releases for any other OS than Windows. If you can't start the game by running the .exe or .bat, you should still be able to play the game on any OS by running the jar file, providing you have java installed on your system with all the resources needed. On Mac you can use Jar Launcher to run the jar file. 
However, javafx (which plays the video clips) is often not included in the typical java installation and then the game won't work for long. 

So, if the game and videos run fine then great, have fun.
But if you are playing the game by running the jar file and videos are not playing and the game is freezing at the second therapist meeting, it means javafx is missing, which means your default JDK (java installation) does not include javafx. You could make the game run properly by seeing to it that the JDK used when you launch the game has javafx included. One such JDK is Liberica JDK which is the one used by the game and which can be downloaded here:

Make sure you download the Regular version for your system, not the "lite". During the installation, keep the suggested features on the "Custom Setup" screen. This should make it your default JDK and it should solve the video problem.
Note: If you do not download from https://bell-sw.com/pages/java-13/ and instead download Liberica JDK 13.0.2+ you need the Full version.
