I wasn't able to test them since I own neither
Ok I might test the Linux version but I don't have a mac
the Linux program starts on Ubuntu if you run 3 commands
cd pathtogamefolder
chmod +x cmmm_plus.x86_64
./cmm_plus.x86_64
(replace "pathtogamefolder" with the path to the game folder)
Edit: saving doesn't work
