The Mac version is basically just missing the audio files. I solved this by downloading the WINDOWS version to my Mac, going into the folder and copying the sound files, then pasting them into the relevant folder on the Mac version. To do this I had to right click on the Cinco Paus file and 'open package content's then find the matching folder - on Mac it's 'contents' then 'resources' then 'data' then 'sound'. It worked for me!
