I'm going to move this thread to the Game Help board instead of the Patch Bug Reports board, as it's not a bug related to the patch.
In regards to the tutorial Dark has supplied above, you'll have to open the file directory for FH via PlayOnMac and replace the seperate FH executable on the downloads page with the original FH.exe in the Feralheart folder.
If you need a visual tutorial I'd be happy to give one.
