Hey I'm not familiar with the Mac version of FeralHeart, but let's give this a shot anyway. I'd love it if you could share with me some screenshots (if possible to) or pictures of your FeralHeart folder and what's inside it as I'm not at all familiar with it's appearance. Hopefully once you have done that I can possibly help you once I have gotten a visual.
To share your images with me, upload them to www.imgur.com and send the image links through this thread!
