I am on a mac and I have the solution!
First of all, you need to get the FeralHeart folders, you can do this by getting the full version of CrossOver (Look around for it) Then download and run the .exe file with crossover, install it to the z drive (Mac driver) Or the Desktop, your choice, just change the folder destination Or it will glitch up D: After it installs, you should have the FeralHeart folder somewhere, Search for it on Finder, (Note that you must go into the folder to run FeralHeart.exe) Now Get your objects,Maps or anything else! And put them in the folder! Then run the FeralHeart.exe in the folder with crossover and your finished! (You must watch out because it may crash every now and then)
Hope this helps!
