I encountered the same problem.
I currently run FH on Wineskin Winery, and it is very effective. It runs as if it was on Windows, and you can install textures/items/maps on it, all the goodies.
My tutorial has a bit more stuff to read than Moontwist's. So beware XD
The link to WW download:
Cheesecake is taaasssttyyy (http://wineskin.urgesoftware.com/tiki-index.php?page=Downloads)
-Once it's downloaded, you will have to download the Windows FH Setup.
-Open Wineskin Winery once FH has finished downloading. Click the + button at the bottom of the long, greyish box, beside the - button and above the "Wrapper Version" text.
-Once + is pressed, a window that reads "Add Engine" will appear. Select the latest version of Wineskin. The versions will look like this~ WS9Wine1.(Version Number) example: WS9Wine1.9.9.
-Click "Download and Install" and wait until it has finished.
-Once it has finished, the main Wineskin window will show. At the bottom, click "Create New Blank Wrapper".
-A small window named "Create a Wrapper" will appear. Name it "FeralHeart", and click OK.
-It will say "Wineskin Winery is currently busy, please wait."
-Once the wrapper is created, click "View Wrapper in Finder". You will see a little window, with "Wineskin" in it. Click that.
-This is where the FHSetup.exe is required. A small window with four options will appear. Select the "Install Software" option. Then click "Choose Setup Executable".
-Go to downloads and choose FHSetup.exe. Wait a tiny bit.
-Then the FH Setup Installation window will pop up.
-Then...you know what to do next xD
Also, when near the end of installation, select "Light" instead of "Full". That way FH will not crash as much.
Hope this helps! ;)[/color]
