Hey, thanks a bunch for this, and I figured out a way to make it just a tiny bit better. It always annoyed me that when you made a wrapper with winery, it put that ugly icon instead of the one you want. Here is a way to make the icon the Stonehearth logo (I couldn't find the actual pc .ico to convert):
6.15: Open the completed wrapper and press advanced.
6.3: Download this .icns file - https://drive.google.com/file/d/0B4_hZum8nT7ZNGJmR3BKc0RPT1k/view?usp=sharing
6.45: Go back to winery and find the Icon Browse button (should be near the bottom right)
6.6: Find the .icns file, wherever you put it, and double click it
6.75: Click install software
6.9: Keep following the rest of @Gorkiork's awesome guide!
I know its just an aesthetic thing, but I think it's a nice addition for myself, so I figured I would share it. Thanks again for the awesome guide Gorkiork
EDIT: It might not work immediately. If after you close winery and are looking at the application, and it is still the winery icon, then drag it onto your desktop and both copies should fix themselves.
