Important info for Mac players:
The Cider client WILL NOT RUN Paragon Chat. I therefore changed Island Rum to support Wine. Follow these steps:
1. Install Homebrew by visiting
http://brew.sh/ and following the instructions.
2. Once that's installed, type "brew install wine" and wait for it to install. It may ask you to install a couple of other things before it will complete its installation, but it will tell you what commands to use or where to download it from.
3. Next, type "brew install winetricks".
4. Finally, type "winetricks d3dx9 vcrun2008 msls31 winhttp".
After that, you'll have all the pieces you need to make Island Rum work with Wine (it will auto-detect it).
NOTE: Island Rum may also try to install homebrew and wine on its own. It's *supposed* to, but I've gotten mixed reports on whether it actually does. So it's safer to start with installing it yourself. If Wine is already installed, Island Rum won't try to install it again.
