This is a fork of espes' excellent Terraria Mac Wrapper, I have taken his original work and updated it to work for 1.1.2. This is still about 90% his work so he deserves a lot of the credit. You can find the thread for the original here http://www.terrariaonline.com/threads/terraria-mac-wrapper.15236/ Instructions: Download the wrapper http://www.mediafire.com/?gj7ju4pt341k6bc http://www.filedropper.com/macterraria-112_3 Steam for OS X must be installed and you have to have logged in at least once Your Steam profile must be publicly visible. A good indicator is to visit https://steamcommunity.com/ and do a search for yourself. You must, of course, own a copy of Terraria on Steam Find your copy of Terraria.exe and its associated Content folder. There are two ways of doing this: If you have access to a Windows computer you can install Steam and find it at the following path Program Files\Steam\steamapps\Common\Terraria\ Or you can use the following trick with Steam for OS X http://www.terrariaonline.com/threads/terraria-mac-wrapper.15236/page-75#post-1153215 When you start the wrapper for the first time it will ask you where your Terraria.exe and Content folder is. Play ATTENTION: I will no longer be actively supporting this wrapper. I may continue to provide help through this thread but I work a full-time job and study at university when I'm not working so I make no promises. Known issues: Some crashes when using multiplayer Dead keys are not supported in text input If you encounter a crash, here is the way to submit a report: Open /Applications/Utilities/Console.app Click "Clear Display" Run Terraria and reproduce the crash Copy the contents from Console.app and paste in http://pastebin.com/ Post a reply here with a link to the report on pastebin along with instructions on how you reproduced the crash. If you are on a version of OS X other than 10.7.2 that would be helpful to know as well. Here is the source code for the wrapper, provided under the MIT license: http://www.filedropper.com/macterraria-source No support will be provided for the source code. You will also need espes' original wrapper to get the source for the relaunch command-line utility and for the sound bank tools.
