I wanted to try out the MonoGame framework, which allows for creating cross-platform games based on the XNA API. It wasn't straightforward for me to run a Mac example (on OS X Mountain Lion). There were a number of steps I had to go through to get things working, including combing through forum posts. The official instructions didn't seem to work, or I couldn't find the most recent instructions. It's for situations like these I wish I had the foresight to journal my progress so that others don't get tripped up. Here are instructions I followed in case someone finds them useful.
- Install Xamarin Studio and the specified dependencies (mono, gtk+).
- Install the MonoGame project template for Xamarin Studio
- Install XCode from the Mac App Store.
