According to the readme, I am supposed to
- Shutdown MonoDevelop
- Find your MonoDevelop AppBundle
- Right Click on it and select "Show package Contents"
- Press Alt and Drag and Drop the directory MonoDevelop.MonoGame.2.5 into ../Contents/MacOS/lib/monodevelop/AddIns/
Which I did - but I still don't see the project templates in MonoDevelop. I also looked at these other questions here, here and a few more on google - but didn't find that anyone got the templates to work (most of them used workarounds that involved hand-editing other such template projects or editing a MonoTouch OpenGL project).
Any help will be much appreciated, thanks!
