Ogre3D vs. OpenSceneGraph vs. Irrlicht vs. Panda3D vs. Monogame vs.OpenGL Free for all

So, I need to get this figured out and soon. I am trying to decide what the best option for making a game engine for my independent study course would be. The long and short of it is that Ogre3D is working on my wife's desktop, but I cannot build it for my mac, and I need to be able to work on it wherever/whenever. So here's a grand shootout of different libraries, with all their pros and cons laid out, with my own conclusions about what I am going to use after. Disclaimer: These are basically my combined thoughts from when I tried to work with it, or from DevMaster.net. Your mileage may vary, I'm just trying to aggregate my thoughts into one spot. On with the tables and lists!

Engine:	Ogre3D	OpenSceneGraph	Irrlicht	Panda3D	Monogame	OpenGL
Pros:	Platforms: Big 3, iOS, Android, WebGL Comprehensive, has scene management, resource loading, many built in shaders Abstracts most meshing functions Has extensions for input, GUI, physics Well Documented API, many tutorials, books	Platforms: Big 3, Playstation Scene Management, resource loading Many Plugins	Platforms: Big 3, Xbox Decent Tutorials Easy to get up and running(see below)	Platforms: Big 3 Uses Python Extensively Integrated tools for physics, AI, network, Audio, packaging	Platforms: Most of them Comprehensive Uses C#, my favored language Decently supported Can use OpenGL and DirectX	Complete and total control over my engine Don't have to deal with installing except in the case of physics engine
Cons:	Poorly documented for Mac, so far impossible to set up Must use 1.7 for set up, 1.8 for manual, 1.9 for available downloads, and 1.10 for latest features. Many things for ease of use are simply missing.	Poor Community and Documentation Poor support for procedural generation	Difficult to set up on Mac Poor Documentation	Documentation lacking, especially for c++ Not easily set up on IDEs that are not Visual Studio Because it uses integrated tools and is a full-stack engine, Panda3D needs to be disqualified for my purposes.	Have to make my own WebGL support Not helping me learn better C++, which is part of this exercise Unknown how easy it will be to install BulletSharp	The very definition of going to square one Have to implement all resource loading from scratch Might be too big a scope for a 6 week project

What it really seems to be coming down to is Monogame, OpenGL, or Irrlicht. I guess the game is then to figure out which one takes the least amount of time to install and get 10 rotating cubes on the screen. Once I have that down, I should be able to figure out what the best next step is. I'll update with my results once I get it done.
UPDATE: Ditching Monogame because OpenTK's been abandoned. Ditching Ogre3D because of its documentation. Haven't set up Irrlicht yet, but OpenGL/SDL is seeming like the way to go.
