Unity on Linux will be a native Linux binary. For games designed to run on desktop systems, the porting "effort" should be no more then clicking a button -- unless you use custom C++ libraries. All the game logic in Unity is implemented in mono bytecode, and the graphics already use OpenGL on OSX (you generally don't need to write platform specific shaders in Unity, as shaders are cross compiled to the target platform).
