I have committed preliminary Mac OS support to the branches/macos folder in subversion. I am starting a new topic because the old topic has a bunch of discussion which isn't relevant now.
Things which aren't currently supported:
* WinForms integration, including GLControl
Things which are supported:
* Game window creation
* Keyboard and mouse events
* Enumeration of supported display modes
OpenTK Example results on my machine are listed below. My machine is a Mac Mini, with OS X 10.4.11 installed. Graphics card is a built-in Intel GMA 950.
GLSL 1: First shader: Works, but gives message about requiring OpenGL 2.0
GLSL 2: Julia set: Gives message about requiring OpenGL 2.0, then black screen with FPS counter
OpenAL: Playback: Works
OpenGL 5: Vertex arrays: Null reference exception
OpenGL: GLU Tesselation: KeyNotFoundException is thrown
OpenGL: Simple FBO: Works (I am unsure if the resulting image is correct though)
Test: Audio Context Test: No error message.
Test: GameWindow states: Fullscreen min/max not implemented.
Test: Input Logger: Works okay if you click on the "hidden input window" at first. If you click on anything else, it stops working.
Test: Math speed test: KeyNotFoundException is thrown
Test: Resolution changes: Not supported yet.
Tutorial 1: Simple Window: Works
Tutorial 2: Immediate mode: Works
Tutorial 3: Display Lists: Works
Tutorial 3: Fonts: Works
Tutorial 4: Text: Runs, but text layout is messed up, except for FPS counter.
Tutorial 5: Texture mapping: Works
Tutorial 8: VBO's: Works after message about needing OpenGL 1.5.
WinForms 1: Runs, but no colors appear.
WinForms 2: Runs, but no response to input.
WinForms 3: Works
WinForms 4: Runs, but nothing appears in controls.
The KeyNotFoundException appears to be a bug in the CarbonGLNative window, so I will need to examine that more closely. Kamujin, if you can run the examples and let me know if you get the same results that will be helpful.
I've also done some refactoring in the library in how platform specific classes are instantiated.
