My Google searches can't find an answer. Do any of the 3 configs support Open GL? I was in a Mac Store last night exchanging my faulty power supply and spent 30 minutes playing with a base spec 2011 Mac mini. I downloaded Blender3d (www.blender.org), and it ran ok - the front end was very responsive. I was not sure how to simulate a 3 button mouse with the track pad so could only do limited testing. I download the blender regression files and did a test render of an animation. It worked but the character (a dolphin) was rendered as a black blob rather than a nice shaded model. I assume this is due to the OpenGL support on the base model not being adequate. My guess it that the Dual core with the AMD Radeon HD 6630M is the only spec with any hope of running blender. The specs I have found for that card mention openGL 4.1 - but will Lion on a Mac Mini include/allow the drivers? Anyone got a view?
