We raised the minimum to GL 2.1 in Blender 2.77, and dropped support for older GPUs (pre-2012 Intel mostly). On Windows you get a popup message, but on Mac we simply crashed. Every Mac has a builtin software renderer for GL 2.1 so let's use that when the GPU is not capable! Run blender --debug-gpu to see version detection & software fallback.
