## Problem OpenGOAL uses OpenGL 4.3. Apple stopped upgrading OpenGL after 4.1, so the way OpenGOAL currently works will never be playable on Macs using OpenGL. ## Solution Luckily, downgrading to OpenGL 4.1 is not a huge change (at least it doesn't seem like it to my untrained eyes). ## Changes * set hints for OpenGL 4.1 instead of 4.3 for __APPLE__ * skip the OpenGL debugging callback setup for macOS (requires 4.3) * bump down the version string for all shaders * stop using the `binding` layout qualifier in shader code * move the `flat` qualifier first (not sure if this is a 4.1 thing or just Macs being more strict) * don't mix signed and unsigned ints in shaders (not sure if this is a 4.1 thing or just Macs being more strict) * add some hacky CPP to the Shader constructor for binding texture units and bones buffers based on variable names in the shader code ## Results
