Shaders won't work on MacBook? "MSAA support is disabled on High Sierra for this GPU"

I am attempting to use a wireframe model asset, I even wrote my own, but both resulted in the same error stating that the shader was not supported on my GPU. I switched from Metal to OpenGL 4.1 and now it states "MSAA support is disabled on High Sierra for this GPU". I was wondering if anyone knows how to resolve this? I've tried disabling MSAA but I get the error still. I cannot use shaders!
