GLSL gives strange error: "#version required and missing" on mac only

I have a strange and deeply frustrating problem. I have a shader that works great on Windows and Linux. When I go to my mac it gives me terrible errors and black screen.

// C++

QGLShader *vshader1 = new QGLShader(QGLShader::Vertex, this);


    vshader1->compileSourceFile(":shaders/vert1.vert");

    QGLShader *fshader1 = new QGLShader(QGLShader::Fragment, this);

    fshader1->compileSourceFile(":shaders/frag1.frag");

    program1.addShader(vshader1);
    program1.addShader(fshader1);
    program1.link();

      

        
        
        
      

    

So basically, if I add version #version 150 or #version 410, it complains that #version is not listed. If I specify #version 130 or #version 350 it complains that I was asked to enter an invalid version (shouldn't I just go back to the available version?)

Any idea what's going on? This is especially annoying since I specified #version and I didn't use a different keyword.
