Errors in standard output

These are the errors I got while starting the game:

Shaders related:

I have an intel GPU that is only capable of OpenGL 2.1.

My computer running macOS shows the shader related errors with different output and the others with the same exact output.

After those changes only the shaders related messages remain to be tackled.
