How to: Easily bypass all the OpenGL 4.1 errors

On OSX, the default renderer is now OpenGL Core. This uses OpenGL 4.1, and is fraught with issues at this time (at least on iMacs). The response from unity was "Use the command line option to force the old OpenGL and everything will be fine", and that is true, but it's a pain to do so on OSX.

Here's an easier method:

Load your project without any command line arguments from the icon.
Go to Build Settings and choose Player Settings.

Under "Other Settings", uncheck Auto Graphics API for Mac.
Drag "OpenGL2" above "OpenGLCore".
Save your project.
Exit unity and reload project - should say "Open GL 2.1" at the top, and Unity should be back to normal.


Done!

 

I was trying to build my game on MacOS for quite a while now, tried several things including deleting library and so on and so forth, but still, in random scenes when it comes to lightning (and reflection probes especially) Unity just hung and did not continue.

This fixed it! Thanks a lot!
