Blue screen for a split second on standalone launch

My mac app standalone build is showing a blue screen for a split second before launch. Then everything is fine. Does anyone have any ideas as to why it's doing this. I noticed a scene called "scene0" shows up during the build loading bar, however, this scene does not exist in my project.

Thoughts?

Thanks!

 

I am just guessing here, but is it possible it is the "Made with Unity Personal Edition" scene? That scene has a cornflower blue color and is hidden in project.
