Unity wont render shaders?

Hi

I tried to get the reflection working for a sphere, but as it didn't work I have seen a lot of tutorials without having any good results. So i thought to myself that a good idea would be to download and import Unitys own demo scenes which demonstrates the new standard shader.
This is a screenshot from the asset store of what the scene will be looking like (1st image):

And this is what the scene looks like in my computer (mac mini 2.3 Ghz Intel Core i7. Two years old) (2nd image):


At first it seamed that I can't get the shaders to render properly.

But then, while actually writing i returned to unity to take the 2nd screenshot and while hovering the mouse pointer over the game window the scene kind of updated itself into this (3rd image):


Does anyone have an idea of what is going on here? Could this be some sort of bug or is my computer not good enough to handle these shaders?

Any help is greatly appreciated.

 

any one?

 

Did it have to bake the lighting in? Whenever it bakes lighting it also does stuff with reflection probes. Maybe it just took a long while to calculate.
