Custom display question

In Rhino for Windows I have a custom display that shows one single material for all objects. I use this display also in my training.
Now a trainee (@kheeres) is not able to set this in his Rhino Mac as it is not accessible. I tried to support him, but was not able to solve the problem. Over here my Macbook Pro is too old to run Rhino 7.
