Thumbnail Images no longer displaying again on

I’ve noticed that my thumbnail images for materials and when I save a Rhino file are no longer showing up on my Mac computer. This happened a while ago and it was fixed. My guess is Apple has done something with the OS again that the folks at McNeel aren’t aware of.
Has anyone who is using Rhino on a Mac seen this phenomena?

I’m seeing the same thing. Data point No. 2!
