on our mac mini 2016, late 2014, memory 16GB, 3Ghz i7, Intel Iris Graphics 1536MB, running OSX High Sierra - Rhino mac 6.26 crashes when entering in Raytraced Mode.
Every time, even when we do a new scene and just design a simple cube. This problem is not connected to any particular file.
Is there anything preventing you from updating to Catalina?
It appears that supporting High Sierra is increasingly getting more difficult, if not impossible.

On this computer I am running a specific version of a furniture software which will not run on newer OSX. That is why I cannot update this computer now.
I have an other question:
Why is the minimal line width in wired mode so thick (talking about Rhino 6)?
Happens only on our two mac minis with the specifications I did write on my comment before. One is running High Sierra, the other is running Catalina. Makes no difference.
This is setting
Display Mode > Wireframe > Objects > Curce Width to 1 (which is the minimal one)
