my customer uses Rhino 5 for Mac (5.3.2 (5D197) ) on macOS High Sierra.
Now he gets the two errors after starting Rhino.
The support from McNeel Barcelona (Verena) was so kind to help me with the tipp “Reset Rhino Preferences” from here: https://wiki.mcneel.com/rhino/mac/resetprefs
But that didn’t help.
What to try next?
