Rhino 6 for mac_Messy Lines showed in SHADE view

Messy lines are shown in the SHADE view around booleaned surface. Is there any way to close them. I tried to adjust the Display Options, but not helpful…

Can you run SystemInfo in Rhino and post the results here?

Thank you for the reply! It’s attached below.
