Mac OS 10.15?

I have a commercial licence for Rhino 5 for mac Version 5.5.5. My mac is running OS 10.14.6. My mac keeps prompting me to update to OS 10.15.6. I have been putting this off for some months now and a search on the forum for OS 10.15 yields no results. Any known problems with Rhino 5 for mac and OS 10.15?

It works fine.
I updated to Catalina as of 10.15.4 and an currently on 10.15.7.
V5, V6, and V7 all work fine.

Thank you for the information.
