I’m using Rhino since 2015 on different Mac computers. Using on Catalina worked perfectly. Just did a clean install (erasing totally the hard drive before installing the new OS) and installing Big Sur for the first time yesterday.  
I installed Rhino 5 (5F96) and opens. If opening a file it crashes and quit. I can’t access preferences (it crashes). I tried opening old files or starting from blank page model. Same results.  
I’ve an iMac Retina 5K, 27-inch, 2019, 3,6 GHz 8-Core Intel Core i9, 80 GB 2667 Mhz DDR4, Radeon Pro 580X 8 GB  
Rhino 5 works for me I don’t really need to upgrade. Does upgrading would fix the issue?  
Thank you.
