Rhino 5 on Big sur - Unhandled exception validating license?

Does anyone know how to proceed?
I just bought a new MacBook pro 16" and the Big Sur OS might be the problem here. It does not like photoshop so I’m suspecting that is where the problem lies. I’m running Rhino 5.5.5.

Thank you!

Yes, Rhino 5 for Mac is not supported on Big Sur. You’ll need to upgrade to Rhino 7 or use an older macOS that is supported for that older Rhino version. See Rhino - System Requirements for Rhino 5

Thank u! I was afraid of that.
