I have installed the new OS on my macbook. After BigSur is running spine isnt´t able to start. Maybe it's just a coincidence and not due to the OS!? I don´t know. What can I do? I need my spine again!

Thank you Nate. Now everything works fine!!
Cool, glad you worked it out! I would have of course been happy to provide more assistance if the troubleshooting page was insufficient, but it's nice it was enough.
