Should I Update to macOS 10.15?
As off September 2019, if you are working in the music industry you should not update to the next release of macOS called Catalina. I would recommend waiting for vendors who are working on making their software fully compatible with macOS 10.15. I did see before that different software and plugin stopped working as the vendor did need to release patches to be compliant with the latest macOS.
