Those of us who are working full time as music producers or audio engineers typically don't upgrade our operating system the minute a new release or update comes out.
Many of us have learned the hard way over time.
No matter how much "Apple" beta tests there will always be some compatibility issues with software or hardware when a new Operating System (OS) release or update comes out. (This also applies to the latest update of a plugin or application as well).
All it takes is one minor thing that some developer didn't take into account (or wasn't aware of) and we could be dead in the water; causing us to miss deadlines, having to recreate parts, or worse yet, entire sessions!
With "Digital Audio Workstations" ("DAW") upgrades we are cautious, knowing that, most likely, there will be hardware and/or software (plugin) incompatibilities with a new release.
Some engineers and producers NEVER...
