Do not upgrade to Catalina MacOS 10.15 until we give you the go-ahead. (.2 or .3 ask after Thanksgiving)
We’ll be blunt. Do not upgrade to macOS 10.15 Catalina right away! We recommend waiting until at least 10.15.6 or mid 2020, whichever comes first. And then contact us for help with making sure Catalina won’t destroy your workflow.
