The purpose of this document is to supply guidance and best practice solutions to facilitate the successful silent in-place upgrade of Mac computers to the latest-available version of macOS Catalina 10.15. This workflow is for organizations that have Jamf Pro and allows users to open Self Service and upgrade with one click. The workflow takes advantage of the “startosinstall” command located in the Install macOS Catalina app (also referred to as the macOS installer).
