    When you initiate an upgrade, your Mac will download necessary components and will need to restart to perform the installation. Before proceeding, save your current documents, quit any open applications, and copy all files and user data to another computer or backup drive. If this is a laptop, please connect to a charger at this time. This process could take an hour or more to complete and your Mac will be unavailable during this time.

  5. Self Service will prompt you one last time before it will initiate the upgrade. You cannot downgrade to a previous operating system once you upgrade.
