Important Considerations Before Upgrading Your Mac to High Sierra 10.13

If you're running macOS Server, there are a few key points to review before upgrading your Mac to High Sierra (macOS 10.13). This update brings significant changes to the way passwords are stored, as well as changes to file sharing and backup services.

Password Storage and Security

Running the Wiki service configures passwords to use a less secure method of storage. It's recommended that you consider moving to Google Apps or Office 365 if you're using Calendar, Contacts, and/or Mail services.

File Sharing and Backup Services

The Time Machine service has been discontinued, so it's essential to rethink your backup strategy. You can still configure ACLs using the Storage tab under the server's main screen. Additionally, note that APFS volumes cannot be shared over AFP, so if you're running file services, make sure you're aware of this.

APFS Conversion and Imaging

You can still leverage third-party tools to automate builds, but this is no longer a built-in component of macOS Server. You can run a NetInstall to install High Sierra onto clients, which includes the firmware update. However, there are caveats to imaging due to the need for a firmware update.

Upgrade and Backup Considerations

Before upgrading, make sure you have a clone of your computer. If your operating system is running on a solid-state drive, the drive will automatically upgrade to APFS during the process.

In conclusion, while updating to High Sierra 10.13 brings exciting new features and improvements, it's essential to be aware of these key changes before upgrading your Mac. Take the time to review these considerations and plan accordingly to ensure a smooth transition.
