Dear Mac users,
WHAT ARE WE DOING?
Computing will be enabling security updates for Mac computers running macOS Big Sur v11, Catalina v10.15 and Mojave v10.14.
For additional information about macOS updates, please see https://fermi.servicenowservices.com/kb_view.do?sysparm_article=KB0011722
WHEN WILL THIS OCCUR?
Monday, Sept. 20
WHAT IS THE IMPACT TO YOU?
Alerts announcing the availability of the security updates for manual installation will appear on your screen.
WHAT DO YOU NEED TO DO?
• Proceed with the installation when the alert appears on your screen.
• If an alert does not appear, you can check for updates manually by clicking “Software Update” in “System Preferences.”
• If you do not receive the alerts and the security updates do not appear after the software update check, please contact the Service Desk for assistance.
• Automatic installation will begin in 28 days.
If you have customized the configuration of your Mac to allow incoming SSH:
• Some updates from Apple may overwrite existing macOS system configuration files. This may cause a Mac with certain custom configurations to violate OS Baseline and be blocked from the network. Updates initiated through Jamf Self-Service will back up the existing SSHD configuration file and turn off remote login (inbound ssh). You will need to review the SSHD configuration file to ensure compliance before turning on remote login (inbound ssh).
If you use Apple’s built-in macOS software update to install Apple updates and have configured your Mac to allow incoming SSH:
• It is recommended that you back up your SSHD configuration file and disable incoming SSH before installing the update.
