Do not install macOS Ventura v13

Dear Mac users,

As announced on Oct. 26, 2022, macOS Ventura v13 is being tested and is not yet certified for Fermilab use. Please don’t install macOS Ventura v13 until we notify you that it is certified.

This upgrade should be suppressed from appearing on Fermilab-owned Macs until it is certified for use. However, the Ventura upgrade may still appear on some lab-owned Macs.

If you are running macOS Monterey (v12.x) and see an upgrade notification for macOS Ventura, please don’t click the “Upgrade Now” button. To perform other required updates, click the “More Info…” link in the “Other updates are available” section and then click the “Install Now” button.

If the macOS Ventura banner does not appear, you should see any available updates in the main Software Update window. You can click the “Update Now” button to make those updates.

 

If you are running macOS Big Sur (v11.x), you will see an upgrade banner for macOS Monterey. You might also see an upgrade banner for macOS Ventura. If you see the upgrade banner for macOS Ventura, please don’t click the “Upgrade Now” button. Updates for Big Sur will always appear in the “Other updates are available” section. To install these updates, click the “More info…” link and then click the “Install Now” button.
