Apple periodically makes available updates and upgrades, for macOS and its built-in apps, including Safari, directly to Macs in the System Preferences Software Updates setting. Currently, macOS prompts the user with a notification which the user can defer repeatedly until the next time the computer is rebooted.
The Nudge notification appears in addition to macOS notifications and prompts Princeton macOS users when it is time to update their macOS software. Compared to older methods of auto-installing macOS updates and prompting for a restart, Nudge takes a lighter, less intrusive approach.
In April 2023, the Nudge app will be deployed to all University managed macOS devices running macOS 12 Monterey or later — if they are enrolled into Jamf. The rollout will occur in phases based on operating systems, starting with Ventura.

What you need to do
When a new macOS update is available, you will be prompted to install the update. The notification will display the required new macOS version, your current macOS version, and the remaining days until the update deadline. You can start the update by clicking the Update Now button. Update prompts can be deferred and once the update deadline has passed, deferrals will no longer be permitted.
Next steps
The Nudge installation will occur automatically in the background. You don’t need to take any action. When an update is ready, follow the prompt to keep your macOS device up-to-date.
