A Fleet admin can set a minimum version and deadline for Fleet-enrolled hosts. If an end user's machine is below the minimum version, the Nudge window above will periodically appear to encourage them to upgrade. The end user has the option to defer the update, but as the deadline approaches, the Nudge window appears more frequently.
To set the macOS updates settings via CLI, use the configurations listed [here](https://fleetdm.com/docs/using-fleet/configuration-files#mdm-macos-updates).
On Intel Macs, Fleet triggers step 1 (downloading the macOS update) programmatically when a new version is available. This way, when the user arrives on the software update screen, they only need to initiate step 2.
> On Macs with Apple Silicon (e.g. M1), downloading the macOS update may require end user action. Apple doesn't support downloading the update programmatically on Macs with Apple silicon.
Currently, end user macOS update reminders via Nudge don't support RSR versions (ex. "13.4.1 (a)").
You can use custom MDM commands in Fleet to trigger built-in macOS update reminders for RSRs. Learn which MDM commands to use in the Apple docs [here](https://support.apple.com/guide/deployment/rapid-security-responses-dep93ff7ea78/web).
Sometimes after the end user clicks "update" on the Nudge window, the end user's Mac will say that macOS is up to date when it isn't. This known issue can create a frustrating experience for the end user. Ask the end user to follow the steps below to troubleshoot:
1. From the Apple menu in the top left corner of your screen, select **System Settings** or **System Preferences**.
2. In the search bar, type "Software Update." Select **Software Update**.
3. Type "Command (⌘)-R" to check for updates. If you see an available update, select **Restart Now** to update.
4. If you still don't see an available update, from the Apple menu in the top left corner of your screen, select **Restart...** to restart your Mac.
5. After your Mac restarts, from the Apple menu in the top left corner of your screen, select **System Settings** or **System Preferences**.
6. In the search bar, type "Software Update." Select **Software Update** and select **Restart Now** to update.
## End user macOS update via built-in macOS notifications
Built-in macOS update reminders are available for all Fleet instances. To trigger these reminders, run the ["Schedule an OS update" MDM command](https://developer.apple.com/documentation/devicemanagement/schedule_an_os_update).
