# User Experience with Managed OS for iOS, iPadOS and tvOS

> See what happens on iPhone, iPad, and Apple TV when Managed OS triggers an update. Understand notifications, installation prompts, and enforcement.

<Callout icon="apple" color="#B84A7A" iconType="regular">This guide applies to iOS devices, iPadOS devices, and Apple TV</Callout>

Iru Endpoint's Managed OS leverages native, built-in notifications and the familiar OS update experience you're already comfortable with. To avoid interruptions to your work, it's essential to understand what you'll experience with Managed OS. For Mac, see [macOS Managed OS User Experience](/en/endpoint/devices/macos-managed-os-user-experience).

### Upcoming Update Notifications

Once Iru Endpoint has cached an update on your device, you'll see a red notification badge on the Settings app indicating that an update is available.

You'll also see a message at the top of the Settings app:

If you tap on that message (or navigate to **Settings > General > Software Update**), you'll be able to proceed with the update before the enforcement deadline:

### Update Experience

Once the enforcement deadline is reached, your experience will vary depending on whether a passcode exists on the device:

* Since tvOS does not support passcodes, the update will be installed immediately, and the Apple TV will reboot.
* iOS and iPadOS devices that do not have a passcode will behave the same way as tvOS.

<Warning>
  Once devices without a passcode reach their enforcement deadline, the device will restart without warning and begin the update process.
</Warning>

### Unique Update Prompts for Passcode-Protected Devices

iOS and iPadOS devices that are protected with a passcode require that you enter your passcode to authorize any operating system update. At the Lock Screen, you'll see a notification:

Once at the Home Screen, you'll first see a Software Update prompt giving you the ability to start the update immediately or later:

If you choose to proceed with the update, you'll be prompted for your passcode and the update will be installed right away.

If you instead tap **Later**, you'll be asked to enter your passcode to authorize the update to happen overnight.

At the bottom of that screen is a **Remind Me Later** option to further defer the update:

You're allowed to defer the update just three times. After a third deferral, you'll be forced to update your device before continuing to use it:

<Note>
  This three-deferral limit for MDM-initiated updates is new in iOS 15 and iPadOS 15 and later and is enforced across a device restart. Previous versions did not limit the number of deferrals.
</Note>

Once you enter your passcode to allow the update, your device will apply the update overnight.
