Manage software updates for Apple devices

Software update process

Users of iOS and iPadOS devices receive update notifications on the device and through the Finder (in macOS 10.15 or later) or in iTunes (in macOS 10.14 or earlier). Mac users receive update notifications in System Preferences.

When an iOS or iPadOS device is physically connected to a Mac, a full copy of iOS or iPadOS is downloaded and installed. But for over-the-air (OTA) software updates, only the components required to complete an update are downloaded, improving network efficiency by not downloading the entire operating system.

Finally, the user’s data volume is never mounted during a software update. This practice helps prevent anything being read from or written to that volume during updates. For more information on the security of Apple software updates, see Secure software updates in Apple Platform Security.

Note: Not all software update options are available in all MDM solutions. To learn which MDM software update options are available for your devices, consult your MDM vendor’s documentation.

Managing software updates

Managing software updates involves testing prerelease software updates (both minor and major), deploying software updates to user’s devices, and enforcing policies that mandate users update their devices. For more information, see the WWDC 2021 session Manage software updates in your organization.

macOS software updates can be managed remotely with a mobile device management (MDM) solution or locally by a standard user (unless restricted by MDM).

Managing software updates remotely: MDM administrators can control how software updates appear and automatically install and authorize software updates on Mac computers as long as the Mac is supervised. In macOS 11 or later, all Mac computers enrolled using either Device Enrollment or Automated Device Enrollment are supervised. For a supervised Mac with Apple silicon, there’s no need to lower the security threshold from Full Security. In certain testing scenarios, however, an administrator may need to change the security policy manually from Full Security to Reduced Security. For more information, see Use macOS Recovery on a Mac with Apple silicon in the macOS User Guide.

Managing software updates locally: A local Mac account can download a full installer by using the softwareupdate —fetch-full-installer command in Terminal. Combo updaters are no longer available. On an Intel-based Mac, this download requires that you have an administrator account.

For a Mac with Apple silicon, authentication requires one or both of the following:

An MDM bootstrap token for automated, noninteractive updates

This feature requires macOS 11.2 or later, and the update being installed must be signed by Apple.

A user password for local, user-initiated, interactive updates

Updates appear in System Preferences.

Caching Apple software updates

Software updates for Apple devices can be cached on a Mac running macOS 10.13 or later with Content Caching turned on. This means that the devices don’t need to redownload the necessary update over the internet; however, the devices still must contact Apple servers to complete the update process. For more information, see:

MDM software update commands

The MDM software update commands are listed here.

Schedule an update scan

Requests that the device perform a background scan for operating system updates.

For more information, see Schedule an OS Update Scan on the Apple Developer website.

List available updates

Queries the device for a list of available operating system updates. In macOS, the command ScheduleOSUpdateScan must be performed to update the results returned by this query.

For more information, see List the Available OS Updates on the Apple Developer website.

Schedule an update

Allows the server to schedule an operating system update.

For more information, see Schedule an OS Update on the Apple Developer website.

Queries the device for the status of software updates.

For more information, see Get the OS Update Status on the Apple Developer website.

Note: The MDM operating system update commands don’t allow for customized user-facing notifications.

Testing software updates

You should develop a plan for testing updates in your environment. This includes two paths: testing minor updates (such as iOS 14.7 , iPadOS 14.7 or macOS 11.6 ) or testing major updates (such as iOS 15 , iPadOS 15 , and macOS 12.0.1 ). These tests should involve networking, app usage, and integration with any Identity Provider (IdP) systems. In macOS 12.0.1 , install a beta update of macOS to test (already supported on iOS and iPadOS).

Deferring software updates

You can prevent devices from offering over-the-air software updates to users until a specified period of time has expired since those updates were published by Apple. For example, suppose you have an iPhone fleet running iOS 14.5 , and you’ve applied a deferred software update payload of 90 days to all of them. In this scenario, iPhone users began to have iOS 14.6 offered to them on 08/22/2021, because 90 days had passed since the iOS 14.6 update was publicly released by Apple.

When you implement this restriction, the default delay is 30 days since update publication before the update is visible to managed supervised devices. However, you can specify a custom value, anywhere from 1 to 90 days. This delay applies to all operating system updates, although MDM has the ability to send specific updates to devices irrespective of the above restriction. Deferring software updates is available in iOS 11.3 or later, iPadOS 13.1 or later, macOS 10.13 or later, and tvOS 12.2 or later.

Note: Over-the-air software updates are typically available for up to 180 days after their initial availability to ensure that an update is always available for devices with the maximum deferral value.

A configuration profile can be created for each of the restriction settings listed here.

Operating system version

Set deferral length (in days)

macOS 11.3 or later

Defer major releases

Next major macOS version

macOS 11.3 or later

Dates of software update release, visibility to the user with a 90-day deferral, and when the update expires.

iOS, iPadOS, tvOS

User can see update after

Installing software updates

To help ensure that only Apple-signed code is being installed, the Apple software update process uses the same hardware-based root of trust used by secure boot. The Apple system software authorization process ensures that only copies of operating system versions that are actively being signed by Apple can be installed on iOS and iPadOS devices, and on Mac computers with the Full Security setting configured as the secure boot policy in Startup Security Utility. This process allows Apple to stop signing older operating system versions with known vulnerabilities and so helps prevent downgrade attacks.

iOS 15 , iPadOS 15 , and macOS 12.0.1 allow an MDM solution to calculate update applicability in a timely and accurate manner as soon as an update is published. For example, MDM can request a specific macOS version when sending a ScheduleOSUpdate command, and then devices can get available updates through a query to the Apple Software Update server.

Current install actions include the following:

Earliest supported operating system

Software update support

In iOS, iPadOS, and tvOS, install a previously downloaded software update.

In macOS, download the software update and trigger the restart countdown notification. The bootstrap token can be used for macOS.

Download or install the update, depending on the current state. MDM administrators can check the UpdateResults dictionary to review scheduled updates.

Perform the default action, and then force a restart if the update requires it. The bootstrap token can be used for macOS.

Important: InstallForceRestart may result in data loss.

Download the software update and install it at a later time. The bootstrap token can be used for macOS.

Download the software update and notify the user through the App Store.

Download the software update without installing it.

Software updates when connected to a Mac

When an iPhone, iPad, or iPod touch is physically connected to a Mac, a full copy of iOS or iPadOS is downloaded and installed. But for over-the-air (OTA) software updates, only the components required to complete an update are downloaded, improving network efficiency by not downloading the entire operating system. When connected, users are notified of updates through the Finder (in macOS 10.15 or later) or in iTunes (in macOS 10.14 or earlier). You can prevent this by using an MDM restriction to disallow pairing with a computer.

Managing macOS software updates

In macOS 11 , many changes were introduced to software updates to make that mechanism similar to that of iOS and iPadOS. When updating software, the updater makes changes to the operating system even before a restart. This approach significantly reduces Mac downtime during the update installation. Additionally, the user’s data volume is never mounted during a software update. This helps prevent anything being read from or written to the volume being updated.

A configuration profile can be installed on Mac computers to enable the following automatic options:

Background check for macOS software updates

Download and installation of XProtect, MRT, and Gatekeeper updates

Download and installation of automatic security updates

Download of macOS software updates

Installation of macOS updates

The Mac checks for updates about every 6 hours, and the update is scheduled for an automatic installation if the Mac meets the update criteria—for example, if it has only a limited number of processes running and either has a battery percentage of 50% or is connected to power), even if the notebook’s lid is closed. After the update has been downloaded and prepared, a 60-second countdown begins. The notification for installation bypasses Do Not Disturb, and the installation can be canceled by the user during the countdown.

Managing iOS, iPadOS, and tvOS software updates

In iOS and iPadOS, updates are offered to users as part of the standard notification process and in the Settings app. If a device is assigned in Apple School Manager or Apple Business Manager, users won’t need to review and accept updated operating system terms and conditions to complete the update. If there is no passcode on the device, you can complete the installation remotely using your MDM solution. If the device has a passcode, after MDM sends the update to the device, the device queues the update and the user is prompted to enter their passcode in order to start the installation immediately or defer for an overnight installation.

In iOS 14.5 or later and iPadOS 14.5 or later, you have the option to either update to iOS 15 or iPadOS 15 (the next latest major version) or continue to update to newer, minor versions of iOS 14 and iPadOS 14 , even after iOS 15 and iPadOS 15 are released. This allows users to still benefit from important security updates while you work to approve the latest major release for production in your environment.

MDM vendors can use three values to manage this feature for devices enrolled in MDM. A new Settings command with a SoftwareUpdateSettings dictionary contains a key (RecommendationCadence) with three values:

0: Shows both options (the default).

1: Shows the software update with the lower version number, if available.

2: Shows the update path for the operating system that has the higher version number.

Enforce software updates

For greater control, you can force a software update for macOS 12.0.1 by specifying the number of times a device should prompt to install before the update is enforced. You specify the number of times using the InstallLater MDM command, where this number is defined by the MaxUserDeferrals key.

The install notification is shown once a day. If the notification is ignored or not seen due to Do Not Disturb, the update won’t install that evening. The final notification for installation bypasses Do Not Disturb. The user has the following options for the update after they click the notification:

Install Now: Downloads the update and installs it immediately

Try Tonight: Downloads and installs later in the evening

If the user selects this option, based on machine learning from the data over the last 21 days, the Mac finds the best time to download and install the update—roughly between 2:00 AM to 4:00 AM (It may not always be during this time).

Remind Me Tomorrow: Defers the update until the next day

To force apps to quit for a software update, use the InstallForceRestart option with the InstallASAP install action. InstallForceRestart is activated after the maximum number of deferrals has been reached. All apps on the Mac quit, even if documents havenʼt been saved. The software update requires that the notebook Mac have a battery percentage of 50% or be connected to power.

Note: All install actions that initiate an installation in macOS 12.0.1 or later support the use of the bootstrap token for authentication on Mac computers with Apple silicon.
