Create a Mac Policy to Delay or Block Sequoia

In September 2024, Apple will release the latest version of their operating system, macOS 15 Sequoia, to the general public.

Important: If you're not yet ready for macOS 15 Sequoia, there are two settings to deliver to your MDM-enrolled macOS devices to prevent it from being installed.

To fully block the upgrade to macOS 15 Sequoia, configure two settings:

  1. To prevent the update from appearing on individual devices fromin System Settings > Software Update, use Delay Major macOS Software Upgrades. Users with this policy set will not see macOS 15 Sequoia as an available upgrade.

Note:

Enforcement of this setting will depend if you're currently using Patch Management Policies:

  • If you’re using patch policies, configure this via Policy Management > Patch Management > Defer Upgrade Releases.
  • If you’re not using patch policies, configure this via the Delay Major MacOS Software Upgrades policy.
  1. Restrict the macOS Sequoia installer from running using the Block macOS Sequoia Installer Policy. Users are allowed to download the installer, but the installer will be blocked from launching. 

Prerequisites:

Delay Major macOS Upgrades

Delay macOS Upgrades Using Patch Management Policies

JumpCloud’s patch policies (Policy Management > Patch Management) help organizations manage their operating system versions, including managing new major version releases. The Major Upgrade Settings section allows you to specify a delay of up to 90 days for new major versions of macOS. See Create a macOS Patch Policy.

To add a delay, make sure Defer Upgrade Releases is selected, and then set a number of days from 1 to 90. The default is 30 days.

For each policy in your patch rings (Vanguard, Early Adoption, General Adoption, Late Adoption), update the Major Upgrade Settings if you need to delay macOS 15 Sequoia.

Important:

After macOS 15 Sequoia is approved for use within your organization, uncheck Defer Upgrade Releases and allow upgrades to proceed as normal.

Automatic Action Changes

JumpCloud has implemented updated automatic actions for devices running older versions of macOS, which will allow admins to target older versions of macOS to upgrade automatically to macOS 15 Sequoia.

  9. (Optional) Select the Policy Groups tab and select one or more policy groups that will include this policy.
