Description

With very little effort devices may be upgraded to macOS Monterey using the provided recipe.

Info
titleUpgrading older versions

Devices running earlier versions (pre 10.8 Mountain Lion) will require updating twice; Apple recommends upgrading to El Capitan and then to Monterey.

Apple's full list of macOS Monterey Compatible Devices

Note

This process is designed to upgrade devices.  If it is desired to wipe devices and then install a version of macOS, please take a look at the example recipe: Wipe and Install macOS 10.13.4+ (Intel)

Info
titleDisk Space Requirements

macOS Monterey requires 26 GB of free disk space to install.  The installer is ~12 GB so a total of 38GB of free disk space is required for this Fileset to execute properly.

titleFull installer

Confirm the installer app is the complete installation (8+ GB) before continuing. If the app is less than 50MB, re-download the Install macOS Monterey.app. A full installer may be downloaded through Terminal on macOS 10.15+ devices. Example to download the 12.0 full installer to the Applications directory:

Code Block
languagebash
titleDownload Full Installer
softwareupdate --fetch-full-installer --full-installer-version 12.0

Typically Apple only provides the latest point release of each Major OS version: 10.13.6, 10.14.6, etc.  For a full list of available updates, use the following command:

Code Block
languagebash
titleList Full Installers
softwareupdate --list-full-installers
Tip

Associate Fileset as a Kiosk association for the end-users to install in their own time.

Tip

titleRe-running the Filesest

This Fileset adds a file to prevent re-running the installer. If the installer requires re-running, this file will need to be removed in advance:

Code Block
languagepowershell
rm -rf /var/db/.upgrade-to-monterey-fw-installed
  1. Download and import the attached Fileset recipe: Upgrade macOS 12 Fileset

  2. Once imported into FileWave, open the Fileset to view the contents window; ensuring 'Hide unused folders' is selected
  3. In the Applications folder add the downloaded 'Install macOS Monterey.app'; the .placeholder may be removed

    Image Removed

  4. Use Get Info > Verification to set the entire 'Instal macOS Monterey.app as 'Ignore at Verify (Left Behind)'
  5. Edit the Environment Variables as appropriate (see below)
  6. Associate to test machines
  7. Once tested, deploy to appropriate clients

Environment Variables

The Environment Variables must be edited, adding the FileWave Server Name as the Value for the Variable: 'server_name'.

In doing so, some other variables will also be shown, which may require updating.
