Managing Safari Extensions in macOS Sequoia

Safari extensions can be managed via declarative device management (not a profile). Documentation for the new configuration will appear here: https://developer.apple.com/documentation/devicemanagement/safariextensionsettings.

The schema for the new configuration is here: [broken link removed; see below for the right one].

Thanks @Engineer for the speedy reply. The yaml file you added is not public but I see the documentation and I understand that my MDM provider will need to support this so I'll take this with them. Thank you.

Sorry, here is the correct public schema link:

Hey, Im trying to test this on a mac with seqouia OS installed. I generate profile and load it manually, but it doesn't seems to work. The profile I loading is the following:

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>PayloadType</key>
    <string>Configuration</string>
    <key>PayloadVersion</key>
    <integer>1</integer>
    <key>PayloadIdentifier</key>
    <string>com.test.safari.config</string>
    <key>PayloadUUID</key>
    <string>E60B9C54-4FF1-4A72-9D44-2B6A1CC4E73E</string>
    <key>PayloadDisplayName</key>
    <string>Safari configuration</string>
    <key>PayloadContent</key>
    <array>
      <dict>
        <key>PayloadType</key>
        <string>com.apple.configuration.safari.extensions.settings</string>
        <key>PayloadVersion</key>
        <integer>1</integer>
        <key>PayloadIdentifier</key>
        <string>com.test.safari.config</string>
        <key>PayloadUUID</key>
        <string>E60B9C54-4FF1-4A72-9D44-2B6A1CC4E73E</string>
        <key>ManagedExtensions</key>
        <dict>
          <key>com.grammarly.safari.extension.ext2 (W8F64X92K3)</key>
          <dict>
            <key>State</key>
            <string>AlwaysOn</string>
            <key>PrivateBrowsing</key>
            <string>AlwaysOn</string>
            <key>AllowedDomains</key>
            <array>
              <string>*://*/*</string>
            </array>
          </dict>
        </dict>
      </dict>
    </array>
  </dict>
</plist>

But it doesn't seems to do anything. What am I missing? Can I test it this way or I have to go through MDM? Thank you.

For the record, Apple's support web pages are also broken when it comes to Safari Extensions.

1. Go to https://support.apple.com/en-gb/guide/deployment/welcome/web
2. Type Safari Extensions in the search field and run the search.
3. Click the link 'Safari extensions management declarative configuration for Apple devices'.

=> You're back to the Apple Platform Deployment home page.
