✅ 1. Create the .mobileconfig file

Save the following content into a file named ChromePolicy_user.mobileconfig:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"
 "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>PayloadContent</key>
  <array>
    <dict>
      <key>PayloadType</key>
      <string>com.google.Chrome</string>
      <key>PayloadVersion</key>
      <integer>1</integer>
      <key>PayloadIdentifier</key>
      <string>com.example.chrome.extensionv2.user</string>
      <key>PayloadUUID</key>
      <string>11111111-aaaa-bbbb-cccc-111111111111</string>
      <key>PayloadEnabled</key>
      <true/>
      <key>PayloadDisplayName</key>
      <string>Chrome Extension Manifest V2 Block</string>
      <key>ExtensionManifestV2Availability</key>
      <integer>2</integer>
    </dict>
  </array>
  <key>PayloadType</key>
  <string>Configuration</string>
  <key>PayloadVersion</key>
  <integer>1</integer>
  <key>PayloadIdentifier</key>
  <string>com.example.chrome.config.user</string>
  <key>PayloadUUID</key>
  <string>22222222-bbbb-cccc-dddd-222222222222</string>
  <key>PayloadDisplayName</key>
  <string>Chrome User Policy Config</string>
  <key>PayloadOrganization</key>
  <string>YourOrg</string>
  <key>PayloadDescription</key>
  <string>Force Chrome to block Manifest V2 extensions</string>
  <key>PayloadScope</key>
  <string>User</string>
</dict>
</plist>

🛠️ 2. Install the profile

Note: profiles install is deprecated in macOS Ventura and above.

• Open Finder and double-click the ChromePolicy_user.mobileconfig file
• macOS will open System Settings → Profiles
• Click Install

This will apply the policy only to the current user, not system-wide.

🔍 3. Verify in Chrome

• Open Chrome
• Go to: chrome://policy
• Click “Reload policies”
• You should see:

"ExtensionManifestV2Availability": {
  "level": "mandatory",
  "scope": "user",
  "source": "platform",
  "value": 2
}

❌ 4. To uninstall the profile

Terminal:

profiles remove -identifier com.example.chrome.config.user
