How to Hide the Red Software Update Badge on macOS Sequoia

For users running macOS Sequoia via OpenCore Legacy Patcher who wish to remain on their current stable version, the persistent red notification badge on the System Settings icon can be visually annoying. This badge is controlled by legacy system configuration files and can be disabled using standard profile commands.

1. Prerequisites

  • Target OS: macOS Sequoia (15.x).
  • Required Tools: macOS Terminal.

2. Compatibility Snapshot

  • Supported models: All Macs running macOS Sequoia.

3. Installation Preparation

  1. Close System Settings: Force close the System Settings application before running the commands.

4. EFI and config.plist Review

  1. This does not apply to this case because configuration is handled directly in macOS user settings and profiles, rather than OpenCore config files.

5. Post-Installation

  1. Disable updates via plist: Open Terminal and execute: defaults write com.apple.systempreferences AttentionPrefBundleIDs '{ "com.apple.preferences.softwareupdate" = 0; }'
  2. Restart Dock: Apply the changes by running killall Dock and killall SystemUIServer in Terminal.

6. Troubleshooting

Reported Issue: Software update badge remains visible
  1. Reset profiles: If the badge persists, you can use the profile configuration utility: sudo profiles -R -p com.apple.applicationaccess

7. Dual Boot and Advanced Configuration

  • This does not apply to this case because it only affects the macOS desktop UI preferences.

8. Verification, Maintenance and Rollback

  • Verification: Verify that the red badge on the System Settings dock icon has disappeared.
  • Rollback: To restore update notifications, run defaults delete com.apple.systempreferences AttentionPrefBundleIDs.

9. References and Glossary

  • defaults: A command-line utility used to edit macOS user preferences files.

Original Question: "I just want to stay on sequoia, Stopping the red update flag for update, visually annoying"

A while back a someone posted a script that changed via com.apple.applicationaccess to stop the red flag from appearing, and it worked wonderful. Unfortunately after my update to 15.7.7 I guess that setting got over written.

I was wondering if anyone saw, and remembers/save that post. I though I had, but I've been though the saved, searched my machine, looked everywhere. Anybody remember or got a clue, sorry for being old and forgetful....
