The Symptom
You know a new point release is out, but System Settings > Software Update says "Your Mac is up to date."
The Fix
- Force a Refresh via Terminal
The GUI often relies on a stale cache. Force a manual check:
softwareupdate -l
If it finds the update, install it directly: softwareupdate -i -a.
- Clear the Software Update Catalog
Reset the catalog URL to the default Apple production branch:
sudo softwareupdate --clear-catalog
- Delete the Update Preference Cache
Run:
sudo rm /Library/Preferences/com.apple.SoftwareUpdate.plist
sudo killall com.apple.MobileSoftwareUpdate.Service
Pro Tip
If you were ever in the Beta program, go to Software Update > Beta Updates and ensure it is set to "Off" to see the latest stable public release.
