How to Fix No New Software Bug in macOS Tahoe 26.2

Is your Mac stuck on an old version of Tahoe or Sequoia and claiming there are "No updates available"?

Recommended Troubleshooting Tool

Before proceeding with manual fixes, we recommend using CleanMyMac X. Quickly identify high CPU apps and optimize system memory with one click.

The Symptom

You know a new point release is out, but System Settings > Software Update says "Your Mac is up to date."

The Fix

1. 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.

1. Clear the Software Update Catalog

Reset the catalog URL to the default Apple production branch:

sudo softwareupdate --clear-catalog

1. 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.
