“Can’t Update” Error

If NetNewsWire’s auto-updater gives you an error that it can’t be updated, do this:

• Cancel the update if you still need to
• Quit NetNewsWire
• Move NetNewsWire to your Applications folder (or to your ~/Applications/ folder)
• Launch NetNewsWire
• Check for Updates again

That should do the trick!

The problem

If you’re running the app from your ~/Downloads folder, then the system has placed your app under quarantine — which means the app can’t update itself.

Once you move the app to another folder, the quarantine is lifted, and the app can update itself.

This does require your manual intervention: it‘s not something NetNewsWire can do for you automatically.
