If you see a message saying your App is damaged don't panic. 

This error is caused by the Mac App Store failing to verify the app as it opens.  The error is rare and has nothing to do with the application itself.

How do you fix it? Just uninstall the app, restart your computer and then just go download the app again from the Mac App store. You won't be charged again to download it again. Just make sure you're signed into the Mac App store with the same Apple ID you bought it with.

Shedworx Apps that might show this message:

  • Smart Converter Pro
  • Music Converter Pro

If you're having no luck with these suggestions, we have had reports that running the macOS TV or Music apps at the same time as a Shedworx app can cause the 'app is damaged' message to be displayed.  As a last resort try quitting the macOS TV and Music apps and restarting the required Shedworx app.

If you have no luck with these suggestions, we can always give you an Activation Key for the Shedworx version of the app that you bought from the Mac App Store.  The Shedworx versions are a direct download from us and don't rely on the Mac App Store in any way.
