Re-scanning AU plug-ins in Logic and Garageband

If you're using Logic Pro, most problems can be solved by re-scanning the plug-ins from within Logic.

1. Go to the main Logic Pro menu and select Preferences/Plug-In Manager
2. Scroll down the left-hand list and select the Sonnox Manufacturer
   • Unavailable plug-ins should be easy to spot, since their Use tick box will be un-ticked
3. Select the unavailable plug-ins and click Reset & Rescan Selection at the bottom of the window

If your iLok account and licences are set up correctly, the plug-ins should pass the AU validation scan and become available to use. If they don't pass, please read Why doesn't my plug-in show up in my DAW?

If your plugin still doesn't show up,  Simply press 'Full Audio Unit Reset' and restart Logic or Garageband

If you are using an older version of Logic, please read on to reset your AU cache manually -
