So I moved all the AU plugs to another folder, and was able to open the Plugin Manager, which let me disable the failed ones.
Over half of them passed the check when scanned individually.
However, some AU's, like Line 6 Helix Native, didn't even get scanned.
Is there a way I can manually scan them, if they are in the 'Components' folder, but don't appear in the Plugin Manager?
Thanks.
