While our developers are working with Apple to find a solution as fast as possible, the following workaround will allow you to open your NI plug-ins in Logic as normal:

  1. Navigate to  Logic Pro > Settings (or Preferences) > MIDI

  2. Uncheck the box MIDI 2.0.

That's it. You will now be able to load your NI plug-ins in Logic.
