Sometimes an incompatible or damaged Audio Units plug-in manufactured by a company other than Apple can cause issues in Logic Pro X or MainStage. If you can open Logic Pro or MainStage, you can try disabling plug-ins to troubleshoot your issue. If you can't open Logic Pro or MainStage, you can try removing plug-ins.

Disable Audio Units plug-ins

If you're having an issue in a particular Logic Pro project or MainStage concert, note the third-party plug-ins you're using in the affected project. Then, try disabling the plug-ins one-by-one using the Plug-In Manager, testing the project after disabling each plug-in.

  1. Open Logic Pro or MainStage. In MainStage, you must open a concert to access the Plug-In Manager.  In Logic Pro, make sure to turn on Show Advanced Tools.
  2. Choose Logic Pro X > Preferences > Plug-In Manager, or MainStage 3 > Plug-In Manager.
  3. In the plug-in Manager, locate the plug-in you want to disable, then deselect the checkbox in the Use column. You can filter by manufacturer by clicking the manufacturer's name in the left column.
  4. For the changes to take effect, quit and reopen Logic Pro or MainStage. 
  5. Test the project or concert. If the issue no longer occurs, you can try reinstalling the disabled plug-in, or checking with the manufacturer for an update.

Remove Audio Units plug-ins

If you can’t open Logic Pro or MainStage, try manually removing plug-ins. Most plug-ins install to this folder:

  • /Library/Audio/Plug-Ins/Components

Other plug-ins install to this folder:

  • ~/Library/Audio/Plug-Ins/Components. To access this folder, in the Finder press Option, choose Go > Library, then navigate to the Components folder.

If you suspect a particular plug-in, locate the file for the plug-in, move it to a new location on your computer such as your Desktop, then try opening the application.
