Logic Pro X Use the Plug-in Manager
Logic Pro uses a validation tool to ensure that only plug-ins that fully comply with the Audio Unit plug-in specification are used in Logic Pro. This minimizes problems that may be caused by third-party plug-ins. The validation process takes place automatically when Logic Pro is first opened, when an updated version of Logic Pro is installed, and when you install new plug-ins or update existing ones.
In the left column of the Plug-in Manager window, all internal Logic Pro plug-ins are sorted by Category, and all installed Audio Unit plug-ins are sorted by Manufacturer. The results of the validation scan are shown in the Compatibility column at the right of the window.
You can organize and manage plug-ins by simply dragging within the Plug-in Manager window. You can also create new plug-in categories and rename or remove existing ones as well as search for individual plug-ins by name.
The Plug-in Manager is only available when Show Advanced Tools is selected in the Advanced preferences pane.
Open the Plug-in Manager
Choose Logic Pro > Preferences > Plug-in Manager.
Create a new category
Click the Plus button (+) to the right of the Category column header.
Enter a new name for the Untitled folder that appears, then press Return.
Rename an existing category
Double-click the folder, enter a new name, then press Return.
Remove an existing category or plug-in
Do one of the following:
Select the category or plug-in, then press the Delete key.

Any plug-ins that match your search term are displayed in the results list.
Manually enable plug-ins that fail the validation test
Select Show All in the upper-left part of the Plug-in Manager window.
Select the plug-in’s checkbox in the Use column to enable it.
You should be aware that these plug-ins can cause problems. If you encounter problems with manually-enabled failed plug-ins, click the Disable Failed Audio Units button.

The plug-ins will be activated automatically, if they pass the validation scan.
