Where are third-party Audio Units plug-ins installed on Mac?
If you need to manually remove third-party Audio Units plug-ins, you can find the files in the Library folders on your Mac.
You can install Audio Units plug-ins from manufacturers other than Apple to process audio in Logic Pro X, GarageBand, and Final Cut Pro. When installed, Audio Units plug-ins appear as individual components in the Library folders on your Mac:
In the Finder choose Go > Go to Folder, enter "/Library/Audio/Plug-Ins/Components" into the Go to Folder field, then click Go.
You can also check the Library in your Home folder. In the Finder choose Go > Go to Folder, enter "~/Library/Audio/Plug-Ins/Components" into the Go to Folder field, then click Go.
Built-in effects and instruments included with Apple apps like Logic Pro X, GarageBand, MainStage, and Final Cut Pro X don't appear in the Library folders and can't be removed manually.
