Plugin folder locations
If you’re using Apple’s OS X, all your VST, VST3 and Audio Units go into pre-determined locations
So how does your DAW know where to look for your plugins? Actually, it might not. Mac users have it easy, as there are OS-specified folders into which plugins are installed. These folders can be found by going to your Library folder (if you can’t find it, go to the Finder’s Go menu, hold Alt, and a Library option should appear). Find the Audio directory, and then the Plug-Ins folder within. There you will find more folders still. One will be labelled Components – this is where your AU plugins reside. Other folders will be found alongside it for VST and VST3 plugins. If you’re a Pro Tools user, you’ll find your plugins in an Avid folder. If your installers don’t automatically install the plugins into the proper folder, you should manually copy them into the relevant folders listed above.
