No /Application Support/audacity folder for 2.1.3

I downloaded 2.1.3 and I’m trying to add a Nyquist effect plug-in to the program, but I don’t have an application folder in “Application Support.” How should I install the plug-in? Or should I still have the folder in my library? Thank you!

Mac has hidden Home/Library ever since Lion.

Open Finder, use the “Go” menu at the top, choose “Go to Folder” and type or paste:

~/Library/Application Support/audacity/

Now you will see the “Plug-Ins” folder.
