The problem that I have is that I downloaded the Thomas Mundt Loud Max Plug In BUT the thing is I think I messed up with something when I had my computer (I-mac High Sierra 10.13.6) a while back by somehow deleting the Library itself and replace it by my own files. So now the problem that I have is that Audacity cannot find the plug-in because it normally sources it from the Library which is not there anymore. I tried to change the place from where Audacity sources new plug-ins with no success so I’m in a ‘‘Cul-de-Sac’’ and as a pure computer dummy I am out of solutions for the moment. 
Can someone help me out with this? 
Has the “Thomas Mundt Loud Max Plug” ever worked with Audacity? (do you know for sure that it is compatible with Audacity?)
It works in Audacity on Windows …
There are 32-bit & 64-bit versions, only 32-bit plugins will work in Audacity.
[ IMO Audacity’s native limiter, (with make-up gain enabled), can do a better job than LoudMax]
Thanks for replying… Yes it works and I saw how they do it online but as I mentioned, I messed up and don’t have a Library no more in my computer and Audacity normally sources new plug-ins from the Library so the consequence is that Audacity doesn’t ‘‘see’’ the new plug-in. I tried to look for a way to change the settings in Audacity to source the new plug-ins from a different place in the computer but I still haven’t found that Setting Option yet…
You must have a Library folder under your user account. I don’t understand how macOS could operate without it.
In the Finder, click on the “Go” menu and choose “Go to folder”. In that dialog, type ~/Library. Inside the Library folder there should be the “Application Support” folder, and inside that, the “audacity” folder.
Does that work?

Hi Bill, thank you for replying. I tried what you told me to do and part of it works… I have access to the Library but when I put the vst and\or the au version of Thomas Mundt Loudmax where it is supposed to go Audacity still doesn’t ‘‘see’’ it so I still don’t have access to it. I tried to put it where I was told @ the beginning which is: Audio\Plugins\VST and then tried to transfer it @: Application Support\Audacity\Plugins but still getting the same result yet…
Maybe it’s because the only way I can access the Library is by the way you told me, maybe it’s just not @ the ‘‘right place’’… what do you think Bill?
Put it in ~/Library/Application Support/audacity/Plug-Ins/.
An easier way to access your Library folder is this: hold down the option key while clicking on the Go menu.

I already put the VST in this file. I don’t have a hard time access the file, the problem is that even if the VST is in there in the correct file Audacity still doesn’t ‘‘see’’ it. When I open Audacity, open the audio file I want to modify and when I go in Effect, the Thomas Mundt Loudmax plugin is still not in the listing
After you put the file in the correct folder, you need to do Effect > Add / Remove Plug-Ins, then enable the plug-in.
