Library location?

Hmm, that's a bit odd. You seem to have found the MC Library directory, but it's not in the right place. JMD files are MC library files. That cache directory and the contents you list are in my MC Library directory.
The words are very confusing here. Let me explain:
1. On a Mac, the Library directory, which is located in each user's home directory, is a place to store "special" files. Mostly files that are used by Apps. But also stuff that Mac OS uses. Preferences and that kind of thing.
2. There's also a Library directory on almost every Mac at /Library , which is NOT in any users' home directory. This is kind of a "master" or "default" Library directory.
3. As if that's not confusing enough, MC calls it's database a "Library". On Mac, JRiver has chosen to put this MC specific database (which it calls a Library) in a subdirectory of the user's Library directory: <userdir>/Library/Application Support/J River/Media Center 25/Library/
That last one, the JRiver Library (database) is where the JMD files are. These hold all the metadata about your default MC collection.
However, as you have pointed out, you can create more than one MC Library. Your proposed "sandbox" library is a good example. You can put the database files (JMDs) for this Library in any EMPTY directory that you want. I have chosen to put my MC Libraries into:
<user dir>/Documents/JRiver/Libraries/<library directory name goes here>
In your case the library directory name would probably be "sandbox" and you would create it fresh, with nothing it in, just before telling MC that you wanted a new library there. MC would then create fresh JMD files and dump them in there to hold your Sandbox library.
This topic, as I have mentioned, gets a bit confusing. The overlapping words don't make it any easier. I hope I have helped to clear this up, but I would understand if you have more questions now.
Good luck.
Brian.

Thanks again. I'll have to read through your post a couple of times to be sure I understand it.
I've found some of what you describe:
Macintosh HD/Library/…
Macintosh HD/Users/[username]/Library/Application Support/J River/Media Center 25/Library there are .jmd files here
What I don't find is this:
Macintosh HD/Users/[username]/Library what I find instead is:
Macintosh HD/Users/[username]/MC Library/Application Support/JRiver/ there are subfolders here for MC 21 and MC24, must be relics.
I wanted to keep my library folders in the same general location, so now I know the path, I can create:
.../Library/Application Support/J River/Media Center 25/Library/Sandbox and have MC25 put all the sandbox .jmd files there.
macdonjh:
Worked like a charm, almost.
When I created my new MC Library, Sandbox, and opened it, MC told me the file would be opened in Read Only and changes will be lost upon exit. True to its word, MC showed me an empty Library when I closed then reopened Sandbox. Is that because I have it as a subfolder to my main library?
Other than that, the experiment worked well. Thank you for your help.

As I mentioned before, <userdir>/Library is HIDDEN. You must enable access to it, or directly go to it using Finder's Go > Go To Folder menu item.
The path "<userdir>/MC Library/" is not standard. I suspect you created this somehow, but I can't be sure. I know it's not on my Macs and I've had MC for Mac since version 20.

This is a very bad idea. You need to create new MC Libraries in empty directories. If you try to put one library in a subdirectory of another library, you are effectively mixing them together a bit. Because each MC Library folder has it's own subdirectories.
You might want to establish a new master location for all of your libraries. You would create new libraries there and move your existing library there also. That's how my main MC for Mac machine works: I cloned the main library into a new folder in my new master location for all libraries:
<userdir>/Documents/JRiver/Libraries/Main
Then other subdirectories like:
<userdir>/Documents/JRiver/Libraries/Joes Library/
<userdir>/Documents/JRiver/Libraries/Video Test/
etc.
Each one has their own outer folder so they are not mixed or overlapping.
You can leave your main library right where it is if you want, and just create your sandbox library in a different location. That's less work, though it will not consolidate them all under one directory tree.

I used Go > Go To Folder menu item to get to the Library folder.

I have no idea how this folder got on my machine. I don't remember creating it on purpose. I guess I will leave it alone for now.

I didn't put my new SANDBOX library in the same folder as my MC-created main library. See below:

<userdir>/Documents/JRiver/Libraries/Video Test/
I did this. My MC-created Main Library is in folder /JRiver//Media Center 25/Library
My SANDBOX library is in folder /JRiver/Media Center 25/Library/ Sandbox
Each one has their own outer folder so they are not mixed or overlapping.
