AdditionalSongFolders= on Mac

So I've read the documentation on adding songs with AdditionalSongFolders=

However this isn't working or documented well on a Mac.

I have a secondary internal drive called Mediacenter X

In the Mac world, this would be called up in Terminal/command line like this /Volumes/Mediacenter\ X/

and then I have a few sub folders so the full path is /Volumes/Mediacenter\ X/StepMania/Songs/

...but that doesn't work.

What path is it expecting?

This is what I have

AdditionalSongFolders=/Volumes/Mediacenter\ X/StepMania/Songs/

Thank you!

it doesn't need the \, the list is not separated by spaces
