Once that is all set up, you set a column (such as tags) that you want to make collections from. You load some books onto the paperwhite from Calibre. You select Create Collections on the Kindle from Calibre.
Then you eject, unplug, and go to Collections Manager, start it up. Then go to settings and select "Import collections from Calibre." It can take a few minutes.
You have to do that each time you add books via Calibre (if you want them to go into a collection), if you don't, your changes will not appear.
Brilliant! It worked (it works the same way on the Mac as in Windows, just as you described. It just took me a while to work out that I didn't need to use the command line interface to install NiLuJe's plugin).
