@lilshim: There is no plugin, but what you can do to get the sync working between Mac and other devices (Kindle, smartphone, tablet) is this:

-download your PDOC on you Kindle from the Cloud arcive.
- Connect your Kindle via USB cable to you Mac (or PC)
- copy the book file (azw, mobi, prc...) from "documents" folder on Kindle drive to "My Kindle Content" (or whatever is the name of the folder where "Kindle for Mac" stores downloaded books, on Windows & "Kindle for PC" app the books are stored in "Documents/My Kindle Content" folder) on your computer. If the books download with filenames containing random string of characters instead of book titles you can just sort the folder by modification date and that way find the most recent download.


That's it, the sync should now work. PC and Mac Kindle app don't display archived PDOCs but once you have correct file (= the same file, or to be more precise files containing the same ASIN value) copied to correct location the syncing works just like it works for books from Kindle Store. You're just not able to download PDOCs directly within Kindle for Mac/Kindle for PC app.

"Kindle for PC" will not display book cover thumbnail (there is not even a title on generic cover, it displays just white thumbnail with "PDF" flag on it ) for books transferred manually so you must switch to list view to be able to sea book titles and choose the correct one.
