I had Kindle for Mac v1.5 and it wasn't syncing, retrieving my Archive items, or allowing me to re-register. I upgraded to the latest version (v1.6) and it was still no go. I deleted the app and also what was under /Library/Application Support/Kindle and re-installed from the App Store. From that app you'll be able to properly tag, manage, and send ebooks to your Kindle devices. This works with a similar method to the above, but you just have to add the Calibre app‘s email.
