This tutorial teaches you a simple way how to convert your epub or html books using Amazon Kindlegen tool to Mobi / Azw native Kindle format. There are some drawbacks to that Approach: There is too much Hassle opening the terminal, dragging the Kindlegen to the Terminal every time, then dragging the book file to the Terminal, pressing the enter key in the Terminal. Why not doing the conversion just in Finder through the Contextual Menu "Open"/"Open With" menu, or dragging it to an app on a Dock or on the Desktop? You may want to try the Kindlegen helper app on Mac OS X called Candelabrum, to try it out please visit http://candelabrum.net.
