I have uploaded several ebooks (Mobi format, not bought via Amazon) onto my Kindle personal library, and I can read them without a hitch on my Kindle device, but not on the Kindle app for Mac. Is this a restriction placed by Amazon or a configuration problem? Is there a workaround? All I want is to synchronyze all of my ebook reading on Kindle, Mac and Ipad.


You certainly cannot synchronize them with Amazon software, because they allow onto their cloud only their products.

You can do it however with a very nice application, Calibre, which exists for Mac as well as for Linux and Windows.

If you want, you can get around the DRM (Digital Rights management) restrictions by means of a smart app, which you can download here. This will allow you to synchronize all your e-books across different reading platforms, by using your Mac as the synchronizing agent.

  • Thank you for your answer, but I have been using Caliber, and that is not really the issue. The problem is that, while my entire ebook library (Amazon-bought or not) is available on the Kindle device, the CALIBER-CONVERTED EBOOKS (.mobi) are NOT READABLE OR SYNCHRONIZABLE on the KINDLE FOR MAC app. All the ebooks I converted on Caliber and uploaded to the Amazon library are DRM-free, by the way.

  • @Joe Thanks for point out what I have missed. Just for the sake of curiosity: can you read all books with Calibre? If so, why do you need the Amazon app for Mac? May 20 '14 at 14:38
  • Because I don't want to do all of my ebook reading exclusively on the Mac, but would prefer to synchronize my reading progress on Kindle, Ipad and Mac. It's a really nice Kindle feature that I would like to have for my entire library, if I can: that way I can stop reading on one device and pick up at the same point on a different device later.

  • @Joe Though I never use this feature, it does make sense. However, Amazon cloud simply does not allow me to upload, and thus synchronize stuff which I did not directly buy from them, not even pdf files. May 20 '14 at 14:48
