For Kindle books owners, do not update Kindle for Mac to version 1.32 or higher if you need to remove DRM from your Kindle files. As you know, right now the only way to remove Kindle DRM is to disable KFX format by using the command line. And the principle of running the command line is to prevent the renderer-test program from executing, blocking the use of KFX. However, version 1.32 Kindle for Mac does not come with the renderer test file. Therefore, the command line will not work if version 1.32 or later Kindle for Mac is installed.

So in order to remove Kindle DRM, you need to perform the following steps (BTW, it is the only solution to get rid of Kindle DRM so far):

Step 1Install the latest Epubor Ultimate on your Mac.

Epubor Ultimate is an all-in-one eBook DRM Removal that help you remove Kindle DRM effortlessly. Besides, it can also convert your files to epub/pdf/mobi/azw3/txt with one click.

Step 2Make sure you are not using the latest Kindle for Mac.

Launch Epubor Ultimate, read the yellow reminder on the upper left corner of the software.

click the link to auto downgrade the kindle app

If it says that you are using the latest Kindle app, then you need to click the auto-downgrade link and click the Start button in the pop-up window to downgrade the Kindle app to version 1.31 automatically.

You must replace the other Kindle app while installing version 1.31 Kindle for Mac. Or you will not be able to remove Kindle DRM.

NoticeClick Skip this version when the new update reminder window pops up.

If the Kindle app version is 1.31 or lower, you can jump to step 3.

TipsYou can stop the Kindle app from updating to the latest version by unchecking box "Automatically install updates when they are available without asking me" after installing version 1.31 Kindle for Mac.

uncheck auto updates

Step 3Open the terminal window and run the command line.

Note: do not run the Kindle for Mac before running the command line. Or it will cause you unable to remove Kindle DRM.

An easy way for you to open the terminal window is by clicking the magnify glass on the upper right corner of the screen, then type Terminal and hit the enter key. The terminal window will pop up immediately. Next, copy and paste this command line to the terminal window and hit the enter key: sudo chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test. Last but not the least, you are required to input your power-on password and hit the enter key again to run the command line successfully. And below screenshot is what you’ll get after successfully running the command line.

TipsIf your Mac has no power-on password, you should enter this command line instead: chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test.

TipsDo not download Kindle books by double-clicking the book cover and remember not to open the book after successfully downloading, or it will cause you unable to remove Kindle DRM.

I have repeatedly tried to get epubor to remove the arm from a kindle book but cannot get it to work. I have followed the instructions and reverted to 1.31 but still no luck.



01/25/2022 12:27:27
Do I have to pay to get more than 20% of the book wtf?
07/6/2022 18:32:02
Thanks, this works, but REMEMBER TO DO THE COMMAND LINE BEFORE OPENING KINDLE after kindle has been downgraded to the older version. Then, as it says, after entering the command line and your password, you can open kindle (and disable auto update!), download your books, go back to Epuber and click the kindle button to refresh downloaded books.

Bonjour, Votre réponse me parait intéressante. J'ai effectué la ligne de commande après avoir installé Kindle 1.31. Mais je n'obtiens pas le même résultat que dans l'article. Est-ce normal ? La réponse que j'ai c'est à chaque fois : No such file or directory.Est-ce que vous auriez des conseils à me donner pour débloquer mon problème ?

i have entered sudo chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test. but after i have entered the password. it turns out "chmod: /Applications/Kindle.app/Contents/MacOS/renderer-test.: No such file or directory".

Trying the trial version before I drop money on a program that may not work. I have kindle for Mac 1.31 and have tried instructions as indicated. No luck with removing kfx drm. Also tried removing it straight from Kindle Paperwhite plug into my MAC, no luck. Amazon no longer allows transfer via USB. Suggestions?
01/31/2023 09:10:08
"Download and transfer via usb" doesn;t work for kindle unlimited books and textbooks.
If your purchased books are not that kind of books, you still can download via "Download and transfer via usb".
Now please screenshot your error message and send them to us via support@epubor.com.

Kindle for Mac is up to 1.39.  1.31 can no longer download some books (oddly, older ones). Ideas?
01/31/2023 09:11:10

We arware of this issue. It seems the amazon kindle has changed something in the new published kindle books. It requires the latest kindle app to download it. For the books published before 2023, it still can be downloaded with old kindle app and can be decrypted with Epubor Ultimate.

Now we are working on this issue. Once there is a solution, we will let you know. The older kindle books still can be cracked with Epubor Software.

For the ebooks published in 202, here is still another way to remove drm from this kind of kindle books if you have any kindle eink device registered with your amazon account. Please download the kindle books via "Download and transfer via usb" and then remove kindle drm with Epubor Ultimate. Here is the detailed guide: https://www.epubor.com/how-to-remove-drm-from-kindle-kfx-ebooks.html#meth4

The suggested solution helped for 2 of 3 books.

The third one appears to have DRM. I tried plugging in my Kindle and there is no difference in operation. I looked up the serial number and attempted to enter it. The screen has a "click to see how to find your serial number" (paraphrased) but no way to enter the S/N.

02/13/2023 11:02:54
Thank you for your message. To enter the kindle serial number, please launch Epubor Ultimate, click the person icon at the top right corner>>setting>>kindle>>then fill in the kindle serial number at the right side and click “Ok" button.
02/13/2023 23:34:33
Still can't find where to enter the serial number. I can send you a screenshot showing the lack of button/link.
02/28/2023 16:43:40
Thank you for asking. please refer the guide in this article to know where to input the kindle serial number: https://www.epubor.com/how-to-remove-drm-from-kindle-kfx-ebooks.html#meth4
02/8/2023 03:52:32
Now Amazon requires you to be on the newest kindle app ver to even download the books :( So I cannot even grab them to use your program.
Is there a fix for that?
02/13/2023 12:07:51
