after running the sudo command, downloading and convertig kindle books to pdf-files, I can no longer use the kindle app to read books/ display book contents. The kindle app crashes. Even reverting the chmod command (sudo chmod +x …) does not help. Any advice?
Then you need to redownload your kindle books again.

Hello, I just finished using your software on my mac with kindle version 1.30 and Big Sur OS. It definitely works and I am very happy with it. If I could make a few suggestions that I think will help you and other buyers. It wasn't working at first and then in one of your explanations I saw where you said to make sure Kindle was off while I convert my files. I had not remembered reading that in any of the other write ups and that's what it took to work. Second...after converting the files, my kindle would crash. I remembered seeing the terminal command in one of the reader comment sections to reverse what I had performed prior but it took me a while to find it. I would suggest that everywhere you put the thermal line to change Kindle, you would include the terminal line to change it back the way it was. Lastly, you have done a tremendous amount of work on this product and depending on what your source is and what you are converting it to, it can be somewhat overwhelming which directions to follow. For a bit, I even tried to go back to kindle version 1.23 but then realized that that was a 32bit software and those instructions wouldn't work for me. If you had a page that had a decision tree or algorithm where at the top you start with your source material identification after a few other pertinent questions that guide you different directions down the algorithm, end with your destination choice and there would be a link to directions specific to your situation that would be fantastic. I really liked the video you put in the KFK section to confirm my steps were correct.
Again...love the software and will be a great resource to have from now on.
Steven
Look forward to your early reply.
Thank you so much for this! It worked perfectly for months, but I tried opening my Kindle app this morning to download some books and it will no longer open on my Mac (OS 10.15.7). I opened Terminal and entered the command again in case it had somehow gotten erased (can that even happen???) but it still won't open.
Any advice?
Do you mean that your kindle for Mac cannot open anymore on Mac catalina? Please close the kindle app and you can reverse to it to the original by using the following command: sudo chmod +x /Applications/Kindle.app/Contents/MacOS/renderer-test.
Then try to open the kindle for mac again on your Mac platform.
Any more problem, please feel free to contact us via support@epubor.com
Ok so here is the guide for people that have Big Sur 11.1
1. Go to mac.filehorse[DOTCOM]/download-kindle-for-mac/
1.1 and select OLDER VERSIONS from the tab
1.2 download the 1.26.1 version of kindle
2. Then to stop the kindle from updating !
2.1 Amazon has gotten aggressive with forced auto-updates, even if you have unchecked auto-updates in
Preferences. To get around this, go to User > Library > Application Support > Kindle folder and
replace the "updates" folder with an empty txt file named "updates" (no extension)
OR
apply chmod -w to the "updates" folder. After you do that, K4Mac will ask if you want to download a
new version every time you launch the app, and you can choose no.
3. Folow the guide on this page:
3.1 - Remove all books
3.2 - Run the terminal command - sudo chmod -x /Applications/Kindle.app/Contents/MacOS/renderer-test
3.3 - Right click then download
3.4 - Run Epuber and convert the book
IT DOESN'T WORK AND IS A WASTE OF MONEY!!!!!!!!!
Thank you for using our software and sincerely sorry for this issue. That's because the kindle app 1.32 has changed something. To remove kindle drm, please install kindle for MAC 1.31 and then run the command to avoid the kindle kfx format.

i bought epubor today and spend all day trying to make it work with no success.
i am in the exact same situation as Marion (owner of Mcbook air) and followed the instructions to the letter, even download older version of kindle, looked at all your videos, tutos, FAQs and whatnot but when it comes to the input on the terminal, i have the same message "No such file or directory" which is blocking me once i want to convert my book.
You do have great reviews so please find us a solution or please make a commercial gesture and give us a refund.
Glad I checked the comments and found this - I think because I was jumping around these articles/tutorials and they're not all updated accordingly I did not think downgrading to Kindle 1.31 would work (another epubor article states that downgrading will not work on Big Sur).
Anyways, I was able to successfully downgrade within the epuborUltimate app (trial). The process was unbelievably easy and smooth for me. Command line worked properly after doing so but very important that the command is entered PRIOR TO opening Kindle 1.31 after downgrade.
Had some minor issues getting Ultimate to find my downloaded Kindle books (they were not automatically showing up in the list) but was able to resolve this by redirecting my Kindle downloads in the Kindle app to a folder I created on my desktop. Altered the Kindle Source Location to that same desktop folder in Ultimate. Tested two ebooks this way and seems to be working perfectly now.
Wanted to share in case anybody else is still having issues. I'll be purchasing the full version now.
How can you sell a product that does NOT work??!!!

I NEVER GOT MY REFUND! AND IT STILL DOESN'T WORK!!!
I am using Mac version Kindle 1.31 as suggested. I typed in the command in terminal exactly as stated. The file that downloads IS a .azw. I still get "failed" when dragging and dropping the file into Epubor Ultimate.
I don't understand why you want to scam people by selling a product that does not work. Only to collect people's money and never offer support, no replying to emails, and refuse to give refunds.
Yes, please screenshot and send it to us via support@epubor.com. Then we will try our best to help you. Also, you can try to fix your problem by following this instructions at first: https://www.epubor.com/updating-kindle-for-mac-to-132-or-higher-will-prevent-you-from-removing-kindle-drm.html
