Did you have a working DeDRM setup on this machine previously?

[ZolaLa9]

See this post: https://www.mobileread.com/forums/showpost.php?p=3819708&postcount=508

If you had a working DeDRM setup before you upgraded to Catalina, you may be able to get it working by copying over backups of the following files/folders:

• User > Library > Application Support > Kindle folder
• User > Library > Preferences > com.apprenticealf.dedrm > KindleKey.der
• User > Library > Preferences > calibre > plugins > dedrm.json

[edwardoblenis]

Thank you for helping.

No, there was no DeDRM setup on this machine previously. This is the first time that I have reopened Calibre in a number of years.

[ElleKayEm]

ZolaLa9 is much more familiar with the Mac side of things than I am. But I don't believe there's a way at present to start from scratch on Catalina.

[ZolaLa9]

Unfortunately, ElleKayEm is correct. The only way I'm aware of to get Kindle for Mac and DeDRM to work together on Catalina is to have a previous working setup.

Ideally it should be on the same Mac, but if you have a backup from another Mac, you could give it a try.

[edwardoblenis]

Thank you for clarifying. Wow! That's kind of horrible news. So if I want a PDF version of a book and use Catalina the book can't be a Kindle version? Correct? Is there a workaround? Like, would it make more sense to download from a different seller?

[ElleKayEm]

There are potential pitfalls with other ebookstores as well. Barnes & Noble Nook is much more trouble than it's worth for anyone now. The other major DRM these tools work on is Adobe DRM, and the most reliable program for getting books whose DRM can be removed is a 32-bit program (Adobe Digital Editions 2.0.1).

If you have an E-ink Kindle (that is, not a Fire), you can download a copy of the book from the website which can be DeDRMed. There are a few books which are not available that way however.

[ZolaLa9]

If you have an e-ink Kindle, you can use Method 3 here: https://www.mobileread.com/forums/showthread.php?s=ee1c821250e0fe203d396e7a0fa548b0&t=283371 Some people have purchased cheap used Kindles just for this purpose.

You could also try a vendor that uses Adobe Digital Editions (ADE), but you will need to use ADE 4.x as earlier versions won't run on Catalina, and ADE 4.x is capable of hardened DRM that cannot be decrypted at this time. I'm not 100% sure, but I think ADE epubs from Kobo and Google Play still work.

Kobo also has a proprietary format (kepub) that is decrypted with the Obok plugin. I'm not sure if that works with Catalina.

You can also wait and hope someone will figure out the new Kindle decryption so that K4Mac will work with Catalina without a pre-existing setup.

Finally, you can set up a virtual machine on your Catalina Mac and install a Mojave VM or Windows VM then install Kindle for Mac/PC on the VM.

[edwardoblenis]

Much thanks to the both of you for outlining these options in such great detail. I’ll probably look into buying a cheap E ink Kindle (used to have one and probably tossed it) or wait for the next ingenious decryption creation. THANK YOU!

[ZolaLa9]

Any chance your old Kindle is still registered? If so, you don't need the actual device. As long as it's still registered, you can use Method 3. (You can get the serial number from your Amazon account under My Content & Devices.)

[edwardoblenis]

I just checked and I must have un-registered it. Thanks for the suggestion though.
