I have tried to take into account the KFX file layout used by the new Kindle for Mac and iOS apps. If I missed something it should be an easy fix to make gathering the proper files work.

Unfortunately without DRM removal no book in KFX format, other than a personal document, can be imported into calibre. There are two potential issues with new Kindle for Mac DRM.

The first is obtaining the key associated with the app installation. The old app used a .kinf file much like Kindle for PC. It has yet to be discovered how the new app stores its key. Possibly in the keychain.

The second issue is the new DRM algorithms implemented since the last DeDRM release. Amazon has been hard at work adding new DRM algorithms lately. The latest Kindle for PC is unusable because of that.
