“Kindle for Mac 1.23 no longer runs at all on MacOS 10.15 Catalina. How can I remove Kindle DRM on Mac?”—This is the comment from one of our customers. This comment also arises our concentration. After doing some research, I find many reports about this Mac new system “Catalina is the first version of macOS to exclusively support 64-bit applications. MacOS 10.15 Catalina is currently in beta and will be released in fall 2019.” How will the new MacOS influence us? Since this new MacOS only supports 64 bits application, kindle for Mac 1.23 is 32 bits and obviously it will not work on MacOS 10.15 Catalina. Meanwhile, downgrading Kindle for Mac to older version is not a valid method to remove Kindle DRM any more on the MacOS 10.15 Catalina. Is there any solution to remove the Kindle DRM on MacOS 10.15? Sure. Here I will introduce 3 effective methods to remove Kindle DRM on MacOS 10.15. They are 100% working.
