Which makes me think that there is no issue with the adaptor as it would not be seen in finder. This paper describes the design and development of an AI-driven, interactive and user-aware virtual assistant aimed at helping users to focus their attention on reading or attending to other long-lasting visual tasks. I am having the exact same issue, but I do not believe that it is an issue with the thunderbolt adapter as I can see the Kindle in finder. Your Kindle ebooks will be in the Epub format. After you’ve chosen the books you want to convert, select Convert to EPUB.

Epubor Ultimate will begin to remove the DRM and place the book on the right hand side. Is it possible that the thunderbolt adapter and Kindle wire aren't working together? Or is it the new Mac or the new Calibre that's having problems? Select the book you want to convert and click double-click it. Calibre on my new Mac doesn't have that notification. I noticed that whenever I plug my Kindle into my old Mac, Calibre will pop up a notification that says I have to change the USB preferences on my Kindle to transfer files. I've gone into the Calibre preferences and clicked 'Debug Device Detection' in the Misc. I've also gone into my Kindle preferences and made sure the USB preferences say 'File Transfer'. I've restarted my Kindle, Mac, and Calibre but it doesn't work. Meanwhile, my old MacBook Pro and Calibre still do recognize my Kindle. However, whenever I plug in my Kindle 7 (9th Gen), Calibre doesn't recognize it. I downloaded the latest Calibre and transferred all of my books onto it. I recently bought a brand new MacBook Pro (Big Sur OS).
