Hello, I bought a kindle book from amazon and downloaded it on my Mac Kindle reader, now I want to convert it to PDF. I read at http://stream-recorder.com/forum/read-convert-amazon-azw-ebook-epub-fb2-t8954.html that Calibre can do it but first the DRM needs to be removed. I used a Calibre plugin to do that but it failed saying it couldn't find the PID. I read elsewhere that Mobipocker Reader could give the PID, I installed the Windows version in Wine but it didn't recognize the .azw or .mobi

Any solution ?
