I updated K4Mac to 1.20.2 (47082), planning to test the chmod workaround to avoid KFX. But before I applied it, I downloaded a book to see what KFX looks like on download. Instead, I got AZW3.

I deleted all books in My Kindle Content folder, then re-downloaded a dozen books with Enhanced Typesetting. I received AZW3 every time. My K4Mac 1.20.2 seems incapable of giving me a KFX book.

I then used the chmod command and got the same result enaid1 did (unable to change file mode, operation not permitted), so Amazon seems to have altered the permissions to block this workaround. I then used sudo chmod. I didn't get an error message, but I have no way of testing whether this blocks KFX, since I was getting AZW3 for all my books even before using the chmod workaround.
