I don't know if this is just a Ventura thing; but I have a few pdf books that I owned and read on iPhones and iPad easily on the Apple Books app; but when I wanted to read it on my Mac OS the pdf books would open to preview instead of internally in the books app where the files exist in. Was wondering if anybody else can test this out. I have reported this issue since Apple Books Library literally has a pdfs option and yet on Mac OS it would open on a separate app
