Jan 20, 2019 at 22:27 comment added SPRBRN Yes it's like a fingerprint. I can unzip it, then open all XHTML files in an editor. No technical limiting DRM, like I said.
Jan 20, 2019 at 21:50 comment added kumowoon1025 Oh, kinda like the fingerprint being added to DRM-free content on iTunes? I feel like it should work as well then... Where did you buy the book from? The OPS should be an xml file describing it within the OEBPS folder if it isn't a folder itself. Also take a look at the META-INF files to check that there is no DRM.

Jan 20, 2019 at 21:42 comment added SPRBRN Social DRM adds personal information to the content of the book. It is not like Adobe DRM which is an encrypted format. Like I said, I can unzip the contents, so it's "open".
Jan 20, 2019 at 19:48 comment added kumowoon1025 What is social DRM? Books.app doesn't support epubs with drm afaik
