I offer you to take a non-Dem book and drag it out of Books and try to open it in another reader. It simply doesn’t work. And that because the package is recompressed in a non-standard way. This has not changed. It’s the reason calibre says the file is not valid.
It is also the reason decompression programs DO exist. The resulting file then being a standard epub.
There are a few reader apps out there that will load a transferred iBook file. But the issue in general remains on the most recent versions of Books.
The OP and other comments are correct.
Right now I use eCanCeusher. (Disclosure: not affiliated )
It DOES work most of the time. And actions CAN be scripted. But it only does one book at a time, despite the batch claim.
But again it appears inconsistent. Though that could also be my scripting that fails as well.
