Found a strange issue today with my new M1 Pro MBP. I used Migration Assistant to move everything from the old 2015 rMBP including the mapping of my iPad Air 4th gen. Looking in Books on the MRP I see a total of 79 books, 9 series, and 70 PDFs. Plugging in the iPad Air and doing a sync with All books selected for sync results in only 19 books, 10 series, and 1 PDFon the iPad. Tried rebooting everything, the iPad is trusted by the MBP, and even tried selecting “selected books” and unchecking everything, syncing, and then reselecting All Books followed by resync again. No luck.
Finder…when the iPad is plugged in…only shows a subset of the books and none of the PDFs that are visible in Books.
Any ideas on magical incantations I should try? I could do a local backup and then restore from backup if necessary…but since the backup would include only the limited number of books either in the Finder under Books or o the iPad I’m not sure that would do anything.
Since I only see a limited number of books/PDFs in Finder as options to select for syncing when the iPad is connected…perhaps it’s a matter of nuking some file on the MBP instead…googling didn’t reveal any answer although I did log out and in to iCloud on the iPad and uncheck/check the Books option in iCloud on the iPad based on what I did find. I poked around in ~/Library and didn’t see anything obvious where Books preferences or the prefs for the iPad might be.
