How to edit m4b audiobook metadata in Catalina? In Catalina it is not possible to edit audiobook metadata anymore as it was possible using iTunes in previous macOS versions. I tried a third-party tag editor (kid3), successfully edited the audiobook metadata, but still, when I import the audiobook into the Books app, the metadata is wrong.
What could possibly be going on, is there anyway I can work around this issue?
I used subler BY Damiano Galassi to change it.
