How to update cover for audiobooks in Catalina's book app?
There was a question - how to update cover for audiobooks in Catalina's book app? I couldn't find answer for a while, now I have the solution: It is necessary to update metadata of the files you import to iBooks first. Install some application for changing mp3 tags (e.g. Tag Editor) and change the covers of the files you need. Save and after that you can drag and drop files (or whole folder) to iBooks. You will see the covers you need. My god, why is it so so frustrating and complicated, Apple? :(
And why am I asking a question again instead of answer the question? Because it is not possible to put the answer to the question, it was somehow closed without any reaction - see here https://discussions.apple.com/thread/250764149
