Cannot open books in Apple Books: "formatted incorrectly"

On my iMac I cannot open any books (nor samples) in the native Books app. Dialogue box says: "Cannot open book. It is formatted incorrectly or is not a format that Apple Books can open."


I restarted he computer. Updated from Monterey to Ventura, etc. and no success.


Books do open on my other devices. I have hundreds of books I read on the Mac.


Any suggestions would be welcomed.


Thanks.

Hello jbranden

  1. Go into your books app on your Mac
  2. Don't go fullscreen
  3. On the top of your screen you should see a label with "Account" on it
  4. Push that and you should see an option called "Authorisations"
  5. Push that and authorise your mac
