You used to be able to access devtools access to iBooks on macOS using a terminal command. Unfortunately when Monterey launched they replaced the old macOS Books app with, as far as I can work out, a copy of the iOS app. As a reading experience it’s fine, but I can’t get devtools to connect to it any more.
Has anyone got a secret way of doing this?
(if you do, there’s
a bountied question on ebooks.stackexchange that I’ll happily award you)
