macOS Sonoma + GPG Mail: Lacking MailKit capabilities prevents release
Everything you need to get started with secure communication and encrypting files in one simple package leveraging the power of OpenPGP/GPG
Key points: Missing API functionalities which block the release of GPG Mail as a Mail Extension
Four of the major functionalities missing in the first official release of macOS Sonoma are:
Entire message data is not always passed to the extension making processing the encrypted message impossible Reliably encrypted drafts Support for setting the default state of the sign and encrypt button in compose windows which can lead to dangerous side-effects Sign and encrypt button could go out of sync with internal state, if keyring changes are detected
Probably a good time to reach out to Apple: https://www.apple.com/feedback/mail.html
