I have two Mail.app plug-ins installed: "GPGMailLoader.mailbundle" and "Smallcubed MailSuite.mailbundle". Currenly, GPG is enabled, and works, and MailSuite is disabled.
However, when I toggle either plugin (i.e. MailSuite to on or GPG to off), and restart Mail, the change hasn't taken. So I cannot use MailSuite, nor disable GPG.
I have tried:
- Reinstalling MacOS Mojave in-place (did not fix).
- Creating a new user (everything works for new user).
How can I further investigate this?
