Re-enable the Mail plugin on macOS Mojave

Today is macOS Mojave day. And while DEVONthink 2.10.1 is working fine on Apple’s latest incarnation of the Mac operating system, the new security measures do interfere with DEVONthink Pro Office’s Mail plugin. Mojave wants to know that you trust our plugin and have the intent to run it. To (re)enable the Mail plugin please follow these steps:

  1. Enable full disk access in System Preferences > Security & Privacy for DEVONthink Pro Office.
  2. Install the Mail plugin.
  3. Enable the plugin in Apple Mail with Mail > Preferences > General > Manage Plug-ins. The DEVONthink plugin is named “DEVONMailConduit-SnowLeopard.mailbundle”.

And voilà, the additional commands for archiving messages and mailboxes are back.

P.S. We have updated the Mail plugin numerous times since OS X Snow Leopard but, luckily, we were not forced to rewrite it competely. That’s why it still has “Snow Leopard” in its name. Now that it’s visible to the public we’ll name it a bit more friendly with one of the next releases.

P.P.S. The next update for DEVONthink Pro Office will be able to install the plugin without that you have to manually grant it full disk access. You’ll only need to enable the plugin manually should you need to reinstall it.

    If this is supported why does Mojave Mail 12.0 disable your plugin on startup? I cannot get your Mail plugin to work, I wouldn’t have upgraded if you didn’t claim that it was supported.

  8. Apple dislikes third-party Mail plugins but doesn’t disallow them either. They have disabled *all* third-party Mail plugins on major system upgrades all the way back since Mac OS 10.0. Reinstalling the plugin always made it available again, only Mojave now requires additional steps. If you need assistance getting the plugin to work again please drop our support a line and we’ll try to help.

    I don’t have the drag and drop function (Mails to devonthink) after installing the AddIn as describe above. Does anybody have the same Problem, or a solution ?

    @Torben: This would be better asked on our Forums, not in blog comments. Thanks!

    Sorry, Devon, but your plugin is not working with macOS Mojave. It becomes deactivated on each start of Apple Mail. Perhaps the workaround described above is suitable for the Mojave betas but it is clearly not for the release version. Please consider a makeover.

  12. Have you manually activated it in Mail’s new Plugins preferences? Please contact our support so what we can find out what’s going on on your machine. Here the workaround works exactly as described and for many customers it does so too.
