Hi, I’ve been having this problem for some time. Mailbutler is causing Mail to freeze. When I uninstall the plugin, Mail works. I do have other plugins, and it could be that Mailbutler is in conflict with one of them. I suspect Daylite; however, Daylite is a crucial piece of software for my business. Do you have any ideas how to diagnose this problem? Thanks,
To the best of my knowledge, the current version of Daylite and the most recent version of Mailbutler are getting along well right now. You can always find the most recent version of our plugin here:
If you’re a Mojave or Catalina OS user, please do the following: go to Mail-Preferences-General-Manage Plug-ins and re-enable Mailbutler.
