Mojave Mail does not have 'Manage Plugins' button

I uninstalled the plugin (Mailhub, which is explicitly listed as supported on OSX Mojave) and reinstalled it when Mail was not running. I enabled full disk access as described, and restarted Mail. Still not button to manage plugins. The plugin installer says it was successful.

Also, I cannot view the contents of the ~/Library/Mail/Bundles folder, even using sudo privileges. I have full admin rights to both of my Macs.

A reboot of the machine may be in order.

Mojave Mail (v12.0) doesn't pick up mail plugin (i.e., foo.mailbundle)

*The way I have always dealt with the mail container is as follows:

Quit mail.

Finder>Go>Go to Folder, copy & Paste:

 ~/Library/Containers/com.apple.mail

Highlight all the contents in this folder

Then right-click and choose "New Folder with Selection”. Do not move the new folder from this current location.

You can close the Finder window.

The next step will be to restart the Mac and test

After the computer is restarted, open the Mail Preferences to see if it opens properly, with your "Manage Plug-in.." visible.

Then you have a permissions problem in your home folder. Nothing in the Home folder is restricted from the user.

I've seen references to this problem but no fix that works for me. Under Mail --> Preferences --> General, I do not have the button to 'Manage Plugins'.

I have tried 'defaults write com.apple.mail EnableBundles -bool true' and restarted, but the button still doesn't show up. \

And what exact Plug-in were you hoping to manage? Is it Mojave compatible? Check the developer website.

Quit Mail.

If it is not present then Launch that associated app/ update the associated app you wish to integrate with Mail Preferences:

If you were using Mail plug-ins when you upgraded to macOS Mojave, click Manage Plug-ins to enable them again.

From >System Preferences>Security & Privacy>Privacy> Full Disk Access you may have to give it permission here.

If it is not already in the list, you may have to add it.

Relaunch Mai.app>Preferences>General

By default, there is a Manage Plug-ins… on the Mail : Preferences : General panel with Apple Mail in Mojave 10.14.4. It is present on two different Macs here with Mojave 10.14.4 installed.

There is no assurance that any defaults write command that you may have found on the web will now work with Apple Mail, or any other Mac application.

Do you have any Mail plug-ins installed? There would be no reason to display the button if you don't.

The would be stored in either /Library/Mail/Bundles or ~/Library/Mail/Bundles

If you do have those folders with mail bundles in them, manually remove the plugins and restart Mail to see if it resolves your problems.

…or mine

FWIW, this works. Quit Mail. Type this line in the Terminal…

sudo defaults write "/Library/Preferences/com.apple.mail" EnableBundles 1

Restart Mail.
