Has the recent macOS 10.14.6 (18G9009) update removed Mail Manage Plug-In

It appears that the latest 10.14.6 update has removed the "Manage Plug-in" setting in Mail.

I tried all the terminal commands to re-enable it, such as "sudo defaults write “/Library/Preferences/com.apple.mail” EnableBundles 1", "defaults write com.apple.mail EnableBundles -bool true", "defaults write com.apple.mail EnableBundles -bool YES", and "defaults write com.apple.mail BundleCompatibilityVersion 4", but nothing has worked.

I'm using SpamSieve to filter the barrage of junk mail and it now longer works since the update.

I just applied the 10.14.6 (18G8012) update from yesterday and the Mail Plug-ins button is still on Mail > Preferences > General panel. There is no 18G9009 update pending in my Software update.

Attempting to apply defaults write commands intended for an earlier V4 Apple Mail when Mojave Mail is a V6 entity simply does not work as they are not supported in the .plist.

Check SpamSieve's site to determine if they have updated version software available.

This seems to be caused by a macOS bug where Mail no longer has access to read its own preferences. You can see this because changes made in the Preferences window are not retained when launching the app. One possible workaround is:

Open System Preferences > Security & Privacy > Privacy > Full Disk Access.
In Terminal, enter "open /usr/sbin" and press Return.
Drag "cfprefsd" from that folder in Finder to the Full Disk Access list.

My bad, I didn't realize this was a developer release as the update didn't mention the type of release at all. Will report through appropriate channels.
