Q: iMessage unread count incorrect

I found this solution from apple.stackexchange.com:

1. First close the Messages app.

2. Open the Activity Monitor and quit the Dock process; this will restart the Dock process!

Good luck.

Thanks, that was annoying.

The answer from Tomer is useful in that it solves the symptoms, but is there a way to solve the problem ie. make sure this doesn't happen over and over again?
Or is this a known bug which isn't scheduled to getting solved?

Thank you very much for your advice which solves problem.

Quitting messages and Quitting the Dock process in activity monitor did NOT work for me. Still have "wrong" unread badge count on my Messages icon.

Dock Reset - for Launchpad  only Launchpad Reset

Try doing a Dock restart using the following Terminal command:

killall Dock

Log out/in and test. If that doesn’t work, you need to look in your user Library/Applications Support/Dock for the .db. Use the Finder “Go To Folder” command. Enter ~/Library/Applications Support/Dock.  Move the .db to your desktop.

Then try a dock reset.

Applications/Utilities/Terminal enter the command

killall Dock

Log out/in test. If it works okay, delete the .db from the desktop.

If the Dock is the same, return the .db to where you got them from, overwriting the newer ones.
