I have a Macbook Pro 13" running El Capitan, purchased in February 2016. For the iMessage app, which I have saved in the Dock, the unread messages badge says there is one unread message and there's not. If I click and hold on the iMessage icon, it tells me which message is unread. And I have viewed all of the messages from that person. I tried quitting and reopening the app – that didn't fix it. I restarted my computer, and that does fix it, but the same issue arises again within a few days.
How can I fix this so the badge count is accurate?
I'm not great at using the Terminal. If you have a suggestion using the Terminal, please be very specific so I can replicate your suggestion easily.
EDIT: I just discovered that the badge count is wrong on the Messages app on my Mac if I have a text message (not an iMessage) unread on my iPhone.

That has happened to me. Try opening the app and clicking on the person who sent the last message (or simply click on all of your contacts). That should prove you have read all the messages and take away the badge. Hope this helps.
