I've tried opening and closing the app, deleting the whole conversations from the individuals it says there are unread messages from, turning off the message notification badge and turning it back on, and combinations of that. But, I still have "3" unread messages on the MacBook (but none on the phone or iPad).
This is a new issue since Yosemite.
Thoughts?
