MacOS – Unread message in Messages not being set as “read”

macosmessages

So, I have run into a bug where iMessage syncs my normal SMS-messages with Messages on OS X.

The problem is that the message doesn't want to get read. I click on the sender (automatic SMS from a computer notifying me of an email), the (1) disappears for a second and then returns.

The message does NOT show up unread on my iPhone or iPad,

I've tried the following:
– Restarted Messages
– Closed the conversation
– Deleted the conversation

But no luck.

I'm going to restart my computer now, but in the meantime I hope you can come with a solution. Maybe something like "Mark all as read"?

This problem is fixed in a new release of 10.10.2

I'm currently running 10.10.3 and am having this issue again, so not fixed in 10.10.2 unfortunately. Have experienced in the past, major pain.

The following works for me every time

In the Finder > Go Menu > Go to Folder type (Copy and Paste) ~/Library/Preferences into the Dialogue box.In the Preferences find the com.apple.imessages.bag.plist and drag it to the Trash.

(found on https://discussions.apple.com/thread/4486753?start=0&tstart=0)

Then reboot the machine. The post says to reboot messages but I always have to reboot the entire computer for this to work properly.
