I had Messages.app when I got my mac a year and a half ago and it worked great.
However, since a few weeks ago all my contacts in my previous conversations appear in red (as if they do not have an account).
What's even more curious is that I can see when people are actually typing (I see the 3 dots (dis)appearing), but I only get the message on my iDevices.
Solutions I have already tried :
- Restarting messages
- Signing out/in my account
I am now out of solutions, do you guy have any ideas what the problem might be?
NB : My OSX is up-to-date with 10.9.3
Edit : It also doesn't work on my iPad (iPhone is still OK, receiving iMessages as iMessages). Edit2: I hoped updating to Yosemite would help. But no :(
