Use iMessage on my Mac & iPhone. However, not all messages I’ve sent or received from my iPhone appear on the Mac (despite having all contact details the same), though the other way round is fine. Any suggestions?

internet connection on/off? I’d get issues when messages would get sent or received as text (green) not iMessage (blue)…

As Kcal says, plus messages to and from non iphone …erm… phones.

No, it doesn’t seem to be that. Some of the messages not syncing have been sent/received as iMessages. These are definitely ones going to Apple products…

Got the same problem.
No idea how to rectify it so I’ll be watching this thread.

I sometimes have to quit (Command+Q) iMessages on the Mac in order to have messages come through.

Will try that. Someone else had suggested signing out of both and signing back in. Didn’t work.

I’ve also just noticed this problem today. I don’t think it’s a coincidence so i’m just going to leave it to fix itself…
