iMessage Delay High Sierra

Is this the "message sound" option your referring too? I've had it turned off for several day's now and still have no luck.

Yes

Yes they are.

Heh heh. Try turning it off. It doesn't come back on. :-) The number you need to type back in doesn't show up on my Mac. Now I broke mine again... Oh well...

Just updated all my devices. Will see if the issue has been resolved. I'll report back.

Mac: macOS 10.13.1

iPhone 6: iOS 11.1

AppleWatch: watchOS 4.1

I'd be surprised if it does. I think it was updating everything to the latest that caused the issue for me in the first place!

Here everything is OK now!

the issue is noticeably better .. but still it's happening that some random messages are still not not synced

Yes, I am all updated. No, it's not resolved.

Stop sending me emails

I am also having this issue! The messages show up on my computer but without proper notification. It's very frustrating! My OS is up to date, I restarted my computer and tried disabling location services as others had suggested. What's the solution? If anyone knows please tell me!

I also have High Sierra, and Messages app is months without updating any activity. Since November. I was in the app just now and two new messages came through right then. But no other active messages that are still on my phone will show up.

I'm experiencing the same issue. It's very interment and annoying to say the least... I've thought of reverting back to Sierra but will hold out hope Apple has a patch soon.

I've found that if I get a message on my iPhone like other's have said, I don't get the notification. Not even on my Apple Watch. So I do take advantage of watchOS 4.0 and the messages compilation telling me the number of unread messages. So when I check the time I see I have missed messages. Then I check my Mac and it doesn't have any. So rather than responding from my watch or iPhone I respond with my Mac. After about 10-20 seconds it seems to hang but then finally sends. Along with sending the message it populates with all the incoming messages it missed. Then works for a while. But then all starts over again.

Really odd if you ask me.

Ok then,

If the Audio server is nothing to do with Messages why did you mention it in this thread ?

I was pointing out that it was unlikely to be the Audio Server that was delaying the iMessages.

The iMessages are Pushed at the registered devices until they Accept them - which tends to mean they have to be On Line and Logged in fully.

The hints about using the High Sierra iMessages accounts and then the iMessages coming through points to it being an issue between the new iMessages client and the Server's interpretation of it being logged in.
