No notifications from Notification center for Messages app in OSX Mavericks

I likewise installed Mavericks two days ago, and have encountered a number of problems, some more serious than others.

As with Dr. Blair, notifications from the Messages app have suddenly stopped working. In other words, if someone sends me a message while I am in an app other than Messages, a notification of their message arriving is not appearing in the top right corner of my screen.

If anyone has found a solution to this problem, please advise.

Thank you very much.

I have the same problem as those listed above. Also, I'm not getting any notification bubble down in the dock. If anyone has a solution, please advise.

Thanks!

I have exactly the same issue - I installed Mavericks the day it came out and Messages notifications have been working right up until earlier today. No notification, no sound, no dock icon animation when using another app. I hadn't touched any setting related to it. I do get the new message sound when I'm in the app, though.

I am experiencing the very same problem as Dr. Blair. I not only do not receive any Messages notification (Alerts nor Banners) in the top right hand corner of my screen, I don't receive E-mail notifications (Alerts or Banners) either. I do believe there is a glitch. ***APPLE ENGINEERS... PLEASE ADRESS.

Ah, Messages worked this morning [08:44 PDT]. Well, when it does work, the new feature in Alerts is cool. ***Thanks Apple.

Well, yesterday afternoon I ran Drive Genius from my external backup drive and used "Repair", followed by "Defrag". I also used Disk Utility to repair permissions on my internal Mavericks startup drive. Lo and behold, on-screen notifications appear to be working again in Messages. Whether or not this is a result of the things that I did, I am not certain.

However, other issues still exist, such as emoticons sometimes appearing, and sometimes not, either on my end, or on the end of the person I am messaging with.

It appears that I finally got my user picture/Avatar to stick by using the same image in Contacts, Messages and Users and Groups. I also enabled Bonjour in Messages.

Mail app is suffering even worse things, but I won't get into that in this thread.

Quite frankly, this is the worst OS update I have seen in a long time, and I am bewildered that Apple let this out the door in this state. I really like the new tabbed windows, but these other issues really dampen my enthusiasm for Mavericks. 😟

I am having this issue as well and it's absolutely infuriating. No notifications for any messages that come through the Messages app, either through the iMessages, GChat, or AIM accounts.

Seems like Notification Centre is having this issue for more than messages - with me not all emails are showing and I did clean Mavericks instal.

vmfromfl, I was having problems with messages, I did receive a Messages notification on my Mac the other day but haven't since; this is an intermitent proplem with Messages. I agree, I haven't received one e-mail notification since the update.

Experiencing same problem - no iMessage notifications in Notification centre.

I have the exact same problem. It started out all fine, but now magically I don't receive any notifications (badge, sound or in notification center) when a new message has arrived. Thou I haven't changed anything in settings, I did check the notifications center and everything is on so I am guessing it's a bug.

To clarify, I do still receive mail notifications, it's only the Messages.APP which is blocking everything without a reason and it's frustrating because it's now completely pointless I have no idea when someone has send me a message only when I go check it manualy.

I am having the same problem, I am not getting a notification badge on the messages icon and notification centre is not displaying any notifications for new emails or messages, I am also not getting any banners in the top corner for messages or emails or any sounds when new messages arrive.

In the messages preferences 'play sound effects' is checked and I have selected a notification sound. In notification preferences Mail and Messages are selected as well as banner and play sounds.

I deleted the ichat.plist file and now I am getting an app icon badge when i get a bew message but that's it

I had same problem, my got solved by deleting my e-mails accounts and the adding them again.

Same problem here.

It seems Apple is getting sloppier and sloppier with their releases. They need to get on the ball.
