iMessage on my mac says every contact is not registered with iMessage

Hi,

That sounds like someone has tried re-setting the iMessages servers with only a partial success.

I would try restarting the Mac and see if that makes a difference.

Hi,

It would be also worth those involved to also give Feedback.

Either use http://www.apple.com/feedback/

or http://www.apple.com/feedback/ichat.html

I personally tend to use the iChat one although it have been a long whole since the change.

If you don't have an AIM Screen Name but have an Apple ID issues by Apple (ending @mac.com, @me.com or @icloud.com) then put that in the box as it is a valid Screen Name.

Use the Free Text Area on the iChat page to add details such as the OS version (the drop down lower down the page is often behind the times) and the Messages version (that drop down is well out of date) as well as a description of the issue.

Hi,

Despite Apple owing the Site and providing Hosts (Moderator) staff and some "Community Specialists" they rarely read the Threads for issues.

Sometimes some issues will get noticed and an Apple Doc set up with what is thought to be the fix (in most cases that was also discovered on the boards by trial and error) such as this one FaceTime, Game Center, Messages: Troubleshooting sign in issues

In the case of this error the Regular Posters have been running through a gambit of ideas with people who have posted about the problem.

After one person did a Clean Install (Erased the Drive and created a new Mac User Account without migrating from a Backup) and set up the iMessages account in the Messages app that way it become clear the issue is either the Mac Serial Number which is used for an Auth Token in the Keychain or something about the Account on the iMessages server.

Based on that info I have Sent Feedback (and suggest other people do as well)

And I posted in the Lounge (where Level 6 Posters and Above can post) and reported the problem in that hope that two routes are better than one.

It really doesn't matter how much you love Pete, pleading here does very little.

Hi mariofromfranklin,

On both the Mac and th iPhone the System Preferences > iCloud or the settings > iCloud are both set to sync the Contacts app ?

I would try Signing Out of iCloud on the Mac and then signing in again.

I would also toggle the Contacts option in iCloud Off and then On again.

HI,

In a couple of other threads posters are reporting that it has spontaneously worked for them without doing anything.

The PRAM reset used to work back awhile.

It might now be the thing to reset the Mac end with some users.

Thanks for the info.

Hi,

If it works on your iPhone then essentially there is nothing wrong in that sense with the Apple ID.

If you have then tried everything on your Mac, AppleGothic.ttf Font, Serial Number, Set up items then is issue will appear to be with the iMessages Server and the way it is dealing with the "registration" of the Mac.

This does make it an Account issue but it only effects the iMessages server when logging in from the Mac.

You have to make it clear you have an Account issue when you phone up or they will try to say it is either Software or Hardware and try and charge you for out of Warranty calls.

Hi,

If, and it is a big if, enough people have reported this via Feedback and the fact the issue has been raised with the Hosts may mean we have reached critical mass as it were and some engineers have looked at this.

It may be that the server have just reset themselves in the normal course of things (although less likely)

Lets hope it is an Apple intervention and that it is a permanent fix.

Thanks for letting us know.

Hi rosenbst,

Are you saying that you had the issue where all Contacts were turning red in the "To" spot and you were getting the Not Registered message to now individual messages have a exclamation mark next to them saying they are not delivered ?

(I.e. the issue has changed).

Hi,

In that case restart the Mac holding down the CMD+ALT+P+R keys until you have heard three Start up Bongs and then let it continue.

(PRAM/NVRAM reset)

Blast !!.

I have a feeling we need to wait for a major Apple reset at their end.

Hi,

Unfortunately I think we may see a lot of this.

I also think it is a sign that Apple are working on it.

Hopefully it will settle down soon.

Hi,

At this point, despite the fact the issue has been reported to Apple Via Feedback and via the Hosts on these Discussion Boards, I would contact Apple Support and tell them you think you have an Account problem with iMessages.

Account issues tend to be fixed for free (they do try and tell you it is a Hardware or Software issue). Ask to speak to a Level 2 person if you are having no luck.

Hi,

I must admit I have seen this Devices List that shows an extra iPhone that I delete the settings from before I then did Factory reset.

I think that to get it removed you may have to ask Apple Support.

Hi,

We know from one particular Error Messages the Messages shows to some people that Apple Support have to sort that issue at their end.

We also know that since OS X 10.8.2 which update Messages to version 7.0.1 that the Mac Serial Number has to be readable on the hardware to the System Info app as it is used to create the Auth Token needed when communicating with the server.

(i.e. some issues would seem to be specific to individual Apps based on how they Login to the server - why the server is rejecting info that did work is another question).

See if the Apple Support People will reset you account on the iMessages server.

Hi,

Which Updates ?

Only something like an OS X update such as going from OS X 10.10 to OS X 10.10.1 is likely to cause this unless you are updating a FONT app that might be clashing with Font Book and turning certain Fonts Off.
