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

Hi,

+44 is the International Dialling Code that is needed in some updates on OS X 10.12.5

Technically the Mobile Service's lead five digits are the "Area" code of a British Phone number. The bit you list as 71234.

Whilst the symptoms are similar to the Original Question in this 17 page Thread your issue is in fact different.

Yours relates to how Messages handles (or rather does Not) the info from the Contacts app when the lead Country Code is missing.

See this Thread Re: iMessage not displaying international dialling code instead of contact name

Previously the iMessages account had a separate Pane that slide out to say which Country you were is and this caused the Code for your country to be added to those numbers not given one in the Contacts.

Later versions relied on how th OS found out where it was and this was passed to Messages.

There seems to be an issue at OS X 10.12.5 and for some people the method on how they got there.

The issue does not exist in Mavericks.

Hi! I had the same problem. Here's what fixed it for me:

On my Macbook Pro

1. I selected the "Messages" App.

2. Then at the top left corner of the screen, you'll see your little Apple icon, beside that is the selections of "Messages," "File," "Edit," "View," "Buddies," "Window," and "Help."

3. Click on "Messages."

4. Then, click on "Preferences."

5. Then you're going to see two tab options "General," and "Accounts."

6. Select "Accounts."

7. Make sure you are logged in with your Apple ID on that. (That was my problem, I was not logged in with my Apple ID for the Messages Application on my Macbook).

8. After that, you should be all set up.

9. I restarted my laptop after I did this. Afterwards, I went to my iPhone and selected Settings > Messages > Text Message Forwarding, and I saw that my Macbook is connected. (I didn't see that before).

Hope this helps!

Hi,

This can be because your My Card in the Contacts app (or Address Book) is not showing your details.

It can also be caused by the Sync process between Mac and iOS devices for the Contacts app being messed up.

In the Contacts app go to the Preferences and check the "Accounts" options and see how you are Syncing he info.

It should be only one method (iCloud, Yahoo, Google etc.)

It can be caused by a partial Login to the iMessages server.

Try Signing Out of the app. Followed by Quitting it for a few minutes before reactivating the Apple ID

I have the same problem as eh0608 but what you suggested didn't seem to work. iMessage is working on my iPhone and it seems like it isn't an issue with my apple ID either. After calling Apple, they think it could be possibly because I'm on a university wifi, but I know my friends on the same network are not having the same problem.

Hi,

Start with the Apple ID site and the Manage ID option.

Check your Apple ID is verified and also that any Alternative email including the Recovery ID is also verified.

Check in Messages > Preferences > Accounts > iMessages account that the Apple ID is actually set to be active "Receive At" option

Same for any other email you have added.

In Contacts app check the Preferences > General section is set to the same Country/Region as the computer.

In System Preferences > Date and Time make sure the Date and Time are correct including the Time Zone and Daylight Saving if it applies.

It is worthwhile setting the Automatic Time Server function.

In the Finder > Go Menu > Go to Server enter ~/Library/Preferences into the dialogue box that appears.

In the Preferences find the com.apple.imessage.bag.plist file and (With the Messages app Quit) drag it to the Trash.

This file will hold the server the iMessages account is trying to use.

(Restart the app afterwards)

i have the same problem as mentioned and this suggestion did not work 😟 any other ideas? this started a couple of days ago, with me making any changes, and most importantly it WAS working fine

thanks in advance,

eric

Hi,

Try a PRAM/NVRAM reset.

Hold down the CMD+ALT+P+R keys until you hear three Start up "Bongs" at a computer restart.

I've been experiencing this same issue for the past week and have tried all these things, but to no avail.

Any other suggestions?

I can't even send an iMessage to my own phone number from my computer -____-

Hi,

Do you have any other account active in Messages on the Mac ?

It can be very difficult to ascertain if the iMessages account has logged in or not.

It has no Buddy list like the Bonjour (and other accounts).

There is nothing in the main Messages Window to say the iMessages account is On.

In the Main Messages window if you try to start an iMessages connection does it read "iMessage" in greyed out characters in the Text Field box ?

Also try deleting the com.apple.ids.service.com.apple.iMessage.plist one as well whilst the app is Quit.

When you restart the app you will need to re-enter your Apple ID and accept the pop ups about what the iPhone is using.

I have no other active accounts in iMessage.

I do see iMessage in the text box while it is unselected as you described and pictured.

However, I am unable to locate that file you specified. It is not in ~/Library/Preferences/

Hi,

On re-reading I seem to have copied the wrong info across.

It should be this one:-

com.apple.ids.service.com.apple.madrid.plist

I deleted that file and I don't notice anything different. Still can't send/receive iMessages.

Hi,

I just wanted to chime in here and say that I have been having this problem for MONTHS. I have had my mac for about 4 years and have never had a problem. Then all of a sudden about 6 months ago it stopped working. It has also stopped working on my iPad, but works fine on my iPhone 5. I have taken it to the Apple store, where they even tried messaging the store's iPhone, and still received the same "User is not registered with iMessage" error. They couldn't figure it out and told me they had to "Escalate it to the engineers". I waited about a month, until I finally called and they told me to try "logging out on all devices and logging back in" as if I hadn't tried that. They then assigned me a "Senior care rep" who asked me to try a bunch of things with no success. The Senior care rep then told me he would go back to the "Engineers" and call me in a week. I haven't heard from him in at least a month - just haven't had a chance to call back and devote every evening to talking to people on the phone trying to fix this problem. I really just don't understand how a basic feature could just not work for some people, and Apple has no idea how to fix it. If ANYONE out there knows how to fix this problem I would be so incredibly grateful.

I've been having this issue for a couple weeks, an another one of my friends is, too. Facetime is working perfectly on my computer, but I cannot send or receive iMessages from. When I look at the app, it shows me a one-sided conversation of the messages that I have sent, but does not show me anything sent to me from other iPhones (although it does sometimes show the blue dots indicating that someone is typing, but never shows me a message from someone). The contacts are all red, "not registered with iMessage" when I know they are. It is working fine on my iPhone and iPad. I have deleted the 4 files that Ralph suggested in this and other threads and double checked my account and signed in and out a million times. Apple will not help me because I have downloaded Yosemite beta (the problem started before the download, and I downloaded it hoping to fix it). The only "solutions" I have seen are when people say it magically got better overnight. Does anyone know what I can do?

Hi,

The "overnight" fix does suggest that restarting the computer may be involved as it is likely then that people turn their computer Off.

I would try a PRAM/NVRAM Reset by holing down CMD+ALT+P+R at Start up until you have heard three Start Up Bongs.

I would also consider using a Safe Boot
