Since I have High Sierra installed, I cann't send iMessage. It shows "Not delivered", but incoming messages works properly. I did try to turn on and off iMessages, restart, activate two factor authentication, but it still doesn't work.
Mac mini, macOS High Sierra (10.13)
Hi IBG,
In another thread (I referred to in this thread), the following worked for me:
1) Close the Messages App
2) Open Key Chain Access
3) Select your main keychain (usually the user name) at the top left side
4) Select "All Items" on the lower left side
5) Search for entries of "IDS"
6) Highlight and delete all entries that has IDS.
7) Search for entries of "FaceTime"
8) Highlight and delete all entries of FaceTime
9) Search for entries of "Messages"
10) Highlight and delete all entries of Messages
11) Reboot
Optional 12) Test it out. If it doesn't work, zap the PRAM a couple of times, then try again.
It was scary because it mentions something about not being able to open previously received chats, but I found the was not the case. I did it and it cleared up the problem for me. I had A LOT of old Message Encryption and Signing keys. Probably some old ones were incompatible or one of them was corrupted. Hope this helps.

Hi,
Try Signing In and Out (Quit in between).

I have the same issue. I saw a post for an other OS in which bad (incompatible) Keychain entries was the cause of the problem. In that post, the Sr. Tech at Apple suggested deleting a number of Keychain entries. Post is located here: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&v ed=0ahUKEwixm5i6r4TXAhWM7oMKHee9A1oQFggo…
I have not tried it yet. I am out of town and cannot get to a full backup until I get home. Don't want to take the chance of deleting something I shouldn't without that backup available. 🙂

Zap the PRAM! This seems to have worked for most people.
Pls do the update. It solved my problem.
Try the link from Jim Martin’s post. It solved my problem right away. With deleting some keychain entries, I don’t have any problem with Facetime / iMessage and feels like those two apps are running more smoothly than before.
I tried this and it worked for me. The fix is a little more intrusive than I think it needs to be (removing all FaceTime and IDS entries). I stuck to just removing 'messages' entries and it did fix iMessage.
Apple have no idea what the issue is and this is happening to so many people, everything they have tried has not worked and now support have given me no option but to only use iphone to send and receive messages until they find the issue and they have no idea when that will be.
Hi,
If the Apple ID is not logged in but is using the iPhone Number on the Mac to Receive at least it is possible that the link with the iPhone number will stay live to allow SMS to work.
All this needs is that at some point the iPhone Number and Apple ID were linked for SMS and then that the two devices on your LAN are still using the Apple ID for the SMS info to be forwarded to the Mac.
The reverse can happen on the iPhone whereby the Number gets deselected (not a User choice but know to happen now and then).
If the Apple ID is still a Receive and Send option then the iMessages get through via the "sync" copies.
The active link tends to be time limited when on device goes Off line.
The Users Tip details things you can try before phone Apple Support and moving up the chain until someone high enough can look at the server and say if your Apple ID use from your Mac is blocked.
The Serial Number makes it Device Specific and it also leaves other apps unaffected.

Dear all,
I have the same problem. I have been in contact with Apple service Germany (2nd level). They have been extremely helpful and willing to solve the problem. However, even after one hour of phone call and many attempts, the problem has not been solved.
After the upgrade to High Sierra, the Messages app does not deliver my messages anymore. I can still receive them.
I can send normal SMS through the hands-off feature, but not iCloud. I have also tried in safe mode and to create a new mock user account. Nothing has so far helped.
If anybody has experienced a similar problem and she/he knows a solution/fix, I would be very grateful to her/him to hear about that.
I also use Apple Key Chain and I have not tried to disable it yet.
I wrote it in my first post, I have problem only with sending iMessage from my Mac. Receiving iMessages and SMS and sending SMS works properly. iMessage on my iPhone works fine.
See my Account settings, everything looks good.
But when I send iMessage from my Mac, immediately I see "Not delivered"
In case I send SMS (green messages), it works. Only outgoing iMessage from Mac doesn't work.
I have the exact same issue. Sending iMessages started immediately after upgrade to High Sierra. It has also worked fine before.
I see all incoming messages including sent iMessages from my iPhone on the Mac. It is only sending iMessages form the Mac that do not work.
My settings is similar Zedex70.
To add to the problem:
From time to time my account in Messages on the Mac is set as Passive even if the activate tick box still is set. If I then try to log out then I am not able to log in again for many hours. If this happens then FaceTime will not log in either.
At the moment I am logged in again. Receives all messages but cannot send iMessages on then Mac. It is working on the phone.
I tried almost everything. Så it must be a server problem, a bug in the High Sierra or my appleId in connection with iMessages.
There is a lot in the system log, but I do understand to read it and see if it mean anything.
Hope Apple will solve the issue.

Hi,
I am not using the iCloud > Keychain option.

Sorry, I don't understand you. I think you have no this problem, then if you have or haven't enabled iCloud Keychain options is not matter for my situation. I need to use iCloud Keychain, I'm using a lot of passwords trough my Apple devices. I don't want to retype logon informations from one account to another manualy.
High Sierra won't send iMessages
