Cannot send iMessages on my Mac but can receive them

votefavorite



I changed my main Apple ID email address yesterday, and also changed from my iPhone 5C to a iPhone SE.

Once I did changed my Apple ID email address, I had to sign out of all my devices, and sign back in with the new email cause I was getting error since the apps were trying to log in with the old email.

After that, everything was working on all devices except 1 thing. I cannot send iMessages from Messages on my Mac. iMessage is working on my iPhone correctly. I can receive iMessages on both Mac and iPhone. I can even send SMS (non-imessage) messages on my Mac. Really, all I can't do is to send iMessages from the Mac.

What I did :

- Restarted my computer
- Log out and back in of Messages on the Mac
- Log out and back in of iCloud on the Mac
- Deleted Messages related Preferences files
- Deleted Keychain passwords that were using the old email

Not sure what else to try. Any help would be greatly appreciated. Thanks!

I did this, tried to mark it helpful, and was not able to. It did work for me, perfectly. Happily, I had copied the instruction onto a sticky note, because today, several months later, I again was unable to send messages from my laptop. I went into keychain access as directed, and found that the com.apple.facetime had come back today, at 11:00 a.m. I followed the rest of the instructions, and it worked like a charm, again.

I tried this, but it did not work:

1. go to Keychain Access app in the Utilities folder

2. under the File menu, choose *Lock Keychain "Login"*

3. go to the File menu again and choose *Unlock Keychain "Login"*

4. enter your password when prompted.


I then tried this, and it did work for me:

  1. Close all applications, specifically Messages
  2. Reboot
  3. Open Keychain Access
  4. Search in Keychain Access for - com.apple.facetime
  5. Right click on and delete - com.apple.facetime: registrationV1
  6. Reboot
  7. Launch Messages
