  1. I tried this with no success. I finally called Apple Support and they asked me to boot in safe mode (maintain shift key while powering-on the mac until the beep and the apple logo). This actually did the trick and helped me logging in back again under iMessage and Facetime with my appleid. I was not able to do that before right after the upgrade.

  2. Jennifer Rhodes says:

    All the above works for me, but pics and videos… they show they are fine on the Macbook pro, but they she “downloading” on the phones, both mine and the people I am sending it to.

  3. Phil Gonsoulin says:

    I spent the afternoon with escalated Mojave Tech Support. My MacOS broken Messages app when texting Android devices showing “Messages Not Delivered” has been fixed:
    On each iOS device, go to Settings > Messages > Send & Receive > Apple ID > Sign Out. FaceTime is joined at the hip with Messages, so then go to Settings > FaceTime > Apple ID > Sign Out. Then on all Macs signed in to the same Apple ID, go to Messages > Preferences > iMessage > Sign Out. Then, on all Macs, launch FaceTime > Preferences > Log out. Then, re-boot all devices and repeat all in reverse order. FIXED!!

    1. Tony Rodgers says:

      This approach (Phil Gonsoulin’s) seems to have worked for me. It seems odd, but now that I’ve signed out and restarted all my devices and signed in again, Messages seems to working properly again. Thanks for sharing your experience!

    2. Thanks Phil Gonsoulin, that fix did the trick!

  4. I’m having an issue with viewing images in imessage. I used to be able to just click the pic and see it bigger in preview. Now, I have to control click, services, open, confirm service, run service.
