messages stopped working on my iMac computer
I have an old iMac running High Sierra. I use the Messages app often throughout the day. Today I received my new iPhone 11 Pro. My phone is set up and seems to be working fine. But on my iMac, my messages quit working if sending to a non-iPhone account. I don't know if the 2 are related, it could just be a coincidence that messages stopped working when setting up my new iPhone. I have stopped and restarted Messages and I've restarted my computer. Both to no avail.
Does anyone know how to troubleshoot/fix Message delivery on macOS?
The registration can fail and need to be re-established. Before you contact Apple support, I would open messages on the Mac and sign out of your AppleID.
- Sign out of messages with your AppleID
- Check the date / time in the Mac in system preferences. Within 60 seconds of reality should be fine, closer is better of course, but it’s not sub second critical.
- Sign back in to Messages (quit the app and retry after signing out if it’s stubborn). https://support.apple.com/en-us/HT204408
The system should log an error to the diagnostics or the screen if your sign in fails.
Go to Settings->Messages->Text Message Forwarding on your phone and make sure your iMac is listed.
