For some reason my iMessage just started not syncing to my MacBook Air. I can 'send' iMessages but not receive on my MacBook Air.

Hi there, ToddAfrica.


It appears that messages on your iPhone aren't appearing on your MacBook Air. You're able to send iMessages, but you can't send SMS/MMS messages from your Mac, and we're glad to provide assistance.


How to forward SMS/MMS text messages from your iPhone to your iPad, iPod touch or Mac - Apple Support -- On your iPhone, go to Settings > Messages > Send & Receive. On your Mac, open Messages and choose Messages > Preferences > iMessages. Make sure that both devices are signed in with the same Apple ID. Then, on your iPhone, go back one screen and check Text Message Forwarding to make sure your Mac has been selected. If it is, deselect your Mac and restart your iPhone. Once it's back to the Home screen, turn Text Message Forwarding back on for your Mac and test the issue.


Feel free to get back to us with any questions or problems you may have.


All the best.

As stupid as it sounds, I got it to work this way. And BTW, I do NOT have messages enabled in iCloud.

Delete off your computer the messages that wouldn't send.

Sign out of icloud on both devices.

Turn off imessage in the messages setting of the phone.

On your iPhone, delete "test messaging forwarding to devices" under the General > Messages


Close apps.


Restart all devices (saw that coming, eh?).

Sign in and enable imessage on phone.

Sign in on other devices.

Tried it and all the other steps. I have MBA 2017. This only happens in Monterey. Big Sur was not an issue, Catalina, Mojave on my MBA 2017. I have also signed out completely, reformatted the HD and reinstalled the OS Clean and updated to Monterey. Again it only happens in Monterey. I can send and receive on the Mac and it syncs on all my devices, but sending sending from an iOS device or another Mac with iMessage, those messages will not show up/sync with the MBA 2017 in Monterey. After several experiments the 2017 MBA is probably getting old and Apple is just not paying attentions to its quirks with the new OS. So I'll just revert it back to Big Sur and leave it there.

So I had it stop working for me again, after I signed in to iMessage and FaceTime with Apple ID. So the glitch is something with those.


What fixed this for me was going to my phone, going to Settings --> General --> Reset --> Reset All Settings. I did NOT sign into iMessage or FaceTime with my Apple ID, and did not check send as SMS under iMessage settings and have not had a problem in the last three or four days.

Thank you, SnickZ, for taking the time to respond. Unfortunately, even following your suggestions, most importantly that both devices are signed into the same Apple ID, the two devices still do not appear to sync.


In short, iMessage seems to be working perfectly fine on my iPhone. I can send and receive messages from this device.


My challenge is that the messages SENT from and RECEIVED by my iPhone do not show up on my Messages app on my MacBook Air.


However, I CAN SEND messages from the Messages app on my MacBook Air and these show up on my iPhone but CANNOT RECEIVE messages/responses.


Does that bring any clarity?


Grateful for any help...

This is the fault of the latest update. I updated a few days ago (I’m always late to the party) and immediately after this update I couldn’t send texts with my iPad. After several days of resending, power cycling, going from one device to another, the issue persists. I got messages to/from one recipient to populate to both devices, but still not effortlessly and consistently like it was before the update.


One of the reasons I pay thousands more for Apple devices is ease of use, consistency, and admitting to and fixing what they know are their problems immediately, if not sooner.


Apple, take note and fix this problem! I shouldn’t have to change settings that weren’t broken before you fixed them!
