iMessage NOT syncing across iPhone and MacBook Air

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.

Thank you for this response. I could not figure out the issue but once I verified that all of the "you can be reached at" options were the same on all devices, everything synched instantaneously.

I have solved this one. Please go on your iPhone to Settings - > Messages. Scroll down to "Text message Forwarding", check the device you want your text message to be forwarded. Done.

macOS High Sierra Version 10.13.6

macOS Monterey Version 12.0.1

iPhone Version 15.0.2

The "Text Messaging Forwarding" had solved mine:

> iPhone > Settings > Messages > Text Messaging Forwarding

Thank you.

Here's a cool trick

On messages, go to Messages>Preferences in the menu bar. (Or press Command+,) Go to iMessage (with an @ symbol on top)

Then press sync now and it should be synced. You will know when it is done when the button is no longer greyed out.

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.

I had this problem as well.

Settings > Messages > Text Message Forwarding > Toggle MacBook Air (Mac) to on.

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.

On the iPhone >> Settings >> Phone and look for Make and Receive calls on Nearby Devices >> Enable for the MBA

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!

I am currently synced with my iPhone 11 Pro to an iMac (no issues) a MacBook Pro (no issues) two Mac mini (both intel, no issues) and a new Mac mini (m1). The new Mac mini worked fine out of the box but the last update (3/31/21?) seemed to kill the message sync on only the m2 Mac mini. I can send iMessages but sms does not complete, the bar makes it 90% then freezes then I get told message failed. I can manually sync most of the time from preferences. Nothing seems to help.

I tried the above on my iPhone and now it will only send iMessages from my appleid email not the phone number though it will receive to the phone number and the appleid email.

This is a cluster and completely defeats the reason I have a Mac.

As I reflect it may not have been the update but the installation of rosetta that caused the issue on the Mac mini m1, done in same couple of hours so hard to distinguish.

I started experiencing this same issue a few days ago when I set up my new MacBook Air. Messages synced fine between my iPhone and old MacBook. One thing I've noticed is that it appears to be only texts from non iPhone users are not syncing between devices. Also, I can't send a text to a non iPhone user from my MacBook - they all fail. I've tried all the troubleshooting suggestions and can't get them to stay in sync. On my MacBook, when I go to System Preferences>Apple ID>iCloud, I noticed that Messages is no longer in the list of "Apps on this Mac using iCloud" where you can check and uncheck which Apps to sync. I feel like Messages was listed here as an option on my old Mac. My iPhone is on 14.5.1. and my MacBook Big Sur 11.3.1.

Todd, Apple pushes boundaries and often 3rd party software is to blame for conflicts. You will not regret switching to Mac. Having said that, some issues are hardware related and more difficult to solve.

My single complaint against Apple is icloud. It is a one way syncing service that serves Apple’s interests better than customers to put it mildly. They want everyone’s data on their servers and to treat all devices, including desktops, as peripherals.

Normally, Apple software syncs with no user involvement or issues with its own software that comes with the OS. Typically, iMessage issues are related to Apple ID (which is your email). The password is not considered to be part of your Apple ID.

If you purchased a computer used, for example, and have not te-registered with Apple, the serial will be associated with another owner and you will not be able to sync or purchase anything. A security measure. Check that first!

I have the same problem. iPhone syncs both ways. Mac will not sync incoming messages but can send outbound messages.
