Syncing Messages Across All Devices, NOT

Thanks for posting. Rarely do I search Apple Communities as see a same day, active post. Having the same problem with Mac 15.2 and iPhone 18.2.1. Tried manual sync on phone but doesn’t sync with Mac. Mac keeps pausing cloud sync. Also searched online for solutions and tried recommendations. Hope we get a fix soon.

I have this problem, also, with iMessages I send on my 18.2.1 iPad not syncing to 15.1.1 M1 Mac mini. I had a very long session 12/4/2024 online with an Apple tech expert who was very knowledgeable, ran through everything, and was positive she had solved the problem. But unfortunately the problem wasn't corrected. The Messages in iCloud window for my Mac is still stuck on 0 message In iCloud and clicking the Sync Now button does nothing.

I haven't contacted Apple support again because I've seen multiple people report it and Apple must know by now that it's a bug--I'm just waiting for them to fix it.

Me too. I have M1 iMac and iPhone 16Plus. I've had four sessions with Apple Tech including reinstalling the IMac OS, all to no avail.

I keep hoping every update will fix it. It started for me OS15 update.

Messages App stalls, won't close, won't open, won't send messages.

My wife and kids login in same IMac don't have the problem, so I was sure it's a setting somewhere but I can't find it

If anyone makes any progress, please update here

Keep not holding your breath...Slowly but surely, the promised performance of Apple devices is degrading - " ease of use has been declining at least as long.

For me, a text message I received immediately on my iPhone may not appear till the next day, creating a very misleading thread order. The main body of a text I sent on one device didn't appear for hours although shorter messages in that convo appeared in timely fashion.

And it won't really surprise me if this report never appears in Communities.

I ended up restarting all devices that sync to Messages. Which barely helped. Then with the subsequent version updates, the sync occurred and over the next few days Messages on 15pro and macbook M1 slowly “healed" and sync’d.

As of today, phone mirroring works for Messages, sync between phone and macbook works okay but doesn’t sync Send Later texts.

Agree, hope Apple has enough feedback from Community and customer support calls to finally fix syncing Messages in next macOS and iOS updates.
