Messages between Mac & iPhone not syncing after upgrade to MacOS Sonoma 14.4 & iOS 17.4

RE: >On your iPhone, go to Settings -> <your icon at the top> -> iCloud -> Show All<

Where do you see "Show All"? Doesn't appear on my iPhone, iOS 17.4.1.

I never had a problem until I upgraded this Macbook Pro last night to Sonoma 14.4.1. Now I see texts on my phone that don't appear in Messages on this screen.

Hope someone can help. I do nearly half my messaging from this laptop. Thanks.

Please fix this problem.Since I updated to Sonoma 14.4.1 I have to constantly restart my computer so that iMessage on my iPhone 11 Pro sync with my iMac book pro. Please please fix this as soon as possible.

Here's what's been working for me:

• On your iPhone, go to Settings -> <your icon at the top> -> iCloud -> Show All -> Messages in iCloud -> Sync Now
• (Once it's done syncing, note how many messages it says are in iCloud.)
• On your Mac, go to System Settings -> <your icon at the top> -> iCloud -> Show More Apps -> Messages in iCloud -> Sync Now
• If your MacBook still shows messages that your iPhone doesn't, you may need to repeat the steps one more time. The message counts the two devices think are in iCloud should match by the end. I still have one or two messages on my phone that never reached my Mac (or iCloud, presumably), but everything else shows up for me on both devices and the counts agree.

Doing this, sometimes multiple times a day, is a pain, as is unknowingly missing messages, so I hope Apple fixes the problem soon.

I finally upgraded my MacBook Pro from Monterey to Sonoma 14.4.1 a week ago (May 8, 2024) and have experienced this behavior of messages not syncing with my iPhone 13 (running 17.4.1) enough times that I felt the need to check the Apple Community for help. Probably 80% of my texting is done from my iPhone, but on occasions when I open my laptop to respond to a GREEN text message string that appeared on my iPhone, it was not on my laptop. This problem seems to occur mostly with GREEN text messages, although I have also experienced a delayed sync with BLUE iMessages. Prior to Sonoma 14.4.1, all messages synced seamlessly. As others have mentioned, my only resolution has also been restarting my Mac when this happens...which is a major pain. Just wanted to throw in my 2 cents with hopes that Apple will address this obvious BUG with Sonoma 14.4.1...PLEASE AND THANK YOU.

Sorry, for me the "Apps Using iCloud" section on the iCloud screen shows a partial list, and I have to select "Show All" at the bottom of it to see the rest of the apps, but if your list isn't that long then "Messages in iCloud" is probably shown already and you can just select it. Same with "Show More Apps" on the laptop.

Wow, now I'm afraid to upgrade to 14.4.1. Although maybe the problem isn't actually tied to a particular version but is rather a flaw in the combined upgrade process in general? I've seen posts complaining about it with 14.0, while it only started for me with 14.4. Anyway, good luck (to all of us)!

Did anyone ever find a fix for this?

I cannot consistently send Messages from my MacBook Air (15" M2 2023 OS 14.4). There are two people (one with an iPhone, the other with an Android) that I can usually send to, but on occasion I get Message Not Sent notices and I can't seem to do anything about it. Those messages don't sync to my iPhone (ancient 2nd gen SE but iOS 17.4) either. I can send to those people consistently from my iPhone.

Update: this resolved for me with iOS 17.4.1. Since I had the problem both before and after installing iOS 17.4, I'd assumed the cause was the change to Sonoma 14.4, but I've now seen posts about it happening with other combinations of MacOS and iOS, so I guess it's just a tricky thing for Apple to solve for all cases.

My messages are now syncing with the latest updates to both iPhone and Sonoma BUT the messages I've read on my iPhone (iOS 17.4) are not showing as read on my Mac (Sonoma 14.4). Does anyone else see this and have a solution? Syncing messages on iPhone and Mac does not fix this
