Mac Messages Splitting Named Group Chat Into Unnamed But Same Group

Just another bit of info if it helps. Some of the chats have my own name included at the top & the bubble, the others don't. I think it's only happening with chats that have iOS & Android clients.

I'm having this issue as well. It starts a separate group chat with the same people and myself (as an additional group member) on my Macbook messages, but on my iPhone, it's working perfectly fine.

The same thing is happening to me and I know it only happened after I updated to Sonoma 14.6.1. I've had texts split between the original and fracture group chat that were sent by the same person within 30 seconds.

Same issue - it also seems to be a thing with MMS with an individual sender. When a non-iphone user sends a photo, it appears in a new "group" chat with myself appearing as a 2nd participant with the sender on my Mac. If I respond to that chat, then a new chat will appear on my phone.

Confirming with three family members today they are all having the same issue - three on MacBooks, one on an iPad. Very frustrating!

Same for me. Notably, when I view Messages on an iOS device, the conversation is NOT split in two there. All messages between participants display in the same conversation thread. I'm on Sonoma 14.6.1 and my iOS version is 17.5.1.

The other participants are on Android.

Vexing!

I'm having the same issue and sometimes in threads with only one person. I've seen the glitch on my phone, but it mostly occurs on my Macs. I've tried signing out and turning off Messages on all devices except my phone but it didn't help.

My phone re(?)-updated to iOS 17.6.1 overnight (Fri 8/30 into Sat 8/31), and when I responded to a mixed Android/iPhone group text thread through my Mac today, a new thread did not form on my phone. When I responded through my phone, everything seemed back to normal on the Mac, too. So, maybe something wasn't working between the iOS and Mac OS and has been debugged? 🤞🏼

I'm having the same exact issue. Looking forward to a fix!

I've also spent 4 hours with their tech support (so far) before the issue was escalated to the engineers. They're supposed to get back to me later this week.

Like you, I'm skeptical that this is a Verizon issue. As has been stated upthread, this only happened with the Sonoma 14.6.1 update. It would be an amazing coincidence if Verizon updated their SMS/MMS/RCS handling at the exact same time.

One more bit of info I don't think I've seen here yet. I've noticed that on my Macs when I get a notification for one of these group messages, I often see (null) rather than the person who sent the message. For instance:

(null) loved an attachment

Hoping this gets a fix soon. It's really difficult to keep track of one conversation split into two.

Same issue for me. My Mac and my iPad are suddenly splitting all text groups that contain Android users. The new text groups don’t show the group name, and show me as a member. It’s not necessarily the Android users that are getting split, however. Perhaps it’s caused by MMS texts and based on which texts I reply to.

Agree that this only happens with messages to multiple people where at least one has an Android. Spent an hour in the Apple store today with their "genius". He said it's an iCloud issue. Said support had to handle it. Contacted support (another hour), and they said their "Senior Department" has to handle it. The Senior Department told me it's a Verizon issue. I am skeptical, since it happens on an iphone (Verizon), ipad (AT&T), and two Macs.

Typical support answer. Blame the other guy, wash hands of problem. This coincided 100% with upgrading to 14.6.1. Some of the behavior I've posted in this thread is in Apple's court to fix (i.e. my name being in one of the split chats and not the other as well as the (null) identifier I see in notifications as to who sent the most recent message. They have something to fix. Group chats are part of our lives and this needs to be resolved.
