iMessage splitting group conversations into multiple threads

This is what's been happening to me (also within the month of Dec. 2024) -- I have a "Fam" chat, all iphones, and for some reason my messages suddenly started making a new chat to my other family members. When I'm on my phone, I only see the one chat within Messages, but when text notifications come in it does show the two separate chats (one with the Fam name, one with no name just all the group members). These two separate groups also show up on my Mac. My sister is getting very frustrated with me but I have no way to make this stop happening lol, because all my messages are being sent from my phone where it looks like it's all the same chat!

I will try the re-naming the new branch on my computer to the same name as the regular Fam group like another user mentioned earlier this month, and hope that fixes things *fingers crossed*

I'm also experiencing the same issue. Started several weeks ago.

Same here, but the splits occur also on iphone and ipad in addtion to mac.

I just updated to Sonoma and this is happening with me. I do not have Verizon, and this happens in group texts where none of the members has Verizon. So, not a Verizon or even a carrier issue.

Same here. on Mac and iOS/Pad devices. Started after sonoma 14.6.1. Other group members (one iphone and one android) do not see the problem. The iPhone user does not have a Mac, just ipad and iphone, so maybe this is why he is not seeing a problem.

Me too. And very recently. Have an iPhone 11 with iOS 17.6.1 and no other devices. Using Verizon phone, no internet. Have had many group threads with mixed apple and android friends. I’ve had an active thread since 2021 that just last week split (11/2024). Very annoying considering nothing has changed on my end. Looking for the fix

I'm having the same issue on a Mac Studio with an M2 ever since I updated to 14.6.1

I’ve seen split threads on the iPhone as well — but only after I’ve replied to them on my Mac. My workaround for the time being is to not use Messages on macOS until this gets sorted out.

Well, the problem is still on ipad and mac. All of my messages get placed on the normal 2-person thread, and mine get placed on the 3-person thread that has my name added. Ugh.

Mine also resolved. I have Verizon

Thanks again for doing the hard work of calling Apple and Verizon.

Is this happening with android users or iPhone user only also. What are the colors that show up after the message is sent(blue or green) there is a Issue that might be the cause did you speak with a T2 advisor /senior advisor ? also is this only happening when in groups

I have Verizon, mine has always been fine on my phone, but nothing is resolved on my MacBook. I still can’t use group texts that have an android user, they are still split apart. I have to use my iPhone to read/respond. This is really annoying and I wish I never updated my MacBook OS.

Same problem here, and MacOS has now updated to 14.7.

This is a major annoyance given how much critical communication is now in txts. I can understand a bug being introduced with an OS update, but not fixing that bug at the next point upgrade is Not OK! @applesupport
