How to fix Messages app closing after macOS Sequoia 15.4 update?

You're experiencing a different problem than this forum thread is discussing - sounds like something user account-related. You might want to investigate clearing caches for Messages and FaceTime.

This has been happening to me since the 15.4 update on an Air M2. No crash message, nothing in Console logs. Just... closed. It seems random. Might be 10 mins, might be 2 hours, but it will happen. I've safe-booted, and used Cocktail to clear all of the caches (then another reboot) as well. Never seen this behavior before. I should note it is NOT occurring on an M4 MBP, also at 15.4. Very frustrating.

I just noticed the same problem. I also had the stocks app close itself.

I think this may be a memory pressure issue as I noticed my Mac's memory pressure was yellow even though I wasn't really doing anything at the time. My M1 MBA only has 8 GB of RAM.

Same here. M1 Studio and an M4 MBP. Messages app, Stocks app, Carrot Weather, others. No notification, just the fact the apps have closed/crashed and aren't running. 15.4 introduced this issue. Hopefully a fix is forthcoming.

I've clicked the "Me too" button but also wanted to add that I doubt it's memory pressure. I have 16GB of RAM and 1TB SSD on a 15inch M2 MacBook Air and only the Messages app is disappearing (which didn't happen prior to 15.4). In my case it seems to happen while I'm not using the computer (eg. it's always gone after the screen locks and I return).

Installed 15.4.1 last night on my M2 Pro Mac mini and Messages stayed up all night ... was ready to declare success but after a morning of a couple messages, the app silently closed again! So for me, issue has NOT been fixed. Note that I also had couple other apps silently closing, Find My and Podcast, and I'm expecting those will still be exhibiting the same bad behavior after this latest update. Very frustrating! I did report this via Feedback Assistant and will update again.

Yes, installed 15.4.1 and apps are still randomly and silently closing, including Messages, Find My, Podcasts, News, etc. Also tried booting into Safe Mode to clear caches and even reinstalled 15.4.1 in Recovery mode, nothing has helped. I did report via Feedback Assistant, fwiw.

As I've been assessing this bug Apple introduced with MacOS 15.4, I'm noticing that whenever a new message is received, it crashes/closes the Messages app on my Mac Studio M1.

I just spoke to them about this and allegedly it will be fixed in the next update as they have enough error logs to know why it is happening.

This just started happening to me, currently on macOS 15.4.1. Updating to 15.5 now and hopefully it goes away.

This is happening to me too. I updated my Mac Mini M1 to 15.4. Random shutdowns of only Apple applications (Weather, Stocks, Messages, News) multiple times a day. No error messages just random shut downs. Have rebooted a few times.

I also started seeing this after the 15.4 update. So far I have only noticed it in the Messages app, but I do not consistently run any of the other apps that have been mentioned in this thread so far. Today, I saw odd behavior from Apple Music app (song would start, get to 1 second, and start over, in a never-ending loop), but I don't think that is related and just started today, while the Messages quitting issue has been ever since the 15.4 update.

I have also found that clicking a completely random link in Safari will cause it to crash, with the "Safari Crashed" dialog box. Before 15.4 I can't recall Safari EVER crashing for any reason on Sequoia or earlier. I did check memory pressure and it's fine. 15.4 is a bodged update for sure. And Messages is still crashing as before- no change.

I'm experiencing the same issue as everyone else. I don't really use Apple apps, but it is happening many times each day with both Textual IRC and Mimestream. This is on a 2020 Intel MacBook Air, so it's not only limited to Apple silicon.

And now, because the fun never ends with the BS that is 15.4, Safari just crashed when I clicked on a YouTube link. Poof- gone. I had about 20 windows open, and Safari is set to reopen all windows from the last session, but of course when Safari relaunched ***NONE*** of my previous windows reopened. Great. Thanks so much Apple. This is the WORST, most BODGED update Apple has put out in many, many years. FIX IT APPLE. I am sick of wasting my time with Messages and Safari!!!!!!!!!!!!!!!!!!!!!!
