Upgraded to macOS Sonoma a couple days ago.
Crashed 4x in the last two days when using QuickTime Player, 2x when using it to record video, 2x when using it to play .mp4 files. On each occasion a report was forwarded to Apple.
Any known fixes?
MacBook Pro 13″, OS X 10.11
I switched over to Elmedia Player https://www.elmedia-video-player.com/ and things seem to be working ok. There's a free version and a paid version . . . and here's a site that will show you how to change Elmedia to your default video file viewer: https://recorder.easeus.com/screen-recording-resource/change-default-video-player-mac.html
Just tried this fix and so far it's working! Was able to grab screen shots from 12 QT videos very quickly and easily after this fix and thus far total screen freeze/crashing. Fingers crossed! Thank you!
I am having this same issue. Terrible crashes both with intentionally running QuickTime and with unintentionally setting off the mini "preview play" feature they now offer when you click on icons on the desktop and in folders, for video files. Very frustrating, requires full restart.
I run a second monitor in mirror mode, which a lot of graphic designers do.
I've just "solved" it by installing VLC player and setting everything to open automatically in that. I'm sure this solution won't work for those reliant on special QuickTime features, but I'm too tired of waiting literal months while Apple solves it.
Sonoma 14.4 is out, and some people have reported it fixed this problem. It's worth a try.
Also, this problem does not seem to occur when extending desktop - which would seem a much more practical way to use that screen real estate...
This is not a hardware issue, it is a software issue in macOS Sonoma.
Most video files crash QuickTime while in Mirrored mode on macOS Sonoma.
The only options until Apple fixes the issue are:
1) to not use your machine in Mirrored mode
2) Use a third party video player
3) Downgrade to macOS Ventura
This! I'm in a position now where I'm facing the same discussion with Apple. Had an initial call, guy on the line told me that I need to do a lot of tests, reinstall the OS, or format the whole Mac if a reinstall doesn't work, otherwise he is not allowed to reach out to the devs. I'm reluctant to go further, especially after reading this.
Truth be told: people do use external screens. They do use mirroring. It's hard to believe that nobody in the Apple dev team does that.

I understand how frustrating this is, it's fair to say that for those affected this is a very serious issues.
The problem, however, is harder to pin down than a "bug in Sonoma"... many users do NOT see this problem, even when using mirrored screens. I have tested this on all of my macs (Intel and Apple Silicon), as well as those of a few friends, all running Sonoma. I could NOT reproduce this problem, despite using a plethora of different macs and displays.

It is good to know that you are not experiencing this issue, I wish I could say the same. What is your current setup? I am using an M1 MacBook Air connected to an external Samsung monitor via the official Apple Multiport USB-C AV Adapter.
My working machine is a 2019 16" MBP (Intel). I am using it with different HDMI displays, in mirror or extended desktop mode. What I don't have is the Apple Multiport USB-C AV Adapter; I don't have access to one of those to test, I have used different USB-C to HDMI adapters and also USB-C docks that have an HDMI port.
I have also tested this it with an M1 Max Mac Studio, and could not make the problem happen.
It seems that the Apple AV adapter may be a big part of the problem.

Indeed, you'd be correct, Your MacBook Pro is Intel-based and your M1 Max Mac Studio does not rely on usb adapters for hdmi connections. So that would narrow the issue down to QuickTime having issues with mirrored display mode on Apple Silicon based MacBooks who rely on usb-c adapters for hdmi connections.
OP here, this issue may be resolved. It was reported above that the problems with playing mp4 files might be connected to using an external monitor.
Last night I upgraded to Sonoma 14.4. This morning I disconnected my external monitor and played a 20-minute mp4 file w/o problems. This is hardly conclusive ... but the hint is to do this: 1. upgrade your OS, and 2. disconnect your external monitor.
I see this issue as well. M1 Max MBP, Sonoma 14.4.1 , 2 external 4k displays via OWC Thunderbolt mini dock I have the built-in display mirroring one of the extended displays, with the laptop "mostly" closed.

Apple is not here. This is a user forum, we are users just like you.
And although I understand the frustration, this Quicktime problem is only affecting some users. This makes it harder to troubleshoot. Do please send detailed feedback about the problem. FWIW, in either intel or m1 macs I’ve tried, using external displays, mirrored or not, I have never seen the present problem occur.
When I use quicktime to play a short mp4 that works in many other plays, quicktime freeze almost 100% of the time leading a soft-reboot (login out of the user).
I have sent crash report multiple times but this has been there for a long time.
Playing a mp4 clip is such a common activity and both quicktime and Mac are made by Apple, but we are still experiencing something one would do in the 90s.
Apple, no matter what's the root cause, you need to upgrade to being a software company!
M1 with MacOS 14.2.1 (23C71).
Just updated to Sonoma 14.5, system still freezes up when watching videos on Quicktime. External display interface becomes incredibly slow and the M1 Pro 14" laptop screen stays frozen. The crash happens the moment the cursor leaves the video area with a click. This is getting ridiculous.
My laptop froze and crashed when viewing a .MP4 that an employee sent me so I could troubleshoot her issue. I am currently running macOS Sonoma v14.4.1. When I logged back into my laptop, the .MP4 opened up and my screen would pause then flicker as if it was attempting to do something and had to complete a hard power cycle. I was finally able to login without issue and immediately closed QuickTime Player. I currently use an external monitor along with the built-in LCD.
Please provide an update when Apple will address this issue.
