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
After some testing and research, the issue appears to be in how Displays are currently being handled in Sonoma while in mirrored mode. Throughout the crashes, my M1 MacBook Air was attached to an external monitor in mirrored mode. When changing this mode to extended, it has been a week now using Quicktime exclusively for video playback without crashes. Crashes do not occur when no monitor is attached to MacBook Air. If you are using your display in mirrored mode please switch to extended mode and let us know if you see any more crashes.

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.

Just because I read it in this thread: using the Apple AV adapter OR a dedicated USB-C to DisplayPort adapter doesn't make a difference. Both make the system crash. Same goes for HDMI adapters.
You are re-enforcing what I have said. On macOS Sonoma, QuickTime is having issues with mirrored display mode on Apple Silicon based MacBooks who rely on usb-c adapters for hdmi connections.
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.

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.
Ditto - I'm able to play .mp4 files in my video editor: Camtasia.
The issue seems - in my case - to be QuickTime generally rather than .mp4 files in particular.

Do you know where to send these reports that they will pay attention to?
It was mentioned already, but here it is:

Have you Changed the Extension?
Somona seems to be a bit picky when changing the extensions. MP4 is one one them that does not open at times. So, I have reported that, myself.
Sorry, that went over my head. I assume you're talking about installed extensions, not filename extensions. Regardless, extensions are not changed by me.
I don't inderstand the connection between extensions and .mp4 files. Maybe someone can elaborate, or point to a help topic I can read?

No —filename extensions are what I am talking about. And changing the extensions can damage the file, making it inoperable and never be a ale to be opened again.
Just put in the latest Sonoma after endless crashes on the 14.0. Now we are on 14.1.2 and still ****** off that I can't get through my workflow involving videos in vlc or Resolve or qt player. Can not get through a video without a system FREEZE. Pathetic that APPLE does not respond or do SOMETHING. Guess they are clueless.
I am experiencing the same with use of QuickTime and macOS Sonoma 14.2.1 (23C71). When I create a screen recording all goes well however when I review the recording my system will hang and the beachball will appear. Sometimes my computer will reboot on its own saying an issue occurred and other times I have to complete a force reboot. I did not experience any issues with use of QuickTime when my laptop was on macOS Ventura.
Wow, I'm surprised. I'm using Big Sur which is older and just used it yesterday without issue. Hope they fix it soon for you and other in Sonoma. I see many others are having same issue. I use this app all the time.
Only thing I can think of is that they’ll say they don’t support vintage. Of others are having the same issue with supported newer devices they would act on it. Not to say you would see a fix anytime soon. I love quick time but just use it for recording.
