macOS Sonoma crashes when using QuickTime Player

I spent all night recording a video then providing necessary edits. It worked fine until BOOM crash 1 started. QuickTime reopened successfully and luckily didn't lose much of my editing. Boom happened again...then again...then again....and NOW QT will not reopen and immediately **** down. Before I was getting crash reports but now it just opens for one second and crashes. WTF!?! I need this content for my work and can only access it via thumbnail but cannot open in QT, nor can I open ANYTHING in QT...Need a fix ASAFP!

Pretty much same issue. Not sure what device you are using but mine is 14" pro, less than 12 months old. Since, update to Sonoma , it has frozen and rebooted 10+ times, never before that, never had to reboot Mac in past.

A few comments below someone mentioned about this happening with external monitor connected on mirror mode. Could you please let us (co-sufferers) know if you are using external monitor while this is happening.

Clearly, Apple has no interest to fix this, the users will have to figure this out on their own.

It's February 5th and no sign I can see of a fix for this issue. It was bad enough losing Quick Time Pro, but so it goes. The price of progress. This is not progress. Not being able to use Quicktime is a serious disability. Some of us have to work.

Same issue on my 2020 M1 MacBook Pro. The Mac has been running flawlessly before I upgraded to Sonoma, now when doing anything with QT Player for a shorter or longer amount of time the system hangs or freezes and then the Mac reboots after a while. Very annoying as my job requires heavy use of QT Player.

So I ran the update to Sonoma 14.3.1 in the hopes that would fix the bug with Quicktime that keeps making my Macbook Pro 2020 crash when watching a video. It didn't work. I tried watching the video with VLC and it also crashes. I'm a bit at wit's end, fed up with Apple, and I need a solution in next 48 hours. I need to be able to run a video slideshow from my Macbook connected to a projector. Any ideas? Thanks!

No issue with phone. Do you know if Apple has sent this issue to engineers? If not, I’d try to get this issue to engineers.

It was a crazy situation. Apple would blame it on my iPhone case, cell provider. Even replaced phone under AppleCare. Lots of other people were having same issue. Had to do with “mic mode” setting when talking on speaker phone.

You seem to be replying to the wrong thread here. What does this have to do with Quicktime Player on the Mac?

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!

This is getting ridiculous. I don't care why this issue happens and what workarounds there are. I'm an Apple user since 1993 and I don't have the time or nerve to worry about issues like this. Please spare me "did you already do this and that…". Yes I did. 

QT Player freezes the whole system and it has been reproduced often enough. I'm working 8-10 hours a day in Final Cut and for clients expecting me to deliver in time and it's just plain embarrassing that QT isn't even able to play videos anymore. And by the way QuickLook in fullscreen also freezes the system — epic!!

I paid a lot of money and I expect nothing less than a working system.

PS: Thanks, Apple, for deleting my original post. Just shows how much you care ♥️

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 am outraged how apple is handling this bug.

It was reported in November. Had several crashes. Apple support contacted me around Christmas. Later beggining of January I have provided everything - sys logs, logs while it crashed, video taken with my iPhone while crashing and the video file that caused the crashed.

We had about 5-7 calls some about an hour long. I couldn't use my laptop (m1 Mac 13 inch) for work anymore because of the crashes and purchased another one.

Now it is mid of March and still I didn't get update what happened and if it is resolved. I am afraid to try my new machine with the mirror mode again as it is my working machine.

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.

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.

Hey Apple, this is it for me. I'm done. I'm using Macs since 1994 and been lovin' most of the stuff you did.

And now I'll be changing to another OS asap as I just cannot take this *** anymore. I will also never ever recommend a Mac to anyone I know, not with this attitude of yours towards pro users.

Sell your iPhones, sell your Apple Watches and make the consumer happy — I wish you the best of luck.

QT Player still ripping down my whole system if I'm not vigilant enough to NOT open QT player by accident. If I'm not quick enough, the whole system is down after a couple of seconds, all unsaved work is lost.

This is a mess.

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.
