macOS Sonoma crashes when using QuickTime Player

"macOS Sonoma crashes when using QuickTime Player: 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?"

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.

"macOS Sonoma crashes when using QuickTime Player: Sorry, that went over my head. I assume you're talking about installed extensions, not filename extensions. Regardless, extensions are not changed by me.[…]”

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.

A week later now - is the problem still there? I experienced the same thing a few months ago when I also upgraded to Sonoma, I couldn't use quicktime at all without it freezing and crashing. I downgraded back to Ventura and the problem was not there anymore. The Quicktime glitch still hasn't been fixed?

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.

Hello, alexanderlindo:

I changed the Live Wallpaper to a static image and tested by clicking two .mov files. The first one played fine and then the second one froze my laptop which is an Apple M1 Pro running macOS Sonoma v14.2.1 (23C71). This change had no effect from my end.

Best,

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.

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!

Just an update, I have been using 14in Mac Pro without monitor for past few days and not experienced a crash. As soon as I connect monitor it becomes a ticking time bomb, no particular pattern but it does crash very often.

This thread is about QuickTime Player, but I don't think it is Quick Time related. Many of the crashes I had, I was using Remote Desktop into a remote server and was not even using the laptop. It also crashed on using QuickTime once and hence I landed on this forum.

Just a hunch but I think it has something to do with "click wallpaper to reveal desktop", just a hunch. I notice that this feature does not work well with external monitor. In fact, even without monitor this feature tends to make the laptop unresponsive for a moment..... QuickTime freezes, iMovie starts to show spinner etc.

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.

I have never had a Quicktime Player crash in Sonoma, and I use it extensively, and with two displays connected.

Are you using external displays using the Apple AV digital adapter?

I do not use Stage Manager, which appears to be related. Did you try turning it off, as suggested?

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!

Have you spoken to senior advisor or Apple? Any chance appt with Genius Bar could help. Genius Bar not what it used to be. They couldn’t find a solution for my issue. Had to scour internet and took 6 months to figure out.

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?
