macOS Sonoma crashes when using QuickTime Player

I am using an old Thunderbolt screen with my MacBook... Quicktime crashes at times... I see if I disable the extended Thunderbolt screen. I don't have crashing issues. Going to try my old Del screen lols

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.

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.

Call Apple to report this, it's still a problem for hundreds if not thousands of users and they are dragging their feet on fixing it.

In the meantime, you can switch to extended display instead of mirrored as a workaround.

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.

Checking in on macOS Sonoma 14.4.1. I and others have sent detailed bug reports to Apple regarding this serious and undeniable issue. We are still waiting for a fix. Personally I was hoping to hold out until macOS Sonoma 14.5 is released but looking at the release notes of the betas, it does not look very promising. If the issue still persists I'll have no choice but to downgrade back to macOS Ventura which came pre-installed on my M1 MacBook Air. I am not looking forward to the process of re-formatting, re-installing macOS Ventura and restoring all my files and applications but if thats what it takes to get back to a proper working machine, then thats what I'll have to do.

I am about to embark on two more projects for my client and can't believe that Apple has not addressed this. MASSIVE productivity fail. How has Apple not prioritized and included this in most recent update?! Even long term clients like mine don't allow for excuses like "I'm sorry Apple hasn't fixed this thing I've done for you for the last 3 years". They say "I'm going to find someone who can do this now".

And in this economy, my core business is gone if I can't create the video to support the actual strategy.

I am having the same problem. QuickTime and quickView are crashing. This is not only me, colleagues are facing it. I have AppleCare enterprise, how to report it?

The issue appears to be related to using an external display. Which maybe every media professional in the world uses. It's going to be annoying if it only affects screens not made by Apple.

Just checking in here to confirm that Sonoma 14.4 does not solve the issue. Mirrored mode is still unusable for QuickTime playback.

can confirm this still occurs, while macbook pro 14” 2021 is connected to external display in mirrored mode. how has this still not been fixed??

Please send reports to Apple. Maybe, if we keep endlessly reporting they will do something about it. I've been told Apple doesn't monitor this forum.

Do you know where to send these reports that they will pay attention to?

thanks for the link - I open yet another bug report...
