QuickTime Player crashes my MacBook Pro M1 2020 Sonoma 14.1.1

Hi,

I made several tests.

I checked my videos (first one 1280*720, second one 1920*1980 and third one 3840*2160). I can screen the three in my finder window and in iMovie. I downloaded VLC software and I can screen the three videos. So I consider that my videos are correct.

I removed Cyberghost VPN from the starting softwares on my two users (Standard and administrator ones).

I tried to see my processor activity during the QuickTime screening, but when the computer freezes, Activity Monitor freezes too.

I started my computer in safe mode, I checked I was really in safe mode, but moving rapidly several times the cursor on and off the window, I succeeded in freezing my computer.

I am going to try P. Philipps idea.

Thanks

Hi,

I've got back my old IIYAMA ProLine (best definition 1920*1080), so I made some tests.

First, I used a RS-232 cable to connect the IIYAMA monitor to the MacBook Pro M1, and just by watching the first APPLE 4K film shot by my iPhone 14, the computer locked before the end of the 30 seconds video.

Second, after restarting the computer, I used a HDMI cable to connect the IIYAMA monitor to the MacBook Pro M1, and just watching another APPLE 4K film shot by My iPhone, the computer locked few seconds after the launch.

The IIYAMA monitor makes poorer results than the PHILIPS (best definition 1920*1200 and only RS-232 plug available).

For the system parameters, I use the monitor as a copy of the Macbook and as a main screen optimized by the computer.

I need to add that before the upgrade to Sonoma, every video shot with my several iPhones (5, 6+, 7+, X, 12 and 14) was watched successfully on my MacBook Pro M1.

I changed my old 2012 MacBook Pro to the MackBook Pro M1 in 2020, because the old one was not enough powerful to display films shot by the iPhone 12 Pro Max in APPLE 4K format.

I can't afford to buy an APPLE Studio Display, and I wonder what kind of monitor I need to buy, to be sure that my films shot by iPhone, will be able to be watched on my computer.

Thanks

Hi,

Unfortunatly, Mac OS 14.2.1 didn't fix my issue.

I watched correctly three videos and the fourth one locked my computer, as usual the keyboard and the keypad don't respond, the video is frozen, but the sound is still there like everything was all right.

I forgot to talk about the tests I made with my adapter.

I watch my videos, always films shot by an iPhone (14 Pro Max : mine, and 12 Pro Max : my wife's one) in APPLE 4K 24 ips (alternative current frequency is 50 Hz here but I don't know if it is still on purpose).

When the monitor is in use I have, sooner or later, an issue.

When I switch the monitor off, and the monitor is plugged in the adapter, an issue occurs too.

When I unplug the monitor from the adapter, everything is OK.

When I unplug the adapter, everything is ok.

According to these tests I consider my adapter as not guilty.

Thanks

Hi,

There are few stuffs on my computer because I only use it to make family videos using films of my grand children that I take with my IPhone. Before upgrading to Sonoma everything was OK.

I don't use Cyberghost very often on my computer, but I need it a lot on my iPad, as I live in Absurdistan (which was called France a long time ago), and rumble.com, RussiaToday.com and others are forbidden here. I don't eat west propaganda so I want to taste east propaganda.

The issue appears on each video I tried to screen on my computer, but I only get iPhone 13 and iPhone 14 shot videos. I can't test with other video because I haven't any. I will try to download one from the net, but I don't know where I can find one.

I'm a bit scary to destroy my computer with "high use of processor" that can generate high temperature.

I don't know what is the Safe Mode. Is it on Mac OS or on QuickTime Player.

I have had other issues since the upgrading to Sonoma, when I load my videos from my iPhone to my Macbook with a USB wire, using File Transfert, after several loads the transfert stops and the software disconnects my iPhone from the Finder window. If I try to unplug an replug, my iPhone is not available in the Finder window. Shutting down File Transfert and reopening it doesn't change anything. So I load my videos with airdrop but it is longer and need more checks.

I think I will try to contact APPLE. I thought I was not alone to have this kind of issue because I read users who gets similar issues on QuickTime after the upgrade of Ventura to Sonoma.

Thanks

Hi,

I stopped using QuickTime Player waiting for an exchange with my second external monitor, a IIYAMA, that I borrowed to my daughter, but I need to pick it up.

However, according to your post, it seems that my problem may not be surely fixed, it worked but I can't be sure it will always work with an external monitor.

I don't watch any web TV neither on app nor on web browser, I don't watch Youtube or other stuff like this on my computer, so I can't tell you.

But I will make tests with this monitor watching my own APPLE 4K films, created from iPhone 14 videos, with iMovie exporting it as high quality level (5 mn video weights almost 17 Go).

Thanks.

Hi,

Sure, I know RS-232 since a long time ago, around 1986.

I worked on Intel 8088, then 8086, 80286, 80386 SX then DX, 80486 and Pentium, with MS-DOS and DR-DOS, then Windows.

I switched on APPLE with the iMac G3, not for its design, but for its benchmark compared to Intel processors.

I told you that my screens were old, the IIYAMA has two plugs (HDMI and RS-232) and the PHILIPS has two plugs too (DVI and RS-232).

But I didn't update to 14.2.1, so it's a very good point, and I'm going to do it right now.

Thanks

Hi,

The adapter I use to connect my Mac is a UGREEN USB-C Multifunction Adapter (RJ45, VGA, HDMI, USB 3.0 * 3, Jack 3,5, Micro-SD, SD and USB-C), but I'm not found of it. When I plug my three USB external Hard Drive at the same time, everything is OK, but when I unplug one of them and I plug another one, one of the two others unmounts itself telling me that it has been abnormally unplugged. I can suppose a lot of stuffs but I'm not sure of any of these.

I will come back when I have tested new videos.

Thanks

Hi,

I send you the two Etrecheck and the Apple reports.

Thanks
