Could this be a Regional setting? AV1 VP9 settings? Try to test the HDR Dolby link below. If those videos don't crash your mac... it's YouTube. YouTube has been changing format per account. I recently received a new YouTube design/format. Not everyone gets it.

I haven't crashed once.

Youtube crashing a whole laptop instead of just the browser? The OS should prevent that.

So you need a new M1 Pro/M1 Max, watching a HDR YouTube video, using Monterey and Safari?

I am surprised they found this bug with that combination. I love Safari but it’s lack of real ad blocking and no real cross platform support options makes it a no go for me.

Using Edge with UBlock on my 16inch M1 Pro, I do not see ads EVER or crash when watching YouTube videos.

Wow, you and Apple illustrate the exact same lack of imagination and skillful prowess required to track down bugs. You should apply for a QA position at Apple. Looks like you would fit right in, and it isn't like the Apple QA staff work very much... o_O

Yes, an OS that likely has many millions of lines of code that behaves in all potential user settings and use scenarios 100.0% perfectly, 100.0% of the time, for many millions of users.

Where can I buy such an OS?

You’re confusing customers with employees. If a company doesn’t have a system for identifying why products are being returned that’s on them not the customer.

It is on the customer. You aren’t willing to give the company time to work with you to resolve your issue, let alone you working with them for the product they are supporting. That doesn’t make it a crappy product; that shows how unwilling the customer is to wanting their problem fixed, so they wash their hands of it.

Additionally, as it sweeps the problem under the rug, when you exchange the product for a replacement, you would more than likely end up with a product that has the same problem, repeating your cycle all over again.

And what was Einstein’s definition of Insanity? Repeating the same thing over and over again, while expecting a different result?

There’s your sign; the logic you’re showing here is proving Einstein to be correct.

BL.

This is just guessing based on my dev work:

I think WebKit uses mipmaps for textures, like other graphics engines, so it’s possible that WebKit and Chromium can’t actually support 4K video.

The internet and its browsers weren’t built to display large photos, even though that’s it main purpose today.

I think the way you read video is to pass the video buffer into 8 bit chunks that represent a pixel or maybe 4 pixels. 4 pixels would make sense since video resolutions have to be divisible by 2.

Then you pass that pixel data to the GPU where many GPU threads compile a canvas or bitmap in near real-time.

The bitmap (frame image) is sent to the media player, which updates say 30 frames per second.

Netflix, Hulu and YouTube aren’t actually supposed to use browsers for internet video.

They’re supposed to establish a connection with the client and pass chunks of data (the frame image) like when you play Counter Strike online, or any FPS. You may remember this from VLC or Windows Media Player in 1998.

I think all of this stuff came about in the 90’s when the guy writing the backend also knew the front end, so they cut corners and just built everything on top of Internet Explorer.

And now if you’re a top Swift dev, Apple or Microsoft or Google wants to hire you for the OS, over Netflix, so it’s a vicious cycle if that makes sense. So Netflix is sort of stuck with web devs to make a Netflix application.

Not trying to be a troll.

Others have reported this issue on MBA M1 but knock on wood I haven't been able to replicate. Wonder if it's a conflict with Safari adblocker or extension? I don't have Safari adblocker installed on mine but do have uBlock Origin on Chrome and haven't had any issue on either browser watching 4K YouTube and scrolling comments.
 
I have tried a couple of HDR videos on my 14" MBP and couldn't reproduce this issue. All videos were 4K and were played on YouTube on Safari.

Is YouTube 4K a premium service? As in, one you pay for? This part always confuses me.

I think Apple TV, if you use Swift, it establishes a connection and buffers the data correctly.

If you use a HTTPRequest on Swift for Apple TV, it works the right way. I’ve done this, it’s not difficult. :)
 
I have a 64GB M1 Max 8TB and it absolutely crashed and rebooted my computer as soon as I scrolled through the comments while playing 4K HDR video in YouTube. The screen froze for about 5 seconds before it went black and rebooted.

UPDATE: When I play this Costa Rica video, my computer does NOT crash.

But if I play this video, it does crash:

I changed my tab setting in Safari to "compact" and the computer does not crash when running the same test again.
I thought switching to compact tabs fixed the issue but I just played an HDR video I previously didn't try and my computer crashed, using compact tab setting.

I have AdGuard for Mac, no issues what so ever and I can use any browser I want.
 
Netflix asking Apple for code is like a local pizzeria asking Papa John’s for help.

You know, the Timberwolves aren’t that great this year. Maybe LeBron can help?
