Server side change on YouTube's part; Apple may have asked them to do this due to the crashing.

If you dare:

Enable the Developer menu in Safari Preferences (Advanced tab)

Set the agent string to Firefox/Windows.

Then surf to your desired HDR content.

But yes, you will crash watching that sweet sweet HDR content.

Do you see the HDR icon when you use Youtube?
So I wasn’t seeing the HDR icon, and all of my videos were loading extremely slowly and buffering.

I turned off iCloud private relay and the buffering issue was gone and HDR returned. Maybe it’s a bandwidth check on YouTube’s side before serving up HDR?

Sure enough!

Yeah, I don't know. Working for me in the Firefox - Windows agent smith suggested. You can select pretty low bandwidth and should still be able to get HDR, but I don't get it in Safari.

Actually, you know it was just an assumption on my part that this is a server-side fix.

Perhaps (dons tin-foil hat) Apple pushed one of those silent s/w updates to have Safari send a different user agent string to YouTube...

Either way @arn there's an interesting story here...

Nope! Not working for me either. Just plain old boring 4K and I believe it’s on YouTube part. There wasn’t any update for macOS so makes sense it’s YT server side.

Can confirm. On my chrome Costa Rica now only says 4K. No HDR. and on the stats for nerds it's also obvious. Though it still looks awesome ?. Not a deal breaker for me tbh since i rarely see HDR in YouTube. Only when I want to show how amazing the screen is to somebody ?

Don't use Safari. I use Firefox most of the time. Love it. Use Safari off and on, but Firefox is my default browser.

This has nothing to do with Firefox... weird post. Firefox don't even have HDR support.

YouTube changed something on their end. Not the macOS, we have no updates on it. I managed to get the HDR back on my Safari with Chrome Windows agent.

Yeah definitely. They prob are disabling it for now since the stable and beta Monterey for the new MBP still crashes the laptop
Hey mate, any news If the latest beta fixes the MagSafe charging bug?

Also missing HDR playback in YouTube.

Haven't tested. Since i heard there is bugs with full screen applications with touchpad gesture if you use the show menu bar thingy. Since i need that I can't upgrade to the beta 2 just yet.

Been waiting for people on beta 2 to review it but none yet unfortunately :(

Apple has really crapped the bed lately when it comes to software.

The wait continues ? hopefully it's not hardware related, my Mac is spotless, screen is gorgeous, don't want to play the exchange lottery and end up with a cosmetic defect or crap display.

Thanks for the update.

I’ll add to this because I thought I was going crazy - was watching HDR videos this morning on the Tally Ho Tech channel then they (and other HDR content) suddenly were only available in 4K since. I'm curious if this is related at all to my previous post about the Apple TV app not streaming HDR content. And I just realized that Disney+ is also supposed to stream in HDR and it's not.

Hope you're right, what worries me, it's only a small number of us with this issue. ?

Hopefully apple support is taking it seriously.
Yeah . Here's the thing though. I wouldn't even know about this problem if I didn't check the forums lol. Since i never actually charge the laptop with it off and with it's lid closed . Especially since the bug only happens if you close it and then charge. Not charge and then shut it down and close it. Also it only happens below a certain battery percentage.

I think either people don't report it since they don't use these forums or they just don't experience it since they haven't tried it.

Most people never shutdown their Macs, I'll get in touch with apple support if it's not fixed in the next few betas.
