<-- Early 2020 Intel MacBook Air i5 owner complains of a shrieking fan, excessive heat, and poor battery life when playing 1440 or 2160 HD YouTube videos. SAD!

So possibly the system unmaps the texture that the video is rendering into, and on next frame it's writing to nothing and triggers an unexpected interrupt.It happens the very moment the video leaves the blurred area behind the menu bar when the last horizontal line of the video disappears.
Scrolling in the comments has nothing to do with it.![]()
I was watching the straight pool video in post #17 of this thread:Can you please let us know the steps so we can try to reproduce it?
For me, this consistently causes the crash exactly as you stated, right when the bottom of the video passes "under" the semi-transparent Safari toolbar. HOWEVER, this consistency occurs only when I'm in separate tab mode. When I switch to compact mode, it does not crash most of the time. Can you try it with yours in compact mode? Just curious.After testing 10 machines (14 and 16 inch) only a single one did not crash.
The issue has nothing to do with scrolling the comments section. It happens under these circumstances:
How to reproduce the CPU panic consistently within seconds
* This also happens in Google Chrome 95.0.4638.69 (Official Build) (arm64). (Thanks @UncleGuido)
- In Safari* open any YouTube 8K HDR video.
- Select Settings/Quality/2160p60 HDR.
- Start playing the video. You may pause it.
- With the trackpad scroll down slowly. As soon as the video leaves Safari's blurry area behind the toolbar your MacBook Pro may crash. This is the critical part.

another example of the benefits of a true symbiosis of hardware and softwareCan we blame the notch?
Apple: We are desperate for a new MacOS Monterey software update.
Please fix this issue and the 120hz in safari. The ProMotion in Safari isn’t working. Why is it not being offered in Safari?
Thanks for testing Safari with a different tab layout. And yes, it does crash for me with both layouts.For me, this consistently causes the crash exactly as you stated, right when the bottom of the video passes "under" the semi-transparent Safari toolbar. HOWEVER, this consistency occurs only when I'm in separate tab mode. When I switch to compact mode, it does not crash most of the time. Can you try it with yours in compact mode? Just curious.
Not hyperbolic at all. ?Again, Apple cutting corners - sounds like the new systems are garbage. My 2015 MacBook Pro plays YouTube with no issues !
Did you experience any abnormalities when moving the video to the top just outside the semi-translucent menu bar?Tried to replicate too, and couldn't. As for the machine stuttering, I won't call it that. The scrolling seems to pause when you reach the end of the current comments list, while more comments are loaded.
Thanks for letting us know. Did it crash before upgrading to the beta?Upgraded to 12.1 beta
No crashing
Thanks for pointing that out -- in System Preferences > Displays the Refresh Rate must be set to "ProMotion" in order to reproduce the crash. I will update my posts.I felt like I was missing out too, so just tried to replicate the bug on my Monterey intel 16” MBP. Even though my display is only 60hz (like every other M1 MBP in safari it seems), hard as I might try I just couldn’t. At least my whole house is warm now ? Guess it just works.
Latest update, 08NOV2021.YEs, that is worthwhile trying and since I posted earlier I've also replicated the problem in SAFE MODE, but a Revive/Restore to replace everything directly is a good idea and I'll report back after trying. Thx for the input![]()

From what I have read and seen it the crash can be triggered by scrolling in the comments.It appears that the issue happens when scrolling in comments - is the video off-screen when this happens? If so, does it happen quickly after the video leaves the screen?
Can you confirm that you have ProMotion turned on in System Preferences/Displays?watched this one:
using above steps - ABSOLUTELY zero crashing nor anything out of the ordinary. speed scrolling, full screen, theatre mode, default modes, for the video did not crash. I don't know but you guys might have some faulty hardware if this is the case.
This is some good feedback right here as not everyone may do a restore due to a missing second Mac.Latest update, 08NOV2021.
NO CHANGE in crash behavior after Apple Configurator 2 DFU FW/OS RESTORE (did not try Revive first, went straight to full restore)... machine still crashes/kernel panics... decided to run the APPLE DIAGNOSTICSafter all of this and code ADP000, no fault found... so, I'm open to other suggestions as I really don't want to wait until Christmas to get a replacement machine if I can avoid it, but it's difficult to determine if this is a HW issue or a fixable FW/SW issue, with the variability in machine configs and the low reported problem rate, it's just not clear. Thankfully, my M1 MBA is rock solid, but this new MBP 14inch?????
chuckle chuckle, that's certainly what I was hoping for, but alas.... however on the plus side, I still have 11 days left in my 14day return window, so I'm keeping it and playing with it for the next ~6days in the hope something gets "fixed". Its a significant improvement on my M1 MBA and fun to use, but I'm not installing anything on it as I expect it's going back to Shanghai and I don't want to use an APP license on a suspect machine. Thx for your response and I'm open to more suggestions/trials....This is some good feedback right here as not everyone may do a restore due to a missing second Mac.
Too bad it didn't solve the issue. It may have been a somewhat easy fix.
Yeah, my guess is that there is a race condition in the drivers where they may not disable video rendering in time for the buffer to get reaped (since it went off-screen).From what I have read and seen it the crash can be triggered by scrolling in the comments.
The easiest and most consistent way of triggering the crash is to slowly move the playing/pausing HDR video at the full 2160p 60fps resolution up just under Safari's semi-translucent menu bar. once its not visible anymore the MacBook Pro MAY crash.
It may also happen while scrolling in the comment, but to be honest, the mindless scrolling doesn't seem like something I would do.![]()
Make sure to set your display to ProMotion (120 Hz), open an 8K HDR video in YouTube and set the video resolution to 2160p60 HDR while in the browser window and scroll _slowly_ upwards so the video will disappear under Safari's menu bar and then some more.MBP 16", M1 Pro w 16GB RAM, I'm playing HDR videos in Chrome and Safari but can't get it to crash. Can anyone share a link that's definitely a kernel killer?
