How To Fix MacBook Pro Crashing While Playing YouTube 4K HDR Videos
Most likely, this issue has to be fixed by Apple with a macOS Monterey software update. However, there is a workaround that you can apply until then.
Disable AV1 Codec
Apparently the MacBook Pro unexpected reboots are caused by a glitch involving the AV1 codec. To bypass the issue you have to disable it, but this can only be done in Google Chrome:
- Open Google Chrome, which you can download from Google.com (direct link).
- Next, you have to install the enhanced-h264ify Extension for Google Chrome.
- Click the Google Chrome Extensions icon available in the top-right corner, at the end of the address bar.
- Click on the enhanced-h264ify extension. Block AV1 and everything else exceptin VP9!
– Click on Chrome, available in the top-left corner of the menu bar and go for Preferences.
-> Next, click on Extensions available at the end of the left sidebar.
Now click the three-lines icon available next to Extensions, in the top-left corner of the screen.
-> Go for Open Chrome Web Store and search for the enhanced-h264ify extension. It allows you to choose what video codec YouTube should use when playing videos.
-> Click Add Extension and confirm.
Now play the 4K HDR YouTube videos. Does your 2021 MacBook Pro still crash? Use the comments section to share your feedback. Also, don’t hesitate to share a better workaround if available.
