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:

  • How to:
    – 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.
