The Macbook first freezes and after that the fans wil blow on max speed for a very short time followed by a black screen. The Macbook shows a popup at reboot with the error as stated above.


The device is a MacBook Pro 16" 2019 2,6 GHz 6-Core Intel Core i7.


What can I do to solve this error? I already ran a diagnostic mode (by pushing the 'D' while booting).

Have a similar issue. Happens to me when I plug/unplug my Thunderbolt dock.


Doesn't always happen, but seems to be a similar pattern.


  • Plug in to dock
  • Monitor works fine, peripherals don't
  • Unplug from dock
  • Plug back in
  • Fans spin up real quick, system restarts


Only things I have connected to the docker are a set of headphones, ethernet, and my monitor.
