I've been experiencing repeated kernel panics on my 2015 Macbook Pro. Sometimes the fans start spinning really loudly before the panic, sometimes not. Sometimes the screen jut goes black, sometimes it glitches in crazy ways (see picture).

I've taken the MacBook to a repair shop and they've looked at it four times(!), each time insisting that nothing is wrong with the hardware and that they can't replicate the error.

Here are the two latest panic logs:

  • Can you make the error happen?
    – bmike
    Feb 15 at 12:32
  • Unfortunately not! It can occur when browsing, during installation of an uppdate or whenever. Video calls and games seems to increase the likelihood of a crash but it’s never predictable

  • Bummer - and I presume the screen is perfect except when the machine crashes?
    – bmike
    Feb 16 at 19:42
  • Yes, it's only like that when it crashes, and even then only maybe 20% of the time

The repair shop got tired of me constantly coming back and decided to replace the motherboard free of charge. The computer works fine now, so it was most likely a hardware error.
