Hello. I have a 2013 Macbook Air that recently started to crash about once a week. Sometimes the screen would just go black, and sit there doing nothing. Other times, it would go black, and eventually reboot itself.
This morning, the latter happened. I was working, the screen went black, and a few minutes later, it reboots. After it reboots, I copied the crash log to a text file and tried to look for clues as to what might have caused the crash. However, I'm not very good at deciphering logs, so would love if someone could help me take a look.
The following is the contents of this morning crash log:
