I have confirmed that this works, although I did not try with previous versions. My machine is a basic system running High Sierra, version 10.13. After lots of reading, I finally was able to come up with a solution that worked, one that did not require opening up the laptop, or installing Linux.

The AMD GPU seemed to be the most likely culprit. After some online research, I soon found out about all the issues that have plagued this machine. I did notice that if I started up the machine, but did not login to a user account, it would stay running for quite awhile. I could not find anything that was causing it, it would just be running fine, and then reboot. #Macbook air not detecting external display gfxcardstatus proBecause of this, I never was aware of the issue that thousands of other MacBook Pro owners experienced, a failing GPU causes the machine to either not work at all, have odd display effects, or reboot when video modes are switched.Ībout a year after using this machine as my main media server, it started to randomly reboot.
