Apple We've Got a Problem - High Sierra Shut Down Issue.....

All,

I am noticing an increasing amount of threads related to the High Sierra random shut down issue. Here is a quick synopsis of my experience so far. Given ALL of the troubleshooting below, I think this is a software issue with High Sierra and we may have to wait for future updates in the hopes that the issue is fixed. I hope this helps for those who are having this issue:

Here is what I have done so far:

1) Performed multiple SMC/PMU resets

2) Restarted my Mac in safe mode and then restarted again in normal mode

3) Restarted Mac in "recovery mode" and performed a First Aid within Disk Utility (no issues)

4) Performed two Apple diagnostic tests by restarting in diagnostic mode (no issues)

5) Installed Apple Supplemental Update and 10.13.1

6) Reinstalled High Sierra over itself with the latest installer

After doing all this, I still had the shut down issue, so I contacted Apple Support and took my Mac to the Apple Store. The Genius also ran their own hardware/diagnostic tests and did other troubleshooting. The Genius determined there were no hardware or other issues. After doing all this, Apple helped me perform an erase and install of the entire operating system and we performed a fresh install of High Sierra. I was careful to restore necessary apps from a backup without restoring all setting.......AND......STILL HAVING THE SAME ISSUE!!

Bottom line is that I think we have a software issue with the new High Sierra. There are no hardware issues with my Mac and there were absolutely no issues before the High Sierra upgrade. After performing all of the above troubleshooting, I am thinking that we might have to wait for future software updates to see if this issue is resolved. I am hoping that Apple is looking at this because there were also a few other folks at the Genius Bar with me who had similar issues on High Sierra.

I am glad to try and provide some logs or other diagnostics for Apple if this would help, but this is getting increasingly frustrating and I hope we can find a fix soon.
