Sleep Wake Failure: Reboots only after upgrading to High Sierra

I found that having "power nap" set on seemed to be the heart of my sleep-reboot issue. I didn't have the problem under HS until I turned power nap on and the problem ended when I turned power nap back off.

I had never had any issues like this until I upgraded to High Sierra and then it was persistent.

Somewhere, I saw a reference to the possibility that it could be related to VPN software, which struck a chord because I had just recently installed Cisco's AnyConnect Secure Mobility Client. So I uninstalled that app, and the issue went away. Then I reinstalled the app, expecting the issue to return, but it has not returned and it's been 2 or 3 weeks.

I suspect that won't help the majority of users, but I thought I'd share it in case it helps a few.

Tried the "sudo pmset standby 0" fix mentioned in this thread.

Worked Flawlessly! Its been a couple weeks with no more crashes!

Hello Tom,

Could you, please, check if your Power Nap (PN) option in the Energy Saver settings panel has been enabled. In a parallel thread at:

Sleep Wake Failure with High Sierra 10.13.2

there has been a discussion which suggests that with PN enabled the computer, may not go to sleep at all, which may appear as not spontaneous reboots and Sleep Wake Failures (SWF).

I would be more than happy if it turns out that the SWF problem has been resolved for good in your computer, but it might help others to know if there could be any link with the PN setting.

Thank you.

So at the end the last 10.13.2 update solved the issue - MacBook 12 is running since 3 days without restarting...

Hi,

Turning off FileVault which decrypted info and disabling certain energy settings feature were the two things that fixed it this way

One week ago I disabled automatic copy of TimeMachine and I have had no more reboots.

Everything works more than fine now on my iMac mid 2010 with OWC ssd and OSX 10.13.4

Not clear whether Apple Cares or not but it does appear Apple is not moving very fast to fix the problem.

Since I have an iMac I have decided to not use sleep, set up this up in energy saver by saying sleep never.

The screen and the hard disk will still power down but the computer will not sleep so it always comes up immediately.

I am told by a friend who does this for other reasons that the power consumption is very low in this mode and I believe it.

Today I was at the Apple Store in Hamburg. One of the "Geniuses" said, they knew about the problem of the SWF after updating to High Sierra. He also said, it should be fixed with the next macOS-Update. I hope thats true. They told me that the Update to HS could not be the reason for the sudden death of ma SSD. A coincidence?

You can downgrade to normal Sierra here:

Hopefully that will fix it for now

Hi all -- I have had this problem too for months. Don't want to raise false hope, but I upgraded to 10.13.3 yesterday and it hasn't happened since. Based on my past experience, I would have expected to see it by now. Anyway -- may be worth giving the update a try. May the force be with us!

This seems to work with my early 2014 mac book air with a 3rd party owc 1tb aura pro x ssd drive.

My guess, as has been espoused in this forum, is that if the machine sleeps, when it wakes back up, it takes too long for the 3rd party drive to initialize, and a watchdog goes ahead and reboots the machine - twice!

It is restarting because the 1tb is NOT plugged in. I believe it is the time of the night that it backs everything up and if it is not plugged in it searches for it and then does the reboots. I am going to leave it plugged in this evening and see if that solves the problem.

Since Apple does not care about the problem and I need a system that works, I decided to downgrade to Sierra. Thanks Apple! 😠

Try turning off time machine and see if it still happens. If it doesn't then you know your SSD is creating some problem, maybe draws more current then allowed?
