Sleep Wake Failure: Reboots only after upgrading to High Sierra

I have spent the last month dealing with the sleep wake failure ordeal.


When High Sierra was released I took the upgrade like I always do. When my iMac goes to sleep I will be in the other room and can hear my system rebooting. The startup sound plays twice. Then the apple logo appears on the screen with and progress bar (as if something were installing) Once High Sierra starts it displays a message "Your computer was restarted because of a problem. "Sleep Wake Failure"


I have contacted Apple support on several occasions with no luck.

I have unplugged the cord - removed it from the computer for 15 seconds to reset the smc

I have reset the NVRAM

I have backed up my system using time machine and used disk utility on internet recovery to erase my iMac

I have done a fresh install of Mac OS (High Sierra) with Time Machine backup and a separate time without a backup

I have started in safe mode

Mac OS High Sierra 11.0.3

Even after doing all these tasks my iMac still reboots when in sleep mode.


I have had my iMac for several years and this has never happened before. Now it cant stop happening.


Any help would be greatly appreciated.

iMac, iOS 11.0.3

Is yours with the stock SSD?


After discussions with OWC and others, it does seem like Apple has seriously mis-calculated their power management capabilities.


We resolved the issue by opening up terminal and running:


sudo pmset standby 0


This disables standby which, in most cases, kicks in at about 3 hours into sleep. This will cut a lot more power to more of the system. And this is why it has issues coming back alive after a long (+3h) sleep. You actually might still have long-boot issues when rebooting or cold booting, but at least you can not have these ridiculous wake issues.


You should be good ... Try it and see.


Apple has yet to acknowledge any of the issues anyone has with their 2012-2015 MacBook and MacBook Pros. I know multiple people that Apple has charged for replacement SSD when it is obviously an engineering flaw.

I too am on 10.13.2 and still have the issue. High Sierra upgrade did it. For me, disconnecting my 2nd monitor seems to prevent this from happening, but I prefer 2 monitors. Sent dozens of error reports to apple and no response. Not going to try the many work-arounds on this thread as it is clear that nothing apple proposed works. They are just guessing.

I appreciate the help. I tried the sudo pmset standby 0 and later that same day my iMac went into sleep mode and after doing so did a reboot.

I have contacted apple support on several occasions but this time I think I might be getting somewhere.

I am dealing with a senior manager that has copies of all of my error reports. He has sent them off to some people that understand these reports much better than I do. It's been about 2 weeks but he did get back to me the other day with a mention of progress. I will keep this group in the loop with all info received.


Hang in there people, hopefully this gets figured out in a timely manner.

Well not sure if this is a wild goose chase or not but my battery settings are different from yours. And you said it was working when attached to A/C but not when running on battery, right?


So here are my settings just in case you want to try to match them:


$ pmset -g live

System-wide power settings:

Currently in use:

standbydelay 10800

standby 0

halfdim 1

hibernatefile /var/vm/sleepimage

powernap 0

gpuswitch 2

disksleep 10

sleep 10 (sleep prevented by sharingd)

autopoweroffdelay 14400

hibernatemode 3

autopoweroff 1

ttyskeepawake 1

displaysleep 2

tcpkeepalive 1

acwake 0

lidwake 1


Perhaps the ones to look at are "standby" and ... actually, just standby.

I"ve just installed 10.13.3 in hope that Apple have addressed the sleep restart problem. I like others have installed High Sierra many times after updates and advice on this discussion. The computer woke from sleep correctly this morning but only time will tell. I've searched but cannot find what Apple have done in this latest beta release, perhaps one of you guys can tell me?

Here is my tale.


I have MacBook Pro (13-inch, 2016, Four Thunderbolt 3 Ports) purchased in early February 2017.


After multiple failures to wake which was at the end not helped by NVRAM or SMC resets I took the computer to my local Apple Store. They were unable to get the computer to function and they accepted it for repair under warranty. When I got it back they had replaced the main board, the battery and the display; basically everything. The computer came back with MacOS 10.12.6 installed. Before I reinstalled ANY of my software the computer began to show Sleep Wake Failure. I now have turned off sleep and that is how I will continue to operate so that I can salvage some of my investment in this machine.


My first Mac was a 128K Macintosh. This MacBook Pro will be my last Apple computer. As demonstrated by this support thread and my own experience, Apple has multiple software and hardware problems with its current generation Macs and it is clear that they are both unwilling and more importantly UNABLE to fix these problems.

Adding on so that maybe Apple notices how many people are having this issue and does something about it...


Mid 2015 MacBook Pro on 10.11.6.


I don't think it's an OS issue, necessarily, but a hardware one as I have a Mid 2011 MacBook Pro that has been on everything from 10.7 up to 10.12 and it does NOT have this issue. It seems to be common to 2015 models as I have googled this issue and that one seems to show up the most.


This happens about once a week fairly reliably on the same day. Why the same day? Because that's the only day I remove it from being plugged in and take it elsewhere with me. It goes from a desk where it is attached to 2 external monitors and uses a USB Ethernet adapter for internet and then to another desk where it uses the wireless (the WiFi is turned OFF when it's at the first desk and is only turned ON after I log in at the second) and does not connect to any external monitors. In transport from one desk to the other, it is asleep. It does not reboot right away. Rather, it seems to reboot randomly anywhere from a couple hours after being moved to 12 or so. Usually this happens without my having interacted with it at all during this time. Just now, after not having touched the computer since I moved it at around 4:30PM today, it rebooted itself while sitting here with the lid closed and (supposedly) asleep.


This is a continued annoyance. I would also like to note that the rest of the week, as the computer sits in the same spot and is put to sleep rather than shut down every day, it doesn't reboot.


The reasons given for the reboots each time is sleep/wake failure. The usual fixes of resetting things doesn't do it. As it's happening on different versions of macOS, I don't think it's necessarily an OS issue, especially given that my 2011 MacBook Pro is not having this problem (it has other issues which I think I can attribute to the OS that amount to the Mac version of blue screening (something it never did pre-10.10), but that's neither here nor there since it's not a "sleep/wake failure" error...)

iMac (21.5 in, Late 2012) - Sleep Wake Failure after updating to High Sierra, currently Version 10.13.3


There are 560 responses to this comment, that is since mid December 2017, reporting the same issue. I have been reporting to Apple on an almost daily basis for about a month now. There is at least one other thread, discussing the same problem. All respondents are suffering persistent, disruptive and recurrent difficulties with their apple computers rebooting unexpectedly in sleep mode.


It is disgraceful that Apple would not even acknowledge the issue. This is an appalling attitude to mostly faithful and devoted customers.


So very disappointing!
