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.

Same thing going on here. In my case, I have a MacBook Pro late-2013 15" with Retina. Recently upgraded the SSD to the OWC NVMe Aura Pro X, which is unbelievably fast ... And, everything works beautifully.

EXCEPT when I put the laptop to sleep. At some point during the sleep, something "happens" and then when I go to open the lid to the MBP, it immediately does the startup sound, black screen for about 10 seconds ... Then a second startup sound, black screen for about 10 seconds, then the Apple logo and the bar. After that, everything works perfectly.

Someone had mentioned on another forum that this issue is potentially due to the NVMe drive not being 100% powered up in time for the SMC to find it, and so it then just does a hard reset until the storage device is available.

For me though, I don't get any error message. Nothing in any of the system logs, either. It's as if nothing "bad" even happened. So, it is very baffling. Would imagine Apple knows about this, hopefully they come up with a fix ASAP.

Hi,

Same issue here. Stop doing tests because nothing will solve that issue. What I recommend is waiting for the next upgrade 10.13.2 to see if they will solve that!

i’ve been getting sleep wake failures on my 2013 imac since the upgrade to high sierra. is anyone still getting the failures with the latest update 10.13.2?

Dec 8, 2017 10:09 AM in response to fmiguel

Ok, I've just updated to 10.13.2 myself. I will check for the next few days and get back with my findings. Hopefully not going to have to go back to Sierra again.

MacBook Pro (Retina, 15-inch, Mid 2015) same issue. 😠

You're NOT waking up from sleep? So if not waking up do you mean you come to find your laptop has already rebooted on its own?

nice try 😉

But it's my Macbook which does not wake up.....

If your Mac wakes up under High Sierra you seem to be a lucky guy 😉

Dec 11, 2017 11:41 AM in response to Hlohner

I hate to ask but could you unplug your laptop from power and run the same command? I am not sure the -b option is doing what I think it's supposed to do.
