Sleep Wake Failure with High Sierra 10.13.2

Since installing 10.13.2 I have a sleep wake failure on iMac. Was working perfectly before installed latest update on Dec 8.

This is not an uncommon problem but the "fixes/solutions" one reads on the internet are all over the place.

Is there a fix or is this simply something only Apple can solve for all those now plagued by the problem? It is irritating in the extreme.

iMac, macOS High Sierra (10.13.2)

It isn't a problem with the update. I do not have such a problem. Didn't have a problem with 10.13 or 10.13.1 either. My suggestion is a problem in the underlying system you upgraded. So, the first thing I will recommend you try is this:


  1. Resetting your Mac's PRAM and NVRAM.
  2. Reset the System Management Controller (SMC) on your Mac - Apple Support.
  3. Boot into Safe Mode - this takes longer than normal.


The second thing you want to do is:


Repair the Drive for El Capitan or Later


  1. Restart the computer and after the chime hold down the Command and R keys until the Utility Menu appears.
  2. Select Disk Utility and press the Continue button.
  3. Then select the indented (usually, Macintosh HD) volume entry from the side list.
  4. Click on the First Aid tab in the toolbar and wait for the Done button to activate. Click on it, then quit Disk Utility.
  5. Select Restart from the Apple menu.


The third thing to do is: Download and install the macOS High Sierra 10.13.2 Combo Update.


That's it for now. After the Combo Updater is completed your computer should restart. However, if it does not then restart the computer normally.

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


There are 637 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!

Everyone who is having problems because of the premature release of High Sierra needs to call tech support and complain. I am sure there are many more people out there that are having problems but haven't reported it yet so Apple is not making this a high priority fix. My sister has been having her MacBook crash since HS but she just thought it was a random problem and hasn't reported it. I just sent Apple my third error log this week. I am now working with my 6th different advisor and he claims they are "focused on the problem" but Apple has yet to publicly acknowledge the problem and the engineers won't even give the advisors any kind of updates. So it appears they will continue to take there own sweet time until there is enough adverse public opinion to get the on the stick. If anyone knows how to get this problem out in the news that might help. COME ON APPLE!!!!

I wish Apple would simply acknowledge that this is a known problem and that they're working on a fix. Calling support is an exercise is frustration. Restart, reset SMC, reset PRAM, reinstall, etc. Basic decision tree crap that does nothing. The latest suggestion was to create a "test" user account to see if the problem reoccurs. Good grief! Once I realized that I would need to reenter all of my passwords, re-set up email accounts, etc., I said screw it and decided I could live with the problem until they get it fixed in a future OS update.

I have the same issue on my late 2013 iMac. Apple/AppleCare are in denial that it has anything to do with High Sierra. They act like no on else is having this issue. Their 'default' solution is to wipe the drive and do a clean install of High Sierra. Hopefully they will realize this is a fault and update the OS soon....

I have the same problem. Every morning I log in and am greeted by a message about a sleep-wake issue and asking me to give permission to send the error report to Apple (which I do - but do they do anything with it?).


Also, recently after the latest OS update, my screen remained gray all night with a completed status bar showing. I did a hard restart and the iMac booted ok but that sleep-wake message persists.

The second time I called support back in November they tried to get me to wipe my computer. Luckily I had already found a report of someone trying that and it failing to help so I didn't go thru that agony. Apple has asked me 3 times for error files and they keep telling me they are working on the problem but it must not be a high priority as long as it is taking them to do anything. I have also been sending the generic anonymous reports every time I get the restart SW FailUre. The link they sent me to send them the error logs stays open for 30 days so I have also been sending them the report every day my computer restarts so they have the specific info that should tell them what the problem is. They probably aren't even looking at them however. Can't believe how screwed up this is. If they every do get Lowdown Sierra fixed I am never going to update my OS again.

Just sent my latest report to apple after yet another unexpected sleep wake failure restart. I lost count. This message is only to keep the community updated about the lack of progress on the situation. Yesterday I responded to someone's comment about apple's inconsiderate approach to this problem. Apple removed my message!

I suspect that the problem lies in a rewrite of all or a portion of the screen saver module in High Sierra. I recall that after installing 10.13.x last year, I could not run the BOINC screen saver for a few weeks until they rewrote their code to work with new screen saver APIs in High Sierra.


What is unusual for my iMac is that occasionally, when trying to wake it from sleep using the keyboard, I get no response. Pressing the power button briefly causes it to wake and restore the contents of RAM from the hard drive. I have only ever witnessed this behavior before on my MacBook when the battery is near death and as its final gasp, it saves the contents of RAM to the hard drive.

I am using a brand new iMac Pro and am having a similar problem. When I wake from sleep a gray screen opens ope and notifications show on right side of screen. External hard drives thrash away, then after about 15 minutes the screen itself wakes up and I can work. I think the problem is somehow related to external drives and porting them through the thunderbolt 3 port.

I've been following this thread since December 2017 when I upgraded my late-2012 iMac 21.5" to High Sierra. I'm currently running 10.13.3. Like many others, I've tried all of the suggestions in this thread and nothing works. I keep getting the sleep wake failure every single time my computer goes to sleep. My workaround has been to disable sleep completely, and this obviously works, but I don't like leaving the computer on all the time.


Just chiming in to plead Apple to fix this problem. If there are others out there lurking on this thread, please chime in. This needs a fix.
