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)
I had the same problem on a macbook air (13-inch, Mid 2012, macBookAir5,2) since OSX 10.13.2.
I tried everything proposed on this and on other forums.
Recently, I did 2 things:
1) I downloaded 10.13.4 FULL installer (no combo, the full installer) and reinstalled High Sierra, over the previous installation.
2) I replaced the SSD disk few years ago, I have a OWC Aura Pro 2012 480GB SSD disk. I became aware of a conflict between high sierra and old OWC aura disks. I updated the firmware version to 603ABBF0 (got it from here: OWC Mercury SSD Firmware Updater via USB Drive or CD/DVD Disc). The problem also affects other OWC Aura models (http://macosuninstaller.com/one-click-removal-tutorial/unfortunately-time-owcs-a ura-ssds-not-support-macos-high-sierra/).
Since 1 and 2, the black screen/freeze after sleep, as well as a blinking folder with question mark at boot issue, stopped. I keep my finger crossed. Hope this helps.
Just to keep the ball rolling: same problem on my 27" late 2012 iMac - OS 10.13.6. This is a work computer, so I'm not running anything out of the ordinary: most are core apps, plus Logic Pro and the messaging app "Telegram". Other than that, nothing weird.
It seems to me - and it's an observation, so I could be wrong - that the longer the Mac has been in sleep mode, the more unlikely it is to wake.
In all other respects the machine works fine... but it is irritating and Apple should be looking to fix this.
Sadly, while lying in bed reading last night, I heard the dreaded double chime of restart from my iMac. SWF once again. This was with 10.13.6 installed with Power Nap enabled. 2,100,000 seconds (~24 days) since last restart. That's about when I installed 10.13.6. So disappointing and frustrating. Perhaps, when Mojave is released in a couple months, we'll finally be able to relegate this sorry saga to the dustbin of history.
Really sorry to learn about it, jtonn. It would have been utterly ridiculous, if it was not so painfully disruptive for such a long time now. How did they manage to only part-solve the problem! Compared to the pre-10.13.5 daily reboots, it is, admittedly, some progress, but why the SWF hasn't been eliminated completely is totally baffling. As you say, let's cling to hope :-/
I had this problem on my 2014 MB pro 15 inch (max specs). I had the problem persist and it would restart so many times the battery would drain between 60-80% in 1 hour. I would travel to work or a friends house (with max charge) and get to my destination with basically little to no battery. I did a full restore 3 times - at the apple store. Apple also removed and replaced my entire computer (except for the display) many times and the problem persisted. I spilled a tiny bit of water and the intake sucked it in, my 2014 MB Pro went kaputs.
Bought a 2015 brand new 15 inch MB Pro in June (when they still had the old ones - I got it for 1399 no tax 😀 big come-up). The sleep wake failure has happened 2 times since. I had set up the Mac completely new. Maybe after a whole year and a whole OSX later, they might have the problem resolved or even better, give us new software quirks, bugs, and garbage.
5 FRESH setups later (NOT EVEN TIME MACHINE BACKUPS), we still have the same problem but apple will still blame the user.
I feel as though something in the cloud is causing these errors. My iPhone X has a ton of issues and on amount of "set up as new" helps. I have set up my iPhone X as new twice since November and the same problems persist (even with a new device). Apple claims its impossible for there to be errors in iCloud, even for a power user (load of BS in my opinion). Apple ignores the issue because they are too big to fail. Just like all the iTunes issues they haven't fixed in 7 years. Without Steve, I don't know if they are launching items with proper testing or not. Seems like there is no more quality control.
I wouldn't hold your breath.
Same problem with my 2012 iMac. 10.13.2 breaks the Sleep. Fix coming????
Same problem with my 2012 mac mini running 10.13.2. The daily timer to supend it a midnight is not working any more. In the morning the timer warning "goind to sleep soon" is is still on the screen.
It worked on my iMAC. Thanks.
Nevermind. I put it to sleep after I was done posting that, and then five minutes later it rebooted itself. I give up. It's sad to think that my Windows 10 Surface Pro 4 is my stable computer.
No. Didn't even think to do that. It's on a separate disk (of course), but that could affect it? I know people have been reporting "runaway time machine" issues on this build, too. So weird.
Dear Kappy,
The 3 steps including the Combo Update didn't solve my Sleep Wake Faillure.
Apple please help.
Kappy, I tried first and third thing, after it, sleep worked on my iMAC, but after I use Apple TV, auto sleep do not work at all.
mrfloris, Can you say how one to know when the issue will be resolved and it will be safe to upgrade to High Sierra?
same problem mini mac 2012
I am also having same issue after the update.
