It kept happening and happening over and over again, regardless of what I tried. PRAM reset didn't help, SMC reset didn't help, installing the 10.14.2 Combo update didn't help - nothing did. It crashed again yesterday after a mere three hours of sleep while I went for a doctor's appointment during the day.

I've reverted back to High Sierra now. Who would've ever thought that Apple would manage to create an even bigger piece of sh.. than 10.13? Kudos, Apple. Kudos.

I'm still running High Sierra (installing Mojave causes disk management error) and the problem went away after installing Security Update 2018-003. I also removed a 16GB memory module which was running fine on 8GB for many years after I'd read @wubbzy comment but that didn't solve the problem by itself. So maybe the update alone or the combination of the update and RAM changes did it. On my Macbook PRO and MacMini it never happened so it looks like problem about a combi of hardware and software.

I found out that even using the Amphetamine app to keep the iMac awake, it still crashes. I'm not sure on the timings, but maybe after 4 or 6 hours.

My iMac has a fusion drive, just wondering if there are any non-fusion drive iMac users with this problem?
I have a Mid 2010 2.93GHz i7 iMac. Just had this exact problem about a week or two after upgrading from Mavericks to Sierra. It had been asleep for about 45 minutes, then rebooted while asleep. Looking at Console I can see multiple crashes every day for the process mds_stores (path: /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/Metadata.framework/Versions/A/Support/mds_stores) A crash report was created which I duly sent off, but the crash report states it was a 'Sleep Wake Failure'.

Can anyone running 10.14.4 who's been plagued by constant sleep wake crashes with earlier versions of Mojave comment on the current situation? Has Apple finally fixed it or do (i)Macs continue to crash while asleep?

I am still having this issue, I'm on 10.14.5 granted I'm working of an external ssd so that could be the problem, but I've been having this issue since I purchased my 2017 iMac so I've gone through every Mojave update. I also have a fusion drive, anyway it happens less and less each update but honestly its still happening and that is a very frustrating experience. I usually know its about to happen when my iMac stops waking instantly, it will hang for a moment , then wake up then it gets buggy until it starts regularly crashing.

Thank you very much for that update, @Hambone2.
I've given up on 10.14 and am going to wait for 10.15 hoping they fixed this issue in Catalina. We'll see...

Reinstalling macOS doesn't fix the issue. Only my iMac is affected, no issues with my MacBook Pro.
It didn't for me, either. Very frustrating.

Moving the .plist files is on the Support rep's list of NEXT things to do tomorrow, if necessary. I'll wait til then.

Any chance the rest of you, with this issue, were using Sophos Home anti-virus or Malwarebytes (free edition), too?
I am using malwarebytes.

I no longer have Malwarebytes, but I did not find that to be related to the problem.

Unfortunately, solutions - if any - are varied. What worked for me, didn’t help anyone else out. Others found solutions that worked for their particular configuration. Apparently, the causes are as varied as the solutions.

It’s an annoying bug.

Do you folks have a third-party drive? I have been having issue and I was under the impression it was because I replace my factory SSD by a OWC Aura Pro X...?
Do you still have this issue with Mojave or even Catalina?
Any help would be much appreciated :)
Thanks!

No, I have the stock "fusion drive" in my iMac.
I haven't seen this issue in a long time; so, certainly not in Catalina.

Wish I could help, but causes & solutions are varied. Have you talked to Apple phone support -- they help with software-related issues, like this one.

I have the stock 1TB Fusion Drive and have not seen this issue in Calatina yet. I've updated my iMac 19 days ago and have put it to sleep every night since, and it has not crashed once:

Bash:
iMac:~ martin$ uptime
10:19  up 19 days, 14:28, 2 users, load averages: 1.10 1.31 1.37
I am thus confident to report that whatever the issue with Mojave was Apple seems to have fixed it with Catalina.

@LeChat I've heard about these issues with third party drives regularly, and long before the release of Sierra, High Sierra or Mojave. I believe in your case it is most likely related to the third party drive and not the operating system. Seems to be hit and miss.

Just to be clear, the problem stopped for me before Catalina. So, for me, Catalina didn't fix anything. :)

I have not gone through every post, but I’ve had this problem for a very long time.

Typically crashing and hanging after sleeping in this case is often related to non OEM HDD/SDD installed in the iMac. I have both.

In recent releases I noticed that my machine would sleep, but things like appnap would “wake“ the computer and cause a crash and restart. After many “report to Apple” I kinda figured its pointless, so I have just turned off sleep, appnap and prevent drives from sleeping and I don’t have any issues.

It believe its goes hand in hand with the system fan not auto regulating (need for 3rd party software to do this) after a non OEM drive installation. Must have something to do with the custom firmware on the OEM drives.

Thats my 10c and my experience after digging deep into the logs and crash logs. Hope it helps.
