Question: Sleep Wake Failure macOS High Sierra 10.13.2

Since I updated to macOS High Sierra on December 18, I have been getting a Sleep Wake Failure on my 27" iMac. Can I fix this or do I need to take it in to Apple?

iMac, macOS High Sierra (10.13.2)

I went the radical way and reinstalled the OS. All data is simply copied from an external hard drive, without copying the folder Library. The problem has not gone away. Diagnosis shows that everything is ok. Resetting SMC and NVRAM does not help either. If not mistaken, the problem appeared with the release of 10.13.0.

Possible Fixes for El Capitan or Later

You should try each, one at a time, then test to see if the problem is fixed before going on to the next.


Be sure to backup your files before proceeding if possible.


  1. Shutdown the computer, wait 30 seconds, restart the computer.
  2. Resetting your Mac’s PRAM and NVRAM
  3. Reset the System Management Controller (SMC)
  4. Start the computer in Safe Mode, then restart normally. This is slower than a standard startup.
  5. Repair the disk by booting from the Recovery HD. Immediately after the chime hold down the Command and R keys until the Utility Menu appears. Choose Disk Utility and click on the Continue button. Select the indented (usually, Macintosh HD) volume entry from the side list. Click on the First Aid button in the toolbar. Wait for the Done button to appear. Quit Disk Utility and return to the Utility Menu. Restart the computer from the Apple Menu.
  6. Create a New User Account Open Users & Groups preferences. Click on the lock icon and enter your Admin password when prompted. On the left under Current User click on the Add [+] button under Login Options. Setup a new Admin user account. Upon completion log out of your current account then log into the new account. If your problems cease, then consider switching to the new account and transferring your files to it - Transferring files from one User Account to another.
  7. Download and install theOS X El Capitan 10.11.6 ComboUpdate or 10.12.6 Combo Update or macOS High Sierra 10.13.2 Combo Update as needed.
  8. Reinstall OS X by booting from the Recovery HD using the Command and R keys. When the Utility Menu appears select Reinstall OS X then click on the Continue button.
  9. Erase and Install OS X Restart the computer. Immediately after the chime hold down the CommandandRkeys until the Apple logo appears. When the Utility Menu appears:
  1. Select Disk Utility from the Utility Menu and click on Continue button.
  2. When Disk Utility loads select the drive (out-dented entry) from the Device list.
  3. Click on the Erase icon in Disk Utility's toolbar. A panel will drop down.
  4. Set the Format type to Mac OS Extended (Journaled.)
  5. Click on the Apply button, then wait for the Done button to activate and click on it.
  6. Quit Disk Utility and return to the Utility Menu.
  7. Select Reinstall OS X and click on the Continue button.

Kappy, I appreciate your advice but I did all of that and it still auto-restarts. Reset SMC, NVRAM, SRAM, restarted in Recovery, used Disc Utility First Aid in Recovery. Yesterday took hours (used 2nd security option of 2 rewrites) to erase HD and reinstall OSX all from recovery. Then of course got update notification so updates with recent Supplemental. Nothing changed. I think this has got to be a problem with High Sierra. I've had this issue since 1st High Sierra installation months ago.


**Previous to erase/reinstall, when I started in Safe Mode got a lot of flickering on monitor and slower response on everything. Some programs are disabled by design. BUT, it DID NOT RESTART during a roughly 24 hour test period. Normally restarts randomly within minutes to hours. I don't know what this means or how this can help. Any thoughts?

I was just told yesterday that this is a "known reported issue" I said well is it a bug? Apple guy said we do not like to call anything a bug because there are bad vibes with it... we call it a known reported issue. That is just fine Apple, whatever you want to call it... just fix the "known reported issue" so there will be NO "known reported issues".....

It is so frustrating to feel that Apple is not telling us the truth... my first senior advisor keeps telling me to take it to the apple store to wipe it out... really for a software bug = known issue!!!!!

By the way can someone change the header of this thread to even says 10.13.3 - the latest and greatest has the "known reported issue = bug"

Updating to 10.13.3 didn't change my issue either although it's not happening quite as often. That could also be because I am manually putting the computer in sleep mode from the Apple menu when I step away.

I am the original poster, but it won't let me amend the post to 10.13.3.

I don't know what happened but everything works fine. I erased and reinstalled OSX (3 times) but still did not fix sleep wake failure. 2 days later it appears everything works fine now. 2-3 Days and no sleep wake failure. YAY!!! Thank you Apple for finally fixing this.
