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.
