Sleep-Wake Failure

My iMac running OS High Sierra has for last several days experienced a sleep-wake failure. The diagnostic report has a repeating section as follows:

Thread 0x3ec8cd Thread name "thread call kernel-high #3" 8 samples (1-8) priority 92 (base 92)

*8 call_continuation + 23 (kernel + 116055) [0xffffff800021c557] 1-8

*8 ??? (kernel + 673285) [0xffffff80002a4605] 1-8

*8 machine_switch_context + 205 (kernel + 1580685) [0xffffff8000381e8d] 1-8

Can anyone help me figure out what's causing this and tell me what I can do to correct it?

Thanks

iMac 27″ 5K, macOS 10.13

Hello WuLi,

That report doesn't help much, but normally those types of failures are due to an nupdate or corruption breaking something.

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

EtreCheck is a FREE simple little diagnostic tool to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac. It will not display any personal info.

Pastebin is a good place to paste the whole report if you capture the URL while there…

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

The important part of the above is...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
