[QUOTE="chscag, post: 1776610, member: 46727"] A "Sleep Wake Failure" error does not generate a kernel panic report but will be noted in your logs. I have had that very same thing happen after a security update to High Sierra and it also prevented my iMac from going to sleep. However, the error only occurred one time not every day. The only cure I found was to reset the SMC. Give that a try and make sure you have the latest High Sierra update installed. (10.13.1) [/QUOTE]
