Sleep issue with MacOS HighSierra 10.13

Update: It would seem that disabling power nap for both charger and battery power has "resolved" this for me, while i don't consider this be an actual resolution, it's an adequate fix for now as power nap was not something i really cared about. One slight annoyance is that all of the notifications checking is behind if the PC has been in standby for a while.

I ran into the same issue, but got some hints from some Mac friends. They suggested looking at the Activity Monitor and I noticed that Photos was running some background tasks with high CPU usage. After the initial upgrade to High Sierra, Photos will run a background task to index things like faces and places. This is likely a different index than Photos under Sierra. This background task took over 2 weeks to run and fully index. Once the index was fully built, then my Energy Savings setting kicked in and my Mac would go back to sleep after inactivity.

2)I’ve checked both settings already

Did you take a test on sleeping time?

In Security & Privacy - General setting, you can set time for "required password" after sleep.

Set 1 min. , for example, and make your Mac sleep then make it wake up before and after 1 min.

Also, make sure to uncheck "prevent sleeping automatically when the display is off", and turn off automatic login ,which might not be for sleeping though.

After these test, If you are not asked to login after sleep, call Apple.

For the first issue, it happens when battery is very low.

For the second one, Security & Privacy - General setting affects. Energy Saver setting may also affects.

Note that Energy Saver setting affects wake-up performance, if you feel wake-up time is long, try "restore default" option.

I am also experiencing an issue with sleep/standby since updating to high sierra, (late 2013 model MBP) sleep does not occur when plugged into battery or on the adapter. Reset NVRAM and SMC so far, and i had power nap ON for AC power and OFF for battery, so i will test having it off for both.

Hi,

You're not alone with this problem that apple can not fix.

My suggestion to avoid headaches go back to Sierra until apple introduces new macOS update

I have this problem on my iMac. It happens almost every time it goes to sleep.

I don't have power sleep on.

I have the most recent version of High Sierra. 10.13.2

I am updating today with the High Sierra 10.13.2 "supplemental update" - I am hoping that fixes it.

iMac late 2012

I have issues with my iMac since updating to High Sierra. Whenever it goes into hibernation it takes several minutes to load the login screen (instead of the usual 10-15sec), or it can freeze upon logging on and I have to restart it by pressing the on/off button. There are serious, sometimes fatal hibernation issues.

I have the first issue, and my battery is seldom below 90%.

I have the same problem with my desktop iMac. This is so aggravating.

This started for me immediately after doing the upgrade. I've modded all the relevant power and sleep settings to no avail. It's SUPER annoying because it dumps all my open tabs on chrome for example after going into essentially the powered off state, when it should really just be in sleep.

If you're having this problem, you should check if you're able to create new users as well. I found I was completely unable to add a user to my system after doing the upgrade.

The latest wave of MacOS upgrades feel more inline with the lower caliber of iOS upgrades I've seen over the years.

It is discouraging that this is happening with seemingly increasing frequency with these updates. You may want to reinstall the latest version if you can. It seemed to clear up my frustrating issues and it may work for you.
