In making sleep simple or using native power management for some cpus, when updating to a new OS version you may discover that Apple has "consolidated" sleep to a single slider bar in Power Management; the Computer Sleep slider bar has disappeared. However, in doing so, the computer doesn't really sleep, since the new consolidated method is supposed to allow certain tasks to continue when the display turns off.
This just happened when going to 10.12.5. Credit for the following goes to other sleuths; I'm just posting it again for convenience. To restore both sliders, modify "/S/L/E/IOPlatformPluginFamily.kext/Contents/Plugins/X86PlatformPlugin.kext/Contents/Resources/Your-Mac-Model.plist"

find:
<key>UnifiedSleepSliderPref</key>
<true/>

replace with:
<key>UnifiedSleepSliderPref</key>
<false/>

It should be Mac-AA95B1DDAB278B95

for others looking for the proper file for their Mac model you can find this identifier in Clover Configurator
go to the SMBIOS tab and under the Board section, this identifier is the "Board-ID" value
copy that and paste into the Finder search bar and select Search: Resources, the folder it is in, because it will not come up if you still have it selected as Search: This Mac (you should already be at the "resources" folder. the path is listed in the very first post!)


This edit did work for me as in it did alter the Energy Savings app to show the Computer Sleep slider and removed the Power Nap check box option. However, it did not resolve my sleep and/or wake issue yet. Though I really will never use sleep in macOS, I am still having some OCD from having this one minor issue occur which prevents me from having a hackintosh that works just like a real Mac

Followed the guide and got the computer sleep slider back, but now enable power nap and start up automatically after power failure options are gone... OS version: 10.15.2 - Mac Model: iMac 19,1. Any suggestions on getting those 2 options back?

Hi jelle84,

Did you manage to restore those two options to your iMac 19.1 config?

I'm having the same problem after putting all of my board and system ids in order. Back on 18.3 Power Nap used to work for me, but the ids were messed up due to my usage of one of OsxAptioFix2Drv-free2000. So while migrating to OpenRuntime I decided so adjust the SMBIOS to my hardware (i9900, MSI Z390 ACE) and here I am... :(
