Hey guys, running big sur 11.2.3 opencore 0.6.8 with all latest plugins.


the machine wakes up immediately after sleep, could somebody help me out here. 



  • 4 weeks later...

Before this update Sleep/Wake function was flawless (USB ports properly Mapped), with the latest update, Sleep/Wake function is somewhat flaky - sometimes it will work another time it will not but then again I am running Beta 11.4 Beta (20F5046g) although I have 11.3 on a test disk that I haven't tested the Sleep/Wake feature as yet.

I have also some sleep that are not working . It was working at 100% under Mojave, and Big Sur until the 11.3 update, and now Sleep is not 100% working after the delay I have decided. 

But we have logs : 


In a MacOS teminal : type the follwing; You will have the start of each event and a cause

pmset -g log|grep -e " Sleep  " -e " Wake  "

for me : 

2021-05-04 12:05:13 +0200 Sleep                   Entering Sleep state due to 'Maintenance Sleep': Using AC (Charge:0%) 533 secs
2021-05-04 12:14:06 +0200 Wake                    Wake from Normal Sleep [CDNVA] : due to GLAN/UserActivity Assertion Using AC (Charge:0%)
2021-05-04 18:45:04 +0200 Sleep                   Entering Sleep state due to 'Software Sleep pid=158': Using AC (Charge:0%) 511 secs
2021-05-04 18:53:35 +0200 Wake                    Wake from Normal Sleep [CDNVA] : due to GLAN/HID Activity Using AC (Charge:0%)


First sleep at 12:05 was after a 30 minutes delay: OK 
It should have go to sleep 30 minutes around 15:00:00 (I was no longrer at home) : It didn't go to sleep.

Does your units have powernap?


set sleep to 1

standby to 0

hibernatemode 0

no wake for network access

set powernap to 20 and it powernaps. Provided you have booting up and set to XCMP X86 Plugin power management.


Have to periodically check your BIOS CMOS after tinkering around with kexts patches. CMOS resets happen when we least expect them to.


USB  Wake on to NO (however it is written in your system)

Wake on LAN/WLAN to NO

Powernap to YES (which turns on virtual hyperthreading)
