shl628 Posted July 26, 2021 Share Posted July 26, 2021 (edited) I have same problem. It seems possible to enter sleep mode. However, when the computer wakes up from sleep, the screen goes blank and after a few seconds the computer automatically reboots. But, the interesting thing is that when the SMBus controller is loaded, there is no reboot problem and the screen comes on well. When SSDT-SBUS-MCHC.aml is loaded, the screen comes on well when the computer wakes up after entering sleep, but the cooler fan does not turn off even after entering sleep.

I have read through the Sleep Fix in the OpenCore Post Install Guide and tried all of them, but the waking issue is not resolved. https://dortania.github.io/OpenCore-Post-Install/universal/sleep.html And, Hibernation via HibernationFixup.kext (Hibernatemode 25 & 3) didn't work either. So, I'm currently using the sleep feature with disabled. sudo pmset -a disablesleep 1 Edited July 26, 2021 by shl628 Link to comment Share on other sites More sharing options...
