Fix Hackintosh Sleeping Issue


To get sleep working in Clover is fairly straightforward. It should function normally once speedstep is enabled. However, not all devices will wake the machine (I.E. mouse and keyboard). Single pressing your power button should wake the machine if these do not.

What is Speedstep?

Intel Speedstep is a power management function which allows your CPU to slow down when it is not under heavy use. This saves power and lengthens the life of your CPU.
To get this working in Clover we will need few things set up.
  • A DSDT must be present in /EFI/CLOVER/ACPI/patched
  • P and C state generation needs to be enabled. (this generates the SSDT tables needed for power management)
  • The HPET patch needs to be applied in the Clover Configurator

Extract Your DSDT

Download the DSDT extraction script from RampageDev
Double click the script to run it.
You should now see a DSDT.aml file on your desktop.
Copy it to /EFI/CLOVER/ACPI/patched

Enabling Speedstep in the Clover Configurator

Launch the Clover Configurator.
Load your config file File->Open->/EFI/EFI/CLOVER/config.plist
fix speedstep
Make Sure P and C state generation is enabled.
Enter the name of your DSDT under the DSDT name (note: the name should be DSDT.aml and it is case sensitive)
Check the FixHPET option under the fixes. UPDATE: 10.9 does not required HPET to be fixed.
Save the file and exit.
Reboot to apply changes.

Common Fixes

If sleep does not function, try the following.
  1. Make sure you do not have NullCPUPowerManagment.kext installed in either /System/Library/Extensions or /EFI/CLOVER/kexts/10.9
  2. Enable the AppleRTC patch in the Clover Configurator.
  3. If you are using UEFI try removing the CsmVideoDxe driver from /EFI/CLOVER/drivers64UEFI (You may not have this installed, so if it isn’t there don’t worry.)
