We'll never stop working in the Developers Corner!
CodeRush is working hard on his utility to patch UEFI BIOS PowerManagement modules to be compatible with MacOS X SpeedStep implementation.
The utility works very well with a lot of motherboards, but he is still working to improve it.
Testers are required to help him!
Been using the Uh1 UEFI BIOS on the Gigabyte GA-z68-ud3h-b3 with very stable up time.
However, I've never been able to get either "shut down" or "sleep" to function.
I am using an extracted / vanilla DSDT only modified to get the HDMI audio working on my gtx670 - that is working fine.
I believe there must be something wrong in the DSDT because when I try to shut down or sleep the monitor shuts off and the computer appears to log off, but then it hangs and never actually completes the shut down/sleep function.
Reset works fine, so at the moment I have to shut down the computer by choosing reset and then holding down the power button when I see the BIOS splash screen.
Functional, but not convenient.
Can anyone help me to get either sleep or shut down working correctly?
