Power Management for Sandy Bridge and Ivy Bridge Laptops

Hi. i have problem with PowerManagement. In the beginning everything worked fine. I had 6 states in log of DPCI Manager. But now DPCI Manager's log says this:

03.12.13, 23:36:34, com.apple.kextd[12]: /: kextcache has had enough tries; not launching any more

You have installed some incompatible kexts. Be careful with installing random stuff/rollbacks, stuff you download on the internet. Strive to keep your system kexts as close to native as possible.

RehabMan, I found the reason of that. IOUSB. kext crashed my system. But now I use GenericUSBXCI.kext from MultiBeast and everything is fine. Also Thank you for you patches for DSDT. They are awesome. But sleep doesn't work on my laptop when i close it. May be you can help with this, guru?:)

See post #1. If sleep is still not working, describe fully the actual issue.

"First run of Multibeast (make sure you are using the latest version) select the following options:

- UserDSDT or DSDT-Free Installation
- Drivers & Bootloaders -> Drivers -> System -> Patched AppleIntelCPUPowerManagement
(be sure to select the version appropriate for the version of OS X you have installed)
- Customization -> System Definitions -> MacBookPro8,1..."

but I just can install the Multibeast if I finish the install and enter in the Mountain Lion, how can I fix it early this screen ?

You need to boot "-f" using your Unibeast USB, then run Multibeast and setup power management.

The SSDT is not correct, and doesn't even look like it is generated from MaciASL. Use the ProBoook Installer to generate your SSDT instead.
