ASUS Sabertooth Z-77 Yosemite install only boots with -x

[Vosster]

Hi so now in your thread, because mine ins't working at the moment.

If your system fails to boot from hdd, boot from usb and enter

/System/Library/Kernels/kernel

as boot flag.

This should bring you into the system. In Multibeast DISABLE AppleIntelPowermanagement.kext! In fact be sure it's no longer installed and in your /System/Library/Extensions folder. Instead install the NullPCPowermanagement.kext!

Yosemite is the first OSX version that requires this procedure instead of the exact opposite in previous releases.


EDIT: You can have a look at the multibeast settings for Yosemite in my thread now.

So I followed your method Vosster, and I get stuck on this hang screen with just -v

A little different from you is that I have to install with -x and GraphicsEnabler=Yes. GTX570 doesn't register automagically.
Also did you delete the AppleIntelPowerManagementClient.kext also? It's different from AppleCPUPowermanagement.kext. And also why do you have 3rd Party eSATA vs 3rd Party SATA?

Note after this hang I added the AppleACPI Rollback and now I can reboot without having to shut off my rig first, but still hangs there.
