I tried on my ML installer, i got up to PCI Configuration Start, then it hangs. Could be because i have a GTX 780 installed atm, might try with the ATi 4850 later.

Using Transmac i replaced mach_kernel on my actual OSX partition, that got up to NullCPUPowermanagement Kext loading then it hung.

 

I used Pandora and ML 8 and that other Kernel.  All is fine and then it hung and gave me waiting on root device... again.

I'm still on chameleon bootloader, this OS has had no modification from the working 3960x (10.8.4) build except adding the Mach_kernel file and using DSDT=No flag.

I haven't encountered root device error in my troubleshooting so not sure why that's happening.

I couldn't get chameleon to boot my old OS.  it just goes blank.  so i've been using the one packaged with pandora install.  even when i use teh same one (rev 2248) I get nothing.

I booted into Windows and used Transmac to replace the mach_kernel file that was on the OSX partition that i also could not get into (same issue black screen), then with -v -f DSDT=No it boots.

 

You need to somehow edit that mach_kernel file on the root of your OSx Parition without booting into it.

 

I think if you create an OSX installer with myHack and replace the mach_kernel file that should be able to boot too, providing the rest of the system is compatible.

Hi,

 

May I ask you a few questions about your System right now?

 

1. Do you get some kind of power management? Any turbo mode? Which multipliers?

2. As I understand NullCPUPowerManagement mandatory for now?

 

I intend to go with i7 4930K to replace my 3820, if I can get full Power Management with OS X 10.9.

 

Thanks! :-)

Rampagedev will know better, currently im using NullPowerManagement but with a corrected DSDT and sleepenabler.kext i can get sleep to work.

 

I dont believe full power management works in Mountain Lion but in 10.9 it should as Apple are using the socket 2011 CPUs.

 

My CPU is overclocked to 4.6Ghz but i think its performing at its stock 3.6Ghz as Geekbench score is 18000, whereas on my 3960x at 4.6Ghz in 10.8 i hit 22000.

 

FakeSMC doesnt support the Ivy-E CPUs yet so my iStat and HWmonitor are not working to check the speeds of the CPU and Multipliers/Voltages. Im assuming that with that Geekbench score its running at stock, no idea if its speedstepping or Turbo'ing at the moment.

Updating to 10.8.5 has killed the system, without the Mach_kernel replaced you get black screen, with replaced I get kernel panic from AppleACPIPlatform (unable to find driver for this platform).

Maybe 10.8.4 AppleACPIPlatform kext will fix, but have no access to one.

Thanks for the info ;-)
 
I've attached 10.8.4 AppleACPIPlatform.kext for you

Many thanks, im wondering if it should bother trying though, as i have no way in repairing the permissions after swapping the Kext through Windows, itll probably end up not liking the replacement kext at all, any ideas before i try it?

 

Edit

 

Did it anyway and its back!  :lol:

What's back? Kernel Panics?
Or your usable OS? :)

I finally got myhack to boot and try to load the OS. but it still hangs.

 

can you tell me which kernel and special kexts you used on your original install?  and, if possible, could you upload them for me?

Got a fresh install of Mountain Lion up and running.  This was the process:

 

1.  MyHack installer with 10.8.5 install

 

When done, add these to /Extra/Extensions

 

ML 10.8.4 AppleACPIPlatform.kext (from subdleku's link above)

VoodooTSCSync.kext from rampagedev.wordpress.com

 

(In addition to the defaults)

 

Swap the default Kernel on the installer with:

 

http://www.osx86.net...pic-fix-kernel/

 

If you can't just cut and paste, go to terminal and try something like

 

cd /Users/user/Downloads/Folder WIth Kernel/

sudo cp mach_kernel /Volumes/my hack disk name/

 

Run MyFix on myhack installer

 

Setup bios to boot to USB, use these falgs

 

-v -f DSDT=No GraphcisEnabler=No npci=0x2000 PCIRootUID=0

 

Run install

 

Now, you'll need to boot back into the installer and go to terminal

Copy the mach kernel from the root of your myhack disk to the root of your new operating system

 

E.g.,

 

cd /Volumes/myHack*

sudo cp mach_kernel /Volumes/OS\ X/

 

You also need to copy your kexts

 

I did this by going to the extensiosn folder in the myhack installer (e.g., cd /Volumes/MyHack...)

then use thsi command for each important one

 

cp -R file.kext /System/Library/Extensions

 

If you don't copy the ACPIPlatform.kext again, you'll get KPs on boot.  Copy other important kexts (i.e., ethernet, voodootscsync)

 

exit terminal

go to disk utility

 

repair permissions on your main install

 

Boot into OS X, make sure to type bootflags again

Install Chameleon, update your bootflags, etc.

 

 

And you're rocking.

 

 

I haven't tried to get sound working.  But otherwise things are fast.  Check out these Geekbench scores when overlcocked to 4.0ghz

 

Phew!!!

Calling it a night.... I'll try Mavericks tomorrow using similar methods.  Cross my fingers....

Used tha Alc 898 patch for my Asus P9X79 Pro board with HDEF edits in DSDT for Audio support. Sleep is also fixed.

Is the custom kernel required for these? Any news on Mavericks?

So far that kernel is the only one booting Ivy Bridge-E, as for 10.9 im not sure.

Ive managed to get a Geekbench score of 20k with 3.6Ghz, it isnt overclocking even with C States and Speedstep disabled.

 

MSRDumper and HWMonitor both report x36 Multi.

 

One more issue, the vanilla AppleIntelCPUPowerManagement.kext will not allow the Kernel Cache to build. Using the 10.8.5 patch in Mult1beast does allow the Kernel cache to Build, but results in a Kernel Panic (Unrecognized CPU) on reboot.

 

Without AppleIntelCPUPowermanagement.kext installed (and without NullCPUPowerManagement) the C States seem to work and sleep works too. But still cant get it to Turbo to my overclock. Not sure if AppleIntelCPUPowermanagement Kext is related to the overclock.

 

Im going to try Mavericks soon.

 

Tried Mavericks, it wont boot the installer, same black screen issue (Kernel issue again), so i tried the patched 10.8.4 kernel that worked previously, but that didnt work for obvious reasons (gave it a shot anyway).

Yeah... I've been happily using 10.8.5 on my 4930k.  It's stable and fast.  No complaints.  Not gonna tinker at all until Mavericks with LGA 2011 support comes out.  So I'll give a shot with each new kernel from new developer previews.  Whenever the Mac Pro gets close to release, it will probably work.  Waiting....
