I got my new 4930k and got the system up and running in Windows.  No issues.

 

Haven't been able to get into my 10.8.5 install.  I also tried booting into Mavericks.

 

My issue is that I get through a verbose boot fine, but then I get a blackscreen.

 

I've tried a number of bootflags, mostly different combinations of:

 

-v npci=0x3000 GraphicsEnabler=no cpus=1 PCIRootUID=0

 

tried 0x2000 as well... all the same result.  I'm going to try a fresh install of 10.8.5 and see how it goes.

 

Anyone have luck with Ivy Bridge-E yet?

I actually haven't heard of anyone doing an Ivy Bridge-e hack yet... you'll certainly be one of the first few to attempt this!

 

Unfortunately I can't offer any help, other than to say that as the new Mac Pro's will be Ivy Bridge-e based, you shouldn't have too much to worry about CPU wise.

 

That said, are you sure the black screen is CPU related... could it be to do with your graphics? What GPU?

 

Anyway, please let us know how you get on... I'm interested to know what sort of power management we'll be able to get out of the box with IB-e and 10.9. The only drawback of the previous generation Sandy Bridge-e based hacks was/is the lack of it.

I am having the same problem with a Gigabyte GA-X79S-UP5 and an i7 3930k. Will work on it this weekend and let you know. I get black screen on ML 10.8.4 and CPU halted on Mavericks.

I am not sure the 10.8.5 kernel supports Ivy-E but I may be wrong.

Yep, I'm on the bleeding edge here.

 

I thought about that -- that it may be the GPU.  I have a pretty vanilla card - EVGA GTX650.  I used to just have to do GraphicsEnabler=no to get into the installer, and then I had no issues.

 

Now, I get through everything and only then do I get a black screen, and my monitor light turns off.  I get the same issue on OS X 10.8.5 (installed) and installer.  I also get the same problem with Mavericks install.  So maybe it is GPU

 

I've tried a number of boot flags, including all the usual variants of:

 

-v -x PCIRootUID=0 (or 1) npci=0x3000 (or 0x2000) GraphicsEnabler=no cpus=1

 

I've also added dsdt=No

 

so no luck. I'm downloading DP4 from the App Store now and I'll make an installer for that and see if I have any luck there.

 

Till then, I'm stuck in Windows 8  :wacko:  <_<

I just tried again, this time with the 10.9 DP 4 installer.  No luck.  I then noved my graphics card to another PCI slot hoping that would make a difference. Nope.

 

Gotta get focused on getting work done for now so can't tinker too much.  Always interested to hear people's ideas.

It doesn't actually hang. I think I've determined the bootloader doesn't support the CPU. It just doesn't load the os. I've been using chameleon bundled with myhack. So might need to try a different loader. See http://m.youtube.com...h?v=bEd8ln49EME

Same issue, working hack (10.8.4) from 3960X upgraded to 4960X, now after Verbose info completes, i just get a blackscreen, the OS doesnt load at all. I also think its a bootloader issue.

 

Im using Chameleon bootloader and MyHack installer with 10.8 Mountain Lion. The installer also suffers the same problem.

Some help getting clover to work? It sees my osx drive but it won't boot verbose with -v flag in bootargs and it just sits at grey apple screen with no hard disk activity.

I installed clover to a USB stick.

I am going to try with the latest Chameleon release, not the default one on MyHack.  I'll also try with Clover.  Report back later.

no luck with Chameleon.  Clover starts to load the OS (white screen etc.)   I get exact same problem as you so far (wont boot verbose even if I tell it to).  STill trying.

I was able to play with /EFI/CLOVER/config.plist to get a verbose screen, and play with boot flags.  If I do verbose & safe mode, I get the following:

Loading Drivers......

 

........ then some plus signs and it's dead.

 

I'm trying one last time with PandorasBox, but after that I think it's time to give up until Chameleon supports the chip or someone can offer some better advice as to what to do.

I made some progress.  I used the Pandoras Box beta 2 tool to create the installer using DP4 Mavericks. Once that's done, I replace the following Kexts from the http://rampagedev.wordpress.com unified 10.9 DMG:

 

/S/L/E/:

 

FakeSMC.kext

AppleIntelCPUPowerManagement.kext

GenericUSBXHCI.kext

AppleIntelE1000e.kext

VoodooTSCSync.kext (added later, doesn't make a difference)

 

I edit /Extra/org.chameleon.boot.plist with the following boot flags:

 

-v PCIRootUID=0 npci=0x3000 cpus=1

 

I run the installer and it recognizes the CPU and starts loading kexts.  However it gets caught on a Looking for Root Device error.

 

See this video:

 

 

So this is progress.  I feel like I'm close to getting into the installer.  But I've played around with a number of kexts and had no luck.  Any ideas?

Try -f and -x flags too

Following these steps, I am able to get all the way through to chameleon mounting the installer on root device, but then I crash:

 

1.  Run Pandora Installer selecting Mavericks, Mac Pro 3,1 on an external eSata hard drive

2.  Using Unified DMG from RampageDev.wordpress.com, I replace AppleIntelCPUPowerManagement.kext, FakeSMC.kext, AppleIntelE1000e.kext

 

Boot with flags:

 

-v npci=0x2000 PCIRootUID=0 cpus=1

 

 

It hangs there.  Another fellow (http://www.insanelym...-atom-yes-atom/) was able to get just as far on an Atom computer, but it hangs there.

 

Given that, I do not think the Mavericks kernel yet supports Ivy Bridge-E.  That's my guess. 

 

To that end, I replaced mach_kernel with the version from DP7 (which has some power management stuff for X79 that other builds don't) and replaced the AppleIntelCPUPowerManagement kext for that version from the RampageDev repo and I got stopped at the same thing.

 

I'm quitting until anyone else has some better ideas.

I'm in a similar boat with an EVGA X79 Dark and 4930k. I've been attempting to use Clover and haven't yet gotten past "Loading drivers".

I'll make a mountain lion installer using the above methods and give it a try.

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.

Edit
Booted by adding DSDT=No flag !!
