Hi, can I ask which PCI-E Bluetooth/WiFi card you bought and if you ever upgraded / installed High Sierra 10.13.2 with everything working OK re USB / Audio etc? Thanks//Zztony

Dell T7500, 2 x W5580 Xeon @ 3.20GHz, 24GB 3-ch ECC RAM, GeForce8600GT512 and AMD Radeon 7870 GHz Edtn. cheers//Zztony

Sorry for the late reply.....Yes, it's the original mach_kernel. Any suggestion on what to do next for me to investigate further? Still stuck with the same problem.... thanks//zztony

I downloaded Chameleon-2.2svn-r2149.pkg and installed it with the kernelpatcher selected, but it hangs with: Patching 64bit XNU Kernel 0.0.0. Please see attached pic. thanks//zztony

Picture of KP / boot error message thanks//zztony

Still no luck with booting the 2cpu rig, panic during boot with a swift reboot. No chance to take a pic of the panic-error-message, but managed to film it with my FlipCam and snipped some screenshots from it(sorry for the bad quality) thanks//zztony

Made a myHack USB boot with 10.8.2 and installed to a new partition. First(initial) boot OK to new installed partition. Added the Extra from you, fixed permissions and it booted nicely(as before) with one cpu installed. NEXT: will install second cpu and try again.... thanks//zztony

Here's my ioreg file also... IOService-MacPro.zip

I ran the Darwindumper with only 1 cpu installed and attached are the output in zip file and the content of my Extra folder. thanks//zztony DarwinDumper_2.4.9_chimera (chameleon, stolen and rebranded)_1.5_ML_zztony.zip Extra.zip

This a photo of a USB boot from the older i.P.o.r.t.a.b.l.e (10.0.0) with the default 'chocolate' kernel, at least it stopped when it KP so I was able to take a pic of it.

Added to Skype! Not possible to nothing with 2cpu's installed, but I have a clean install based on unifail/Easybeast with only cpu installed that work just fine. It's not as easy to get a clean install with myHack unfortunately.... Thanks//Zztony

Hi, I have a Dell Precision Workstation T7500 with 2 Quad-Core 'westmere' Xeon [email protected] and 12GB ECC RAM installed. I got it up&running very smoothly with unifail - Install 10.8.2 - multifail = OK! BUT, It seems impossible for me to even boot OSX with both CPU's installed, I've tried any version.(tried 10.5.x/10.6.x/10.7.x/10.8.x) What do I need to do to boot this system with both CPU's installed? KP error and instant reboot every time, very hard to be quick enough to record or take a pic of it..... Any ideas or suggestions? Cheers//Zztony

Yes, but no luck

1. NO DSTS p.t., will try to install without DSDT first, then work my way towards C&P-States, generation of these and sleepmode & restart when rig at least boots ands are stable. 2. Most KP´s are related to ACPI, IOPCI and PowerMngmt stuff. 3. Attached 2 of those.... Thanks, //Ztony

Tried already cpus=1 -f -x Also pmVersion=0 and a lot of other params but no luck. Will upload some pictures of KP Codes soon. Thanks, //Zztony

Hello everyone, I have some problems installing Lion on my Dell Precision T7500 with 2 quad core Intel Xeon W5580. I´ve installed a lot of Latitude´s and other hackintosh´s over the years, but all have been single cpu´s. Tryed all different bootloaders and boot-parameters, but no luck, KP every time though different codes a lot of them are related to power mngmt. Anyone done this success on a dual quad core rig? Cheers, //Zztony
