10.9.5 Mach_Kernel Patched (After mach_kernel for Security Update 2015-005 1.0) For Intel Z87 Haswell Motherboards


About This File

This is a patched version of an official vanilla mach_kernel from Mavericks 10.9.5 after Security Update 2015-005 1.0, allowing Z87 Haswell motherboards with reboot loops or kernel panics capable of booting.

The following perl scripts have been applied to the vanilla mach_kernel for 10.9.5 after Security Update 2015-005 1.0:

#1

perl -pi -e 's|\x74\x6c(\x48\x83\xc7\x28\x90\x8b\x05..\x5e\x00\x85\x47\xdc)\x74\x54(\x8b\x4f\xd8\x45\x85\xc0\x74\x08\x44\x39\xc1\x44\x89\xc1)\x75\x44(\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x57\xf8\x48\x8b\x47\xe8\x48\x85\xc0\x74\x06\x48\xf7\xd0\x48\x21\xc2\x48\x0b\x57\xf0\x49\x89\xd1\x49\xc1\xe9\x20\x89\xd0\x8b\x4f\xd8\x4c\x89\xca)(\x0f\x30\x8b\x4f\xd8\x0f\x32\x89\xc0\x48\xc1\xe2\x20\x48\x09\xc2\x48\x89\x17\x48\x83\xc7\x30\xff\xce)\x75\x99(\x5d\xc3)\x90{7}|\x74\x73${1}\x74\x5b${2}\x75\x4b${3}\x66\x81\xf9\xe2\x00\x74\x02${4}\x75\x92${5}|g' mach_kernel

#2

perl -pi -e 's|(\x25\x1c\x00\x00\x00\x48\x8d\x0d..\x5e\x00\x3b\x01)\x74(\x11\x48\x8d\x3d...\x00\x44)|${1}\xeb${2}|g' mach_kernel

I take no credit for the creation of the perl scripts used.

 

Patches #1 & #2 have been documented on this blog by the original owner here. Shout outs to Pike R. Alpha whose code the patches are based on, he lives here.

 

Tested on EVGA Z87 FTW

 

Please let me know if it works well for you so I can confirm the amount of success users are having. Thanks
