Data/stack execution not permitted: xpcd[pid 126]

[GingerBraFace]

I have been getting an error when trying to install Mavericks 10.9.2 or 10.9.3 (10.9.1 works fine). The error "Data/stack execution not permitted: xpcd[pid 126]" repeats after attempting to mount the volume that has the previous (10.9.1) installation on.

I have tried:

• Changing the permissions for the drive I'm using to install
• Different kernels.

Thanks for any help in advance

 

EDIT: Forgot to mention, I'm using an FX9590 and GTX 760.

Hi. May be try this : http://www.osx86.net/files/file/4050-amd-mavericks-1093-kernel/ . (works only for 10.9.3 not 10.9.1 or 10.9.2)

 

Copy "mach_kernel" to Hard disk's root.

 

Copy contents Kext folder to /system/library/extension

 

Hope it's useful.
