I successfully ran your 10.9.2 install image in safe mode on this build:
Intel 4670K / HD4600 GFX (No Discrete GFX Card)
I successfully upgraded to 10.9.4, after applying a powermanagement
patch specific to this processor, and creating an SSDT using Chameleon
Wizard... (Based on Mac Pro 14,2) System was running stable with no bootflags necessary.
After an accidental upgrade to 10.9.5, I can no longer boot into the system
with safe mode, verbose mode, cache ignored, etc.
I am trying to run a 10.9.5 installer, but I get several kernel panics with different flags,
BSD process name corresponding to current thread: kextd
Also BluetoothHCIControllerTransport message, or DRM Status, etc.
I've gone into this installer image and replaced its mach_kernel with yours for haswell
processors, still to no avail...
Am I missing something? I have never been able to boot in clover, but chameleon is
providing me with these errors.
Thanks for your time
