n810 Posted July 21, 2014 Share Posted July 21, 2014 I have an Intel i5-4200M CPU and from what I've been told, it is a haswell processor so it will reboot before going into any Mac installation (tried distros, vanilla, etc.) and each have required boot args such as "hp" or "haswell" or "xpcm-free" to boot into the installation. Otherwise, it instantly reboots before going into the installation from the bootloader. I made a bootable USB using Pandora but I'm having this issue again where I cannot load the installation. Does anyone know what I can do for this? Is there a file I need to add or is there a boot arg already designed for this by default?

Is it working for Mavericks 10.9.x only ? Can it be applied for Yosemite DPx's /System/Library/Kernels/kernel too ?
