Ok, I've managed to install OSX 10.8.4 on my Dell Inspiron 15R SE but have bunch of problems enabling GPU.
Without any mods OS boots with GraphicsEnabler=No card and hangs on AppleIntelFrameBuffer with GraphicsEnabler=Yes
What I've done:
- Installed Intel HD Graphics kexts for 10.8.4 - tried to boot with GraphicsEnabler on and off, system hanged on loading AppleIntelFrameBuffer
- injected device-properties - hanged on loading AppleIntelSNBGraphicsFB
I'm not able to disable Radeon card from BIOS, also think wrong AppleIntelFrameBuffer.kext might be a problem...
