Mountain Lion 10.8.3 On Lenovo G580 i5 HD4000

Update for Mavericks 10.9.2 and install Dual boot for HD4000 with-without MAC –

These days, most of new laptops are installed with Intel 3rd generation i’s series – Lenovo came out with a low budget $448 G580 i5 3230M with 4GB Ram and 500GB of hard drive. We install Mac OS X Mountain Lion 10.8.3 (newest version at this time) – Everything seems to work fine except Elantechs trackpad that’s not as smooth as Synaptics and the SD card from realtek 0129 doesn’t work.

Most of new laptop these days are UEFI for windows 8 to boot faster – Dual boot became very hard to do – The best is to boot from the bios when we want to access Mountain Lion.

Device-properties for HD4000 needed for graphics to work.
