Recommended Posts

Hei i am new to this forum and this is the probleme i have right now.

i have managed to install mac os x lion (iATKOS_L1)

on my HP ENVY 17" 3D with

intel i7 core 1.6 Ghz

8 GB of RAM 1333 MHz DDR3

ATI RADEON HD 5800 series with 1 GB RAM

1.75 TB HDD (750 GB for win 7, win 8, and Ubuntu 12.04 TLS and 1 TB for MY DOCUMENTS)


i installed mac OS X on a 160 GB USB external HDD (with 3 Partitions: mac os x, my documents, Data(ntfs))

My build in display is a 3D enable display.

i used rboot with the option cpus=1 -v to install and star Mac OS X


everythings works (not the wifi and the synaptics touch mouse) but all the rest like webcam, USB port, bluetooth, Hard drive, dvd drive, sound, sd card,keyboard...tec


I use BCD edit to manager all 4 OS boot.


when i star mac OS and it comes to the logg on screen, the built in display goes black and the screen only comes on my hdmi wich is connected to my samsung tv. even when i unplug the hdmi cable my buit in display stays black or not even turned on.

please i need help. thanks for your help in advance.
