Help with Mac OSX 10.8.2 installation on Envy 17 1188-el

Recommended Posts

Hi guys.

i'm trying to install Mountain Lion 10.8.2 on HP Envy 17 1188-el.

I've encountered many problems with clean retail install, so i've tried with iAtkos Ml2 and it work... but not all, it's just a very basic system without

many features.


I've tried also different bootloaders, kexts and utility... without success.


Who can help me? I've darwindumper reports, are useful?



CPU: Intel Core i7-720QM da 1,6 GHz

GPU: ATI Mobility Radeon HD 5850 1024mb

RAM: 6 gb ddr3 1333mhz



What work:

CPU

Memorycard reader

2x USB 2.0

Keyboard & Trackpad

Backlight of keyboard

DVD Drive


Not working:

Video (only with ATY_Init, without acceleration, many glitches and generic info in System Profiler [ex. only 7mb of memory recognized)

1x USB 3.0

WiFi (i'm planning to change it)

Bluetooth


Here's a SystemInfo screen:

 

I hope there is a solution. :?


Thanks in advance to all. :D



ps. Sorry for my english. :roll:

I know i have to try many times... and it's a probably hard work. But it's ok.


Anyway, i've tried to edit the ATI5000Controller, but i saw that there is my video card's device id and vendor id (0x68A11002) already.


I've updated Chameleon to the last release "official". (and tried also with Enoch version)

I've tried to apply the DSDT patches (Nahelm)

I've searched my device id on the kexts section of Olarila... and found many entries. Seem to be compatible, but i don't understand where i made a mistake.

Is there a way to identify the origin of the problems?


Thank you in advance.

So i need to edit the other kexts also?


I have to:


- set framebuffer (Nomascus for this card)

- Edit these kexts

- Set GraphicsEnabler to Yes


Right?

The DSDT's patches for Nahelm are universal? (for every notebook\desktop)



Thanks.
