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

[Shikoo]

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:

Hi, Thank you for your reply.

I've tried with these guide, but nothing changed. The graphic still not work.

My errors or hard hardware configuration?

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.

hello

to ati works in 10.8.x

like the post say is not only need the

ati5000controller

also must be loaded

atisupport

amdradeonacellerator

and perhaps u must use framebuffer

so must be loaded also atiframebuffer

if u want a prepared kext or solution, must google for it.. by u note specs...

good hack

[Shikoo]

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.
