I installed hachkintosh 10.8.2 ML on my samsung laptop. NP550P5C
its ivy bridge, i have Nvidia GT650M and Intel HD 4000
all im trying is to get my HD 4000 working. I searched a lottt and read many guides and even saw afew successfull installation on same model of samsung laptop.
(however they are not same in specs)
Unfortunately I was not able to make it working, two times i got scrambled and noisy screen and mouse and keyboard disabled entierly!
one time i got black screen, and so...
Actually i alittle confused , because there are many different suggestions out there and im not sure which one is the best.
for example some say to put EFI string in deviceproperties , some say to change DSDT, some say to put some strange key and value in boot plist ,......
I really appreciate if someone can help me alittle. maybe its helpful for others too as i think i mixed different approaches.
Here is my situation : After installing and reboot, i had to remove Gforce..kext and all nvidia kext files and also all HD3000*.kext and HD400*.kext files to prevent my mac freezing.
Now, here is my questions :
1-Which kext files are exactly required to get my HD4000 working? do i need to copy HD4000*.kext back?
and what about framebuffer capri ? do i need to put original files back and try to make it working by putting different EFI strings?
2-how many different approaches exists for this problem?
3-I tried to use this driver http://www.osx86.net..._ml_driver.html but it made my keyboard and mouse freezing
4-How can i make a correct EFI string without using the ready ones i can found on internet?
And my real question :
5-At the moment, i canboot my mac in normal mode and i dont have HD4000*.kext files installed. whats the next steps to enable my graphic?
I greately appreciate if someone can help me to solve this problem.
let me know if have to provide more information.
