hangs at grey apple logo

[lemarqq]

I tried again to install ML, but it hangs at grey apple logo. I checked my HCL, it's okay.

My mobo is Gigabyte GA EX58 UD5 / Intel I7 920 / GTX 660 / No overclock at all.

I unplugged the Logitech gamepad, webcam, sound jack, etc. I modified everything in BIOS, step by step. No luck

And i don't know how to see the error / kernel panic ( if any )

All i see is " press any key to start the instalation" ( something like this ) and when i press a key, i do not have any option to edit / to type " -v " etc

Would you help me, please ? Every advices / suggestions / are welcome.

Thanks in advance

PS : I forgot to mention, my keyboard is PS2, and the mouse is USB

Could that be a serious reason ?

hummm, keyboard PS2 need a kexts for work and you can not use for install, use a Keyboard USB, boot with -v and post a photo, what method do you use for install?

[lemarqq]

I dont know what method i used.

Do you mean what dvd / distro i used ?

Hold on a second : so, do you mean, i need to have the keyboard with USB ? Are you sure 100 % ? SATA Port 0-3 Native Mode must be ENABLED or DISBLED ?

Thanks a million.

if you USE Methodo USBInstaller or DVInstaller, with USBInstaller you can add kext for your keyboard, but if DVD not have the kext for your PS2, how will you do it ?

[lemarqq]

Ok, and how can i add with USBInstaller the kext for PS2 ?

[iFIRE]

Put this two kexts in System/Library/Extensions of your USBInstaller, and boot with -f -v GraphicsEnabler=No npci=0x2000

I sent you an pm, iFIRE.

Thank you very much

[iFIRE]

Please!!! post your doubt and problems here in your topic, don´t PM please, this can be your graphics kexts for your NVDIA, try delete all NVDA kexts from your USBInstaller and boot with the boot flag what I post above

[lemarqq]

I install it right now

And i will have to check / uncheck there, but i will do it carefully

One question : when everything is done, can / do i have to / change back in BIOS , the option from Power Management - 64 bit to 32 bit ? I ask that because i usw Windows 7 Ultimate, too.

Will this option affect Windows, if i leave it as 64 bit ?

this is a kext ApplePoliceControl.kext, go for /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/ApplePolicyControl.kext and delete this kext

[lemarqq]

I can't get to desktop

Any other way to delete this ??

Thank you

[iFIRE]

yes, boot with -s

 

mount /

cd System/Library/Extensions

rm -rf

AppleGraphicsControl.kext/Contents/PlugIns/ApplePolicyControl.kext

cd System/Library/Caches

rm -rf *

reboot -R lnk
