How to Install ML on your HP Pro 3500 MT


Recommended Posts

Hello guys !

got finally Mountain Lion installed on my HP Pro 3500 MT. So I'm gonna do a quick guide about how to install it !


Specs :

i5 3470 @3,20Ghz


Intel HD Graphics ( I have installed a nVidia GeForce 620 GT Instead )

Step 1 :

Make the Bootable USB Stick : http://Olarila.com/forum/viewtopic.php?f=27&t=3101

IMPORTANT : Don't remove any kext from the USB Stick , You will need to boot with -x to reach the installer, once the installation is done , boot this time from the HDD where you installed your system again with -x

Step 2 :

the system now is in your HDD , you will need now multishit to install the Chimera's bootloader & the SMBios of the last iMac 13,2 , once it's done download kext utility & some kexts( below ) and install them , in order to boot without any command flag.

You will notice that Graphics are already enabled ( Works with 620 GT in all the ways ) if not , for the Intel HD Graphics , use this : http://www.insanelymac.com/forum/topic/287668-guide-intel-hd2500-full-resolution-and-qeci-1083/

IMPORTANT : if you don't boot from the usb stick, you may have the boot0 : error , this is how to fix it http://Olarila.com/forum/viewtopic.php?f=27&t=1676

AUDIO : for the audio : you'll have to remove AppleHDA and Use VoodooHDA and inject the informations concerning the DevID & VenID as explained in this tutorial : http://Olarila.com/forum/viewtopic.php?f=28&t=454


PS : I don't use the Ethernet, I use an USB Dongle.


ENJOY ! and I hope that it will be moved to Guides topic, thanks a lot for your help Olarila , you're awesome
