Hi friends,
After a whole day struggling to install, I finally made it!
Well, almost everything is working.
I use an USB Mountain Lion disk to install (myHack method) but the bootpack from OSX Latitude didn't work.
I had to boot to USB with the following flags:
PCIRootUID=1 -x -v This was the only flags which worked.
As I already knew I wouldn't have internet connection I placed multifail inside a folder on the USB installer.
So I have checked:
EasyBeast Drivers > Graphics > NVIDIA Fermi > OpenCL Patch > NVIDIA Retail 304.00 (this one gives me full resolution!) Ev0reboot FakeSMC v5.1.61 FakeSMC v5.1.61 Plugins PS/2 Keyboard/Mice and Trackpad USB 3.0 System > AppleACPIPlatform Rollback > 10.8.1 Rollback System > Patched AppleIntelCPUPowerManagement > OS X 10.8.x Customization > Boot Options > PCI Root ID Fix Customization > Boot Options > Verbose Mode (I like it) Customization > SSDT Options > Sandy Bridge Core i7 (to match my processor)
At BIOS, I left enabled the Discrete Mode (this enables Nvidia GPU), AHCI mode, Legacy.
Now, almost everything is working but wireless, had to buy a card for that., probably Dell 1510.
