Yosemite Installation - Blackscreen and nVidia Rom Patching failed

[Danielkng]

OK. I will try. When i want back to my Intel, i must "reset" the bootplist?
To the Standard Code i mean.

Good luck on this one...

good luck (in security for you save your bootplist original )

 

[Danielkng]

Yes, i have.
Intel: 2 - 5 Minutes Blackscreen.
nVidia: Starts with Intel (-v says, intel HD 3000), Blackscreen ~ 3 Minutes
nvidia: GraphicsEnabler=Yes, Nvidia could not patched. System Halted.

 

[gtpc]

ok you try GraphicsEnabler=no with intel and nvidia ? or just intel?

 

[gtpc]

ok if my Boot.plist does not work on your map intel or nvidia, then I leave the room for more experienced people. Because my knowledge is not high

 

[Danielkng]

GraphicsEnabler=No -Nvidia.
But with no bootflags, it dont Boot too.

With Intel, i got a blackscreen too... :/

What kind of options do you have in BIOS for the integrated intel graphics? Assuming default org.chameleon.Boot.plist provided with Unibeast, try flags:

dart=0 nv_disable=1 cpus=1 -v

Make sure your USB is an 8GB USB2 stick. Make sure you created your USB with "Laptop Support"

Remove /Extra/Extensions/AppleACPIPlatorm.kext
Update /Extra/Extensions/VoodooPS2Controller.kext: https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller
Add /Extra/Extensions/GenericUSBXHCI.kext: https://github.com/RehabMan/OS-X-Generic-USB3

Is your screen really 1366x720? That is a bit of an odd resolution...

For integrated.. Nothing. Just choose from Intel to nvidia.
My Bootmedium is a Harddrive with a 9GB Partition.
Seems to work... Because i came into the Bootloader.

Bootflags: Edit in the bootplist, or just type into the Bootloader?

For BIOS settings, See my dropbox.

Not necessarily. Show photo.

Typing is an easier way to try different ones.
