Yosemite Installation - Blackscreen and nVidia Rom Patching failed

[Danielkng]

Hello

Today i have download Yosemite from the Appstore.
So, i have started from my USB and click enter. The Apple-Logo appears, after ~2 Minutes i have got a blackscreen.

2rd try: GraphicsEnabler=Yes. After 2 Seconds ive got another Error. nVidia Rom patching failed. System halted!!!

3rd try: GarphicsEnabler=No -v. The Script appears. After ~3 Minutes "Done", but then... Blackscreen.

4rd try: -v -x. Script starts. Blackscreen.

My laptop:

Intel i5-2450M @ 2.50Ghz
nVidia 610M 1GB VRam
6GB Ram

My Question is: Does Yosemite not work? Or have i made something wrong?

Sorry for my bad English, im German

Does your laptop have only nvidia or nvidia+intel (optimus)?

 

[Danielkng]

It has the Intel Graphic and the nVidia Optimus.

It has the Intel Graphic and the nVidia Optimus.

Note: GarphicsEnabler is not a valid bootflag... it is GraphicsEnabler.

Use bootflags:
dart=0 nv_disable=1 -v

Please update your profile to reflect your hardware...

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Read post #4 carefully... "in your profile"

Also, the discrete graphics capability in a switched dual-GPU configuration are not supported with OS X on hacks.

My Profile is Edited

In my BIOS i have from "Internal" to "Switchable" set. (Baaaad English...)
So, will it work?

nvidia will not work. Intel will work in either scenario.

 

[Danielkng]

nvidia will not work. Intel will work in either scenario.

So, i have to switch to "Internal"?

No. What part of 'either scenario' did you not understand.
