Nvidia GeForce GT430 Yosemite

Hi I'm trying to get my GeForce gt430 to work with my Yosemite install and I cant seem to get it to work. I've tried using a guide to get it working in DP1 But it didn't work. I've tried with the boot flags GraphicsEnabler=Yes, GraphicsEnabler=No, and PICRootUID=1 and they all just cause a black screen. I posted a picture of what verbose mode says before the screen goes black. Also I have installed the latest cuda (9/19/14 release) and the latest Nvidia web drivers

Does anyone else have this card and have it working?

Try this flag:

nv_disable=1

I have Nvidia GF 435m 2GB graphic card in my Dell laptop and everything was working in Mavericks however when I tried to install Yosemite I was getting the same issue with boot. I tried all commands and fixes but noting worked. I knew that much its due to the graphic card so I used Vmware to open my Yosemite boot USB and deleted the all (7) NVidia kexts from Extensions folder and volla this time everything boots fine "but in very low graphcs".....

Now I have everything running (sound, wifi, bluetooth etc) except graphic card and I have no idea how to get i fixed.

I also found this solution which I still need to try....maybe you can give it a first shot? Please note after updating the info you need to re install the nvidia kexts which you removed and then make sure to fix your HD permissions.

add the following to - /S*/L*/E*/AppleGraphicsControl.kext/C*/P*/AppleGraphicsDevicePolicy.kext/C*/Info.plist

Code:
<key>ConfigMap</key>
<dict>
<key>Mac-F60DEB81FF30ACF6</key>
<string>none</string>
</dict>

Well that solved the black screen problem but there is no acceleration and the card is listed as NVIDIA Chip Model 3 MB. Any other suggestions?

Go through the installer with that flag, once it's complete then try booting without it.

Anyone got this working please...?

I did actually. I have Acer 5742G laptop with Nvidia GT 420M and couple of hours lost trying to install Yosemite with clover usb boot. At the end everything works as it worked in Mavericks with LOADVBIOS in graphics driver section in clover configurator and having your graphic card vbios in Efi/CLover/ROM named as 10de_xxxx.

Thats a good news if you got this working, as I'm not that good in this can you please let me know steps how to do this? Many thanks in advance.
