Can't install Yosemite 10.10/01 on my Haswell-e GTX 970 System

[noname1991]

Hey guys,


first of all sorry for my bad english. I'll try to explain it in a short way.


I've build a gaming and video editing machine by myself. The components are:


MSI Gaming 7 X99S Motherboard with latest BIOS version 17.5
MSI GTX 970 4G Graphics Card
Intel Core i7 5820k (normally @ 3,3 ghz)
Samsung EVO 120 GB SSD (For Yosemite)
Samsung EVO 250 GB SSD (For WIN)
Corsair AX860i Power Supply
Asus BW-16D1HT


I've tried to install Yosemite as subscribed in these installation guides:

http://www.tonymacx86.com/yosemite-...motherboard-temporary-guide-os-x-10-10-a.html


The moment where the system turns in a black screen is after [IOBluetoothHCIController][start] -- completed, which means the GUI cant load cause of the NVIDIA driver. The haswell e 5820K CPU hasn't any internal graphics. So I cant reach the installer with IGPEnabler=Yes GraphicsEnabler=No.


Today I tried it with the new 10.10.1 Version (should include the NVIDIA Alternate Graphics Drivers for GTX970)
But the Graphic Card is directly unknown from boot as before. It only shows unkown 2989MB NV124 in verbose mode and GraphicsEnabler=Yes.


The GTX 970 is running under windows and is 100% functionally, tried far cry 4,...


So pleeeeeaaaase, can someone out there help me???????

Use a supported card to do the install, install web drivers, and reinstall the 970...

Thanks for your fast reply

get installation done with geforce 8800gts. After install OS X and nvidia WebDriver-343.01.01f03 the system can boot with my MSI GTX 970 but graphic card is unknown as before. If select OS X driver in Nvidia Panel the system doesn't boot. It only works with Nvidia driver.

Can you explain it to me why my GTX970 can't load???

Please have a look at the screenshots
