After installing Nvidia Web drivers El Capitan results in boot failure with no kernel panic or any sort of error message

[whou1964]

Hello!

I am trying to upgrade Yosemite 10.10.4 to El Capitan 10.11.1 with no luck. 

I've been using hackintosh for quite a while now. I've never experienced any difficulties with upgrading to newer version until recently.

The installation process goes all well with no problems as well as the first boot. I'm able to run all post-installation procedures (install clover bootloader, run unib... etc.). The problem begins when I install the latest Nvidia Web drivers. The Hackintosh just won't boot up and it keeps auto-restarting just before it shows the login screen (screen goes black for a few seconds and then the pc restarts). There is no kernel panic also booting in verbose mode does not show anything unusual (the web drivers seem to start up correctly). Sometimes what I am able to read out is: "previous shutdown cause: 5" but I'm not sure if this is related to a boot failure or to a previous "normal" shutdown.

 

I've tried all sorts of things to resolve this issue from trying different combination of boot flags to deleting and reinstalling the nvidia drivers, booting into safe-mode / without kernel cache. I tried to inject Nvidia Gfx via clover bootloader but this resulted in kernel panic. The only thing that partly helped was booting with nv_disable=1 flag but then the resolution is really bad and hackintosh is practically unusable (the screen blinks to every frame when animation is being shown).

 

Could you please help me with some suggestions how to fix this issue.

 

 

 

My Hardware:

Cpu: i7

Motherboard: dx58so2

Gpu: Nvidia GeForce 285 GTX

Custom DSDT: Yes

Flags that I've used: nv_disable=1/0, nvda_drv=1/0, GraphicsEnabler=Yes/no, x,  npci=0x2000/0x3000, cpus=1/2/3/4, IGPEnabler=Yes,  dart=0 kext-dev-mode=1, PCIRootUID=1

 

PS: Maybe I should also mention that I was previous using the Chimera bootloader instead of clover. Unfortunately I cannot post any boot logs because there is no log in /var/logs or /L/Logs, /S/L/Logs

Have you tried using injectnvidia without the webdrivers? and did  you mean clover as your bootloader?

Yes I have and the resolution is really bad. The screen flashes to every animation frame it has to refresh. I had no such problem previous to the El Capitan.

 

Sorry, for the bootloader I meant clover.

Hello, I have faced just the same issue. Have you managed to fix it? I was trying to uninstall nVidia web drivers but I can't find them installed on HDD. Only thing nVidia related I could find is that Settings extension (which don't work anyway)
