[SOLVED] NVIDIA GeForce GTX 260 + Sierra

[serianox]

Got the nvidia card to work, The only thing that's missing is audio, I have the same motherboard as you do DarkMessiah ASUS P6T , previously I only needed to select reaktek ALC888 legacy on multibeast but it's not working now. Could you please tell me how you got the audio to work? Thanks a lot!

Hi guys,
I have the same problem above but I can't even start the installation process because of kernel panic related to NVDAStartup.
I can't start with nv_disable=1
Do you have suggestions ?

Please check "nv_disable=1" AND "InjectNvidia=false".
"nv_disable=1" and "InjectNvidia=true", I got KP.

Thank you, that did the trick! Sierra got installed!
I still have some problems getting it to work with the full resolution of my monitor, but at least I can reach the homepage.

I used the kext attached to your post. and i used the bootflags: "slide=0 dart=0 npci=0x2000 kext-dev-mode=1 rootless=0" (selecting the InjectNvidia option under graphics in clover). Now i don't get a KP anymore, but the screen stays black. Did i miss something?

EDIT: I got it to work!

My steps:
1. Install Mac OS Sierra
2. Boot with nv_disable=1
3. Download and install the kext yhiraki provided earlier in this thread through Kextbeast
4. Change bootflags to "dart=0 PCIRootUID=0 GraphicsEnabler = Yes darkwake=0 rootless=0"
5. Reboot
6. Profit $$$

I have no sound now, It used to work with ALC888 legacy on El Capitan but it's not working on Sierra. You have my same motherboard, is sound working for you? What did you do to make it work? thanks!!

Now I found solution! My GTX 260 works fine on Sierra

The solution: Use NVDAStartup.kext for El Capitan.

If you have any backup including TimeMachine, you can get NVDAStartup version 10.10.13 in S/L/E.
If you have no backup, you can use the one I attached in this post.

1. Backup and remove NVDAStartup.kext
2. Install NVDAStartup.kext for El Capitan with KextBeast or something.
3. Reboot with 'InjectNvidia=true'
4. Enjoy your sierra world!!

I think its not best solution. I hope someone find better one.

Thanks yhiraki, your trick worked for me.

I didn't even get a chance to install Sierra. It would just panic ⅔ through booting into the installer. In the end I've sacrificed the GTX260 and lashed out $40 on a GT710 to see what would happen. Works marvellously. Now to wait for drivers for the newer cards that have more grunt.
