williamvinzant Posted May 5, 2016 Share Posted May 5, 2016 What sys def are you using? MP 6,1??? Link to comment Share on other sites More sharing options...
0000-1248 Posted May 5, 2016 Share Posted May 5, 2016 Make sure that you're booting with nvda_drv=1 and that you have the correct Web Drivers installed for your build of Mac OS X (not your version, but the actual build). Also make sure that nv_disable=1 hasn't crept into your config. Hope I could help, - Matt Link to comment Share on other sites More sharing options...
stinga11 Posted May 5, 2016 Author Share Posted May 5, 2016 I use MacPro6,1 but I don't have problem with the GTX 780 and nvidia web driver. Link to comment Share on other sites More sharing options...
Dwarfy Posted May 5, 2016 Share Posted May 5, 2016 I use MacPro6,1 but I don't have problem with the GTX 780 and nvidia web driver. You need AGDPfix for MacPro6,1. you can either do it manually or use Shilohhh's app. Here is AGDPfix App. Link to comment Share on other sites More sharing options...
williamvinzant Posted May 5, 2016 Share Posted May 5, 2016 Should do the trick! Link to comment Share on other sites More sharing options...
stinga11 Posted May 5, 2016 Author Share Posted May 5, 2016 Guys thank you, But I've done everything. Believe me when I say that the video card I had was not compatible with Mac. I need someone who has a Nvidia GTX 970 running in 10.11.4 and tell me which model he uses. Link to comment Share on other sites More sharing options...
williamvinzant Posted May 6, 2016 Share Posted May 6, 2016 I use EVGA and it works flawlessly after agdpfix with mp 6,1 sys def in 10.11.4 What would happen when you tried to boot with the Gigabyte card? Log errors? 1 Link to comment Share on other sites More sharing options...

Log errors? The monitor turn off but I did the agdpfix and tried with other definition iMac14,2 iMac13,2 iMac12,2 MacPro3,1. I tried with all output and nothing.

williamvinzant Posted May 6, 2016 Share Posted May 6, 2016 Can you boot with nv_disable=1 or -x and get to desktop? Link to comment Share on other sites More sharing options...
Dwarfy Posted May 6, 2016 Share Posted May 6, 2016 Evga usually got reference cards, while gigabyte doesn't. As far as I know. Reference cards should work. 1 Link to comment Share on other sites More sharing options...
stinga11 Posted May 6, 2016 Author Share Posted May 6, 2016 Can you boot with nv_disable=1 or -x and get to desktop? Yes, with nv_disable=1 boot Link to comment Share on other sites More sharing options...
williamvinzant Posted May 6, 2016 Share Posted May 6, 2016 Once you're at desktop you can try to uninstall Nvidia web driver, change back to mp 6,1 sys def, reboot with nv_disable=1, reinstall correct Nvidia web driver then reboot once more with nv_disable=1, reapply agdpfix then reboot finally with nvda_drv=1 -f -v in that order let us know if it works!

Yes I did. I tried with a clean installation too and anything works. I think it's like Dwarfy says, the problem is that the Gigabyte card of my friend does not use the reference PCB.

williamvinzant Posted May 6, 2016 Share Posted May 6, 2016 Dwarfy I think is right too was just a thought you could try. The EVGA does work though if you want to go with it. Good luck on your upgrade! 2 Link to comment Share on other sites More sharing options...

TizzyD Posted May 11, 2016 Share Posted May 11, 2016 I've got the GTX 970, and I have found instability in some of the Adobe apps that use the GPU extensively. Both Photoshop and Lightroom can generate a complete crash of the OS, using either the Apple or nVidia Web drivers. Turning off the GPU accelerator does not address the crash completely. There's clearly a buffer overflow or some other deep nasty going on, but I'm not a kernel developer, so I can't (yet!) determine where the issue actually resides. This issue is currently causing some major issues, and it's something I've got to figure out. BTW--both 10.10 and 10.11 exhibit the issue. So, YMMV. 1 Link to comment Share on other sites More sharing options...

Some say AMD cards work better with OS X, because apple uses it more. Link to comment Share on other sites More sharing options...
