You do realize that nv_disable=1 means you're running with software rendering, right? It's expected that this will be very slow, but the whole point is that it'll let you boot the machine and install the latest web drivers. Once you've installed the web drivers for the OS, you can switch from nv_disable=1 to nvda_drv=1 to enable the web drivers and get full acceleration.

As to why it's not working for you, I have no idea. What system are you using? What exact OS version and web driver version?


its a P8P67 Asus main board, 10.10.1 and 10.10.4. Web drivers were new. Asus GTX 750 2 GB GDDR5.
If I boot with nvda_drv=1 then either stuck on apple boot or signal lost. I don't have onboard graphics.

thanks for answers!
Choosing MacPro 3.1, installing latest Webdrivers somehow made it work, don't ask me why and how :) Enjoying for the moment

StoneJack,
Would you please list, from start to finish, the steps you took to successfully update from 10.10.3 to 10.10.4 with the GTX 750 installed?

For future reference, you probably want to go to one of the various Hackintosh forums for help with this.

StoneJack,
Would you please list, from start to finish, the steps you took to successfully update from 10.10.3 to 10.10.4 with the GTX 750 installed?

I had to reinstall Yosemite;
boot with nv_disable=1
never installed any CUDA drivers as I thought they were useless
first updated the Yosemite to 10.10.3, tried the web drivers, no go.
then updated to 10.10.4, installed the new web drivers 346.01.03f01
rebooted with web drivers nvda_drv=1
was on official drivers; but had the control panel in menu bar;
from there I chose again web drivers and rebooted and it was it.
it was native supported.

I did it while I had installed GTX750Ti, I got one GTX750 1Gb exchanged for GTX750Ti OC 2Gb.
I didn't test with GTX 750; that card will go to Windows PC.

Thanks for your reply.

So, to boot to the desktop with the Maxwell GPU installed, you entered the nv_disable=1 boot flag?

I've got a GTX 750 to install, and I want to be sure I understand the procedure for updating to 10.10.4. That means knowing how to reach the desktop after the update so that the web drivers can be installed.

Perhaps you should read the OP, because this is explained in #24:

24) I have a newer card that isn't supported by the Apple drivers, how do I install the web drivers that enable it if I can't even boot?

Basically, yes. Definition is MacPro 3.1

Hi MacVidCards!

Any updates on your Quest to find a reliable partner in the EU for us to buy your Flashed NVidia Cards? I really do need a GPU power-upgrade & to free up a PCI slot in my cMP 5.1 (2012).

TIA & Cheers

This would be good to know. The import charge pushes an MVC card out of my reach here in the UK.

Unless any trustworthy US based forum regulars want to help me with a purchase and ship it across as a gift, I'm screwed. (I'd provide all costs up front obviously! :))

To save import charges you have it shipped as a 'used gift from a friend'

Right now my concern is El Capitan drivers before considering my next upgrade. I want to be optimist and think that if drivers are not comin Nvidia would have told us already so that people would not be buying the official Mac edition cards they licensed

Hi, thought it might be beneficial to share experiences slotting a GTX 960 in a Mac Pro 4,1 late '09.

First, as well-documented here, I had to install Yosemite to get any video out on the 960. Vanilla Yosemite provided video out even prior to installing the Nvidia web drivers, but not at my monitors' optimum resolution. I don't recall what the available resolutions were but they were all higher than the 3x 1080p I wanted; the video was scaled and usable if ugly. With the web drivers installed, 1080p was available. I have not tried installing the web drivers on the extant Mavericks boot volume and do not expect that to succeed but intend to try it for the sake of completeness.

Using Bootcamp to install a Win 7 boot volume has also succeeded, although the process was hairy and took several days of troubleshooting to master. I went through two complete clean installs of Windows before I could get the Nvidia installer to successfully implement the current drivers for the 960. I was able to get the correct drivers (.5330) for the 960 both by using Windows Update and by using the Nvidia installer in the end.

However, there are some major issues that remain unresolved.

First, the stock GT 120 (or GT 9500, the OEM EFI card), *must* be removed prior to booting into Windows or Device Manager will become confused and direct video out ONLY the GT 120. Disabling and/or uninstalling either card in Device Manager does not affect this; Device Manager can report either card as active and the other as disabled and the only video out is the 120. On reboot, one of the two cards will be reported as functioning normally while the other is yellow-triangle halted with, I believe, Code 43. It does not matter which card is shown flagged, there will only be video out from the 120. The only way I have noted to get video out of the 960 is to unseat the 120, which makes booting back and forth between Mac and Windows less than convenient.

Second, the Bootcamp / Win 7 audio issue which is customarily resolved by reinstalling the Realtek drivers under Windows does not successfully restore normal audio operability. I have been able to implement an audio solution by plugging in an external USB audio in/out module. This is actually an acceptable long-term solution for me even though it's inelegant.

Hope this helps others running similar configuration experiments.

I can't speak for Win 7 but on 8.1 the Windows issue is easily prevented by not allowing Windows Update to install any Nvidia driver for the GT120. If you allow it to do that it will install an older Nvidia package with 9400/9500 driver that is not compatible with the GTX 980. Your older card will be enabled but the newer card will be disabled. You have to keep an eye always that Windows Update doesn't install it in the future. The GT120 must run only on the generic Microsoft driver.

SoyC, that sounds like a worthwhile experiment. There were definitely some versionitis issues happening with both cards slotted (one would get .533x and the other would get .4xxx, then vice versa, and so forth). WU, interestingly, was actually more reliably delivering .533x than the Nvidia installer. I suppose probably that means that the Nvidia package was trying to limit the driver to a best-fit option for both and fighting with Windows Update.

Running Bootcamp repair off the thumb drive was also restoring the 120 to a reported status as a 9500, presumably also an older driver.

MVC can ship it to my Army mailbox then I can ship it from my German address to the UK. That makes it US to US and EU to EU

Great idea and thank you for the kind offer!

I’ve been doing a lot of forum reading over the weekend though and I’ve reached the conclusion that an unflashed card will be fine for me. It connects at PCIe 2.0 speeds via the web drivers and I can leave my GT120 in slot 3 if I ever need to boot to the recovery partition. I don’t use bootcamp/Windows and as far as I can tell, openCL and Cuda all work fine. So there’s no point in me paying the extra £230 just to see an Apple logo, which is essentially what I’d be paying for.
Unless anyone can point out something I’m missing, I’m going unflashed with a GTX980Ti.

That's what I'd do also.

Please guys share how to do this. I want to sort out this El Capitan situation or at least hear some kind of official word about it

There are no El Capitan drivers from NVIDIA yet, beta or otherwise. Last time, NVIDIA made available drivers for the Yosemite Developer Preview and Public Beta builds, but we haven't seen those appear for El Cap yet.

Edit: And to be clear, I wouldn't call these "officially supported" anyway -- they weren't on the website, and they had a beta version number (e.g. b01 instead of f01).
