I don't know if this has been asked already, but I cannot seem to get sound out of my GeForce GTX 760 when running under OSX. My monitor is a cinema display, and the audio works just fine when plugged into my Macbook. Only when my MacPro is hooked up do I not hear any sound from it. Also, I do not have this problem in Windows mode, only MacOSX. Is audio support not concluded in the NV driver or is audio not supported for non-EFI compatible GPUs? Thanks.
Which Cinema Display are you talking about? On mine (24-inch LED Cinema Display), the audio is sent via USB.
 
Hey, Thanks Asgorath! Say, what's the benefit of using this over the NVidia supplied updater?

The most obvious usage is the fact that this app will automatically find beta drivers for Developer Preview OSes etc. It's also useful if you don't already have the driver installed and want to find one for the first time. Otherwise, yes, the built-in updater should work fine. Nice to have an alternative just in case though.

Ah, very good! Thanks for the clarification.
 
Awesome thread! I've a 3,1 Mac Pro and looking at adding this DirectCU II GTX 750 Ti
Does it support a 30" ACD? The ACD requires a dual link DVI port, and from what I can tell the GTX 750 Ti does have one.

EDIT: I also have a second question:

I read the following on the first post:

17) Are the PC cards forced to only use PCIe 1.0?

The PC cards used to be forced to only use PCIe 1.0 (2.5GT/s), but the most recent drivers from NVIDIA for Mountain Lion (304.00.00f20 for 10.8.1, 304.00.05f02 for 10.8.2) appears to remove this restriction under Mac OS X. The PC cards will still run at PCIe 1.0 speeds under Boot Camp, however. Note that this only affects the MacPro4,1 and MacPro5,1 models, earlier systems will still only run at PCIe 1.0 speeds.

My guess is that the PCIe bus speed is negotiated by the EFI, and defaults to PCIe 1.0 when there is no EFI on the card. The latest NVIDIA driver for OS X appears to work around this somehow, but the same fix hasn't been (and probably won't be) applied to the Windows drivers.


I wanted to ask if this is still the case? Is there much of a performance loss running at x1 in Windows compared to x2? I don't play games in OS X at all -- only in Windows 7.

Appreciate any info about this!

...and does this mean that 3,1 is restricted to pcie1.0 in any case?
So flashing my 670 would speed it up, even when I don't need it for boot screen since I have also 5770...

From what I've been reading the performance loss isn't too bad: link

Very interesting. I should finally take the dive and try a game or two in Windows. I'd convinced myself it would be a massive hit, where thinking about it, 16x at 250mb/s is still 4GB a second... I can load my entire vram/s. Shouldn't hold me back too much.
 
Hey, we have had a few people who clicked on the 10.11.1 update before realizing that there isn't a web driver out yet.

No big deal if you have a GTX680 or another OS X standard supported card. For the "Web Driver Only" cards, this is a problem. Non-flashed ones will likely just give you a cheerful black screen. The EFI cards got lucky again, the EFI allows you to get to desktop and wonder why it is so slow and clunky.

Anyhow, I'm sure that Nvidia will have a 10.11.1 Web Driver within 48 hours, probably 24. But for those who already updated and need a fix, have a look at our blog, just put up instructions. This is ONLY for people who already ran the update, I really don't advise doing it unless you already made the "update" error.
 
Thanks for the information. I will save it just in case. Thankfully Apple has not forced the "Install OS X Updates" in system prefs as the default yet.

10.11.1 driver

http://us.download.nvidia.com/Mac/Quadro_Certified/346.03.03f01/WebDriver-346.03.03f01.pkg

Still has the random 'Can't open Nvidia Driver Manager' warning when the OS boots but it works nevertheless.


Thanks!

What's the best way to update to it (from OS X 10.11) if I have a non-EFI GTX 970? I remember you posted something about not having to change the boot-args and without having to use an EFI card to do it, but can't find that post. :)

Instructions are at the start of the thread. I just use a standard Apple card with all OS updates after the web driver comes out.

Okay, thanks. So one has to use another graphics card. I was hoping there was a way to skip that.

What I did was to simply take out my SSD and connect it to a MacBook Pro and start up from the SSD on that, install the 10.11.1 update and the new web drivers from Nvidia. Then put the SSD back in my Mac Pro. I still think this is quicker than putting in my old EFI graphics card, even if iCloud credentials has to be re-entered. :)

That's a good way too if you have a newer Mac. Especially if you keep a test bed/back up on an external drive.

Running Yosemite 10.10.5 same issue with update.
I always perform a CCC backup prior to any update. That being said I installed the update as well and the computer reverted back to the Apple driver. I downloaded the 10.10.5 (14F Beta} 346.02.03b01 and installed this driver and the computer is working fine. I can still clone back to my previous install but I do not notice a difference in performance or stability, so I will probably just use this driver till the newer web drivers comes out
 
Anyone have a direct link to the CUDA 7.5.21 update installer?

One machine has not been able to successfully use "UPDATE" from the system preferences for CUDA installs. NVIDIA Web Driver updates fine, however.

Sorry, no luck here for the CUDA driver 7.5.21. I updated it with the preference pane:

CUDA_7.5.21_ScreenCap%202015-10-23%20at%2015.24.53.jpg


BUT, after updating the security update for OS X 10.10.5, I lost my NVidia Webdrivers.... pfffffffffff

Cheers

EDIT: webdriver updated to 346.02.03f02 -> see post https://forums.macrumors.com/threads/broken-nvidia-web-drivers.1931085/#post-22131421

All working fine again, thanks NVidia! :cool:
