Yes it does, I was just getting ready to post this. You beat me to the punch:p

Smoothest El Cap update yet. No forced reboots, long install times or any shenanigans. Install, reboot, install Nvidia driver, reboot, done in a few minutes.

A quick recap of my upgrade:


thanks for the link

Downloading the latest Nvidia driver, it required 10.11.4 to install.
Updating to 10.11.4 the 970 no longer functions.
Rather than swapping around PCIe Devices, a USB 3.0 display was an easy way out install Nvidia's latest drivers.
Although logging in appeared to hang, replugging the usb display cleared the issue.
After the install of the Nvidia drivers and a reboot, all is happy again with a non-flashed gtx 970.

fwiw... i have a spare 5770 gathering just in case..

Do you mean to say that you did not set boot-args="nv_disable=1", and your Mac still booted? That's huge news, isn't it?

Also, at what point does your USB display become active? At the login screen or desktop?
 
Hi guys,

Just to let you know, after the restart of El capitan update, I had gray screen for 10 to 15 min, and everything came back normally, Apple logo and so on so forth. Once finished to reboot, I installed the nVidia web driver and reboot without any issues.

Cheers
Regis

I found the easiest way is just to remote desktop into the Mac and install the drivers. I actually did the whole upgrade process from work. (VNC, Update OS X, VNC, Install Drivers, Done)

You don't need nv_disable anymore since 10.11. If webdriver is installed and version of osx mixmatch version of webdriver, you'll get same behaviour as with nv_disable.

Flashed cards allows to update without nv_disable and retain the display output all the way.

AFAIK, I did not set boot-args="nv_disable=1" on this cMP. I've only installed the web driver using the usual point and click approach. It was on my list of things to do since I found a deal on a 970GTX a couple weeks ago for $250. Without a flashed card, the update visually progressed normally, just leaving the mac in a state needing the install of the new driver. Showing the login screen on the USB Display.

The USB DisplayLink Drivers load in the boot process and becomes active before the login screen appears. Cheap USB 3.0/2.0 display adapters can be picked up for $40 or less, USB Display's start around $80. Either make a great fall back in case of a Nvidia driver snafu.

Personally, I'm using a Lenovo Touch Screen / Pen device that comes in handy for iOS/Touchscreen development.

I missed that news. That's great.
 
With an EFI card it's been great avoiding the boot loop and not having to do an nv_disable stuff either. It basically just works. Do the point update to OS X, reboot. Update Nvidia drivers, reboot. No drama.

But I guess I got coddled because I ran into a problem later, when upgrading from Yosemite to El Cap. After running the El Cap installer app and rebooting, the Maxwell boot loop occurs. I think, no problem, I'll boot into single user mode and add the boot arg. Except the installer boot process don't seem to have a single user mode--holding S did nothing.

Testing my bootable USB installers for ML, Mavericks, and Yosemite all showed the same thing. I can't enter single user mode to change the boot args, and so the boot loop occurs on all of them. Same thing with the Yosemite recovery partition.

So, moral of the story--if you're going to do a full OS upgrade, make sure the nv_disable boot arg is set ahead of time before you run the installer.

Also, a question. If you didn't do that ahead of time, how would you enter single user mode or otherwise set the NVRAM boot args for a booting installer?

Luckily I have a Mac Mini and OS X doesn't care which hardware it is installed on. So I moved the drive to the Mini, finished installation, and moved it back to the Pro. But I'm not sure what someone without a second Mac would do, once they were in this situation.
 
Well, I was hoping the new nVidia Web Driver would fix a months-old problem I've been having on my Mac Pro 3,1 running the latest Mac OS: When the nVidia Web Driver is enabled, the boot progress bar goes about half way then freezes. The white screen with the single Apple logo and progress bar remains frozen for all time...

The computer is configured as follows:

1. nVidia GTX970 EFI BIOS flashed by MacVidCards.
2. Sonnet Tempo SSD Pro Plus PCIe card with 2 on-board SSDs serving as the boot disk.
3. Inatek USB 3.0 PCIe card.
4. Original WiFi/Bluetooth daughtercard replaced with one that supports 802.11ac and Bluetooth 4.0.

When using the standard Apple Graphics Driver, there are absolutely no problems. However, when the nVidia driver is enabled, the boot process freezes at the half-way point (the point at which the graphics driver loads).

Anyone experiencing the same issue or have any suggestions on how to troubleshoot?
 
I was given an Asus GTX 670 2G (2 x 6 pin) that works without problems in a Windows PC but installing it with the correct two power lines from my Mac 3,1 motherboard running 10.9.5, or 10.11.4 or 10.11.5b1 produces no video at all at any of the video out connectors. The MacPro RAM posts, and the card fans are running but no video at all even after waiting 15 minutes for the log-in screen, which remains black. I thought 10.9.5 and 10.11.4 supported this card OoTB but am not surprised that 10.11.5 does not because there are reported driver problems even with the GTX 680 Mac edition. Is there anything else to try, like installing the nVidia web drivers for 10.9 and 10.11.4?
Suggestions?
 
This morning tried resetting PRAM and running card with external power—nada.
On point of giving up, selling card and buying a Mac edition of something.
 
I dled them and installed using an nVidia 8800 as the video card (slot 4). To see what was happening, I installed both the 8800 and the 670 (slot 2) with the 8800 powered off the MacPro motherboard and the 670 powered off an external PSU with video connected to the 8800. In this configuration, the gray progress bar got half way across, stopped, the screen went black and the Mac rebooted. This reboot happened a second time too and a third and so on.
Next, I booted in Safe mode and the gray progress bar went past the previous stop place, paused at 2/3rds and then finished up and I got to the log-in screen.
Here is where it gets weird—remember the display is connected to the 8800. I switched the video to all the 670 outputs and nothing. About this Mac—Displays shows the correct presence of the 670 with 2 MB as driving the display BUT it is not. See upload pic 1. Next, More information shows the presence of the 8800 and the 670 correctly (pics 2 and 3). Kextstat shows the loaded nvidia drivers (pic 4). So the system knows the 670 is there but there is no video out.
Last, I tried to launch the nVidia Sys Preference but it won't load because the Mac is booted in safe mode (pic 5).
To me, this suggests there is a drivers problem and not a video hardware problem.
I don't know if this helps anyone.....

Wasted another 2 hours Sunday afternoon on the sudo nvram boot-args="nv_disable=1" and sudo nvram boot-args="nvda_drv=1" and sudo nvram -d boot-args methods from MacVid cards blog but nothing will make this damned Asus GTX 670 2G display anything from any port.
Selling it to a Windows fan and sticking with the old 8800 for time being. Learned a lot but (Grrrrr) this efi Apple video card rom stuff is frustrating. Why is Apple such pricks over this? The "new" 2014 with its limited in-case storage is a PITA when one needs 20 TB of fast external storage, so these old suitcase MacPros still have great value if the GPU can be upgraded for a reasonable price.
 
Another hour spent on going right back to ML 10.8.5 which should just work with a Kepler card and does not, so there is something about this Asus GTX 670 that prevents it working—could it be missing device ID in info-plist?

The Nvidia drivers built-in to OS X should work fine with Kepler cards. You should not need to make any changes nvram. All the versions of OS X that you tried should just work.

The Nvidia web drivers should also work but are NOT needed for Kepler cards. They are entirely optional.
 
I know it SHOULD work but it does not. There is no output from any of the 4 video outputs on the card backplane—see my posts.
The card works fine in Windows 7. No idea what the problem is but I have exhausted all the test avenues I can think of.
 
Have you tried a clean install of OS X? Have you tried without the 8800 GT installed?

I think something is preventing the drivers from loading on your system.
 
If I remember correctly, MVC mentioned that (some) GTX 670 causes trouble, that's why he's not offering them in his shop, avoiding ASUS cards anyway.
