Preparing for El Capitan 10.11 !
I know that many of you are excited about El Cap coming in 2 days. I need to remind you that all newer Nvidia cards require delicate planning whenever there is an OS update.
The good news is that our EFI cards make this easier then for the poor souls with unflashed cards. They end up staring at a black screen as their Mac endlessly reboots.
So, if you have one of the following cards you need to think before hitting that "update" button:
GTX Titan Black
All of those cards have been left out of OS X since 10.8.5. Will Apple ever include drivers for them? Hard to say, but until the iPad Pro comes with a 980, maybe not.
So, again, please come here or read at Macrumours Mac Pro section or Netkas.org to see what the news is on the 30th. We are on the West Coast so lunchtime for you may be breakfast for us, we may not have the first posts.
Currently the GM build has numbers that match the linked driver from our driver page. If Apple changes the build number for Final Release, expect Nvidia to have an update. Unfortunately, if Apple springs the change on Nvidia at the last moment, it may take a day or two to be issued. If there is a work around, we will post it here. It is also possible that Apple will keep the GM build version and all will be well. The current Nvidia driver has a "b" in the version number, that means "Beta". Expect a release with an "F" in the Final one.
Again, please think before you hit "update", if there isn't an Nvidia driver yet you will be really mad at yourself.
UPDATE: Not only was the Beta driver compatible with 15A284, but Nvidia has already issued a Final driver for 10.11 Build 15A284. Please see the driver download page.
For those running Yosemite on an EFI card from us that requires Web Drivers, you will need to do the nv_disable step to install El Capitan, then turn the drivers back on via terminal. See the instructions here:
Please note that the nv_disable terminal command does not have to be done from single user mode, it can be done whilst running a previous version of OS X before you run the installer.

The September 22 update to 10.11.1 after the GM release broke the driver as it was a 15B not 15A ....

Today's release of OS X El Capitan (15A284) worked fine for me with NVIDIA Web Driver 346.03.01b07. To get everything going, I went to the App Store and downloaded El Capitan. After the installer ran, when it finally rebooted to begin the install, I held down Command-S to go into single user mode so that I could disable nvidia drivers:

Excellent ! I can report that using a 980Ti and trying to run the Final installer WITHOUT disabling Nvidia drivers doesn't work. I booted into 10.10 and used terminal there to set the value in NVRAM. (same effect as doing in single user mode) Very next time I booted again the installer continued. The Web Driver only checks for "15A" for build so will at least try to work for any and all El Cap 10.11 versions.

After the first reboot / CMD S startup, I had no vision, so I typed the arguments in blindly, is that what's supposed to happen? Then indeed it restarted again and went on installing. :)

No, you should have some sort of display. Sounds like you made it work anyway, so good job!

Bingo! About an hour ago the old nvidia control software informed me that a new driver is published. Installed the final driver 346.03.02f01, reboot, shut down, installed the 980 ti again, and ... yes you guessed correctly ... it is working again with el capitan.

Just an FYI for anyone reading out there. I tried Robert's method above. Command + S and disabled the nvidia drivers (was getting caught in a boot loop prior to doing that...). Continued install into El Capitan. Installed 346.03.01b07 and rebooted. Definitely working, but not working well, so then I installed the driver "update" when prompted 346.03.02f01. Both drivers do work (i.e. let me boot into El Capitan), but yield marginal results (tearing, lag and other issues).

I'm getting the same thing, boots up into El cap fine but seeing some intense lag, mouse, scrolling, mission control etc. I have a Titan in my 3.33 Hex Mac Pro as well. Not sure what's going on either.

So El Capitan is in general release ....
10/1/2015 04:02:30 pm
Robert, you are not correct about boot-args, they definitely stay or there would be no purpose for Nvidia to release the driver at all. I have rebooted El Capitan 20 or 30 times on a variety of Mac Pros, no trouble having drivers quit. I am going to guess that you have buggered up your install somehow by going to 10.11.01 and then back to 10.11.

That is good news ... so much speculation at this point.

GTX 760 works fine with both drivers

I am at the endless loop stage. Cmd-s did not boot to the black screen with text as described. I am a bit over my head with this. I had no idea the problems I was getting into. The old card is dead so I can't back up unless I buy a new old card?
