Maybe I'm missing something in the thread, but isn't this expected? From the 1st post of the FAQ:



GTX 760 is Kepler isn't it? If so, it's not supposed to work in Lion.

I was fully aware that the 760 wouldn't be functional in Lion ----but I believed I had read before that the system would still function off the 8800gt just the monitors that were running on the 760 obviously wouldn't work.

My system is crashing upon boot if the 760 is anywhere near the machine.

Clearly the crash had nothing to do with power source as you stated earlier. I was under the impression that you had an MP3,1 because of the 8800GT, but you actually have an older model. I agree with you that the GTX 760 should not interfere with the Lion even without the proper drivers, so the likely cause may be something installed was in conflict with the graphics card. The easiest way to find out is to clean install Lion on a spare USB 16 GB flash drive, and use it as a boot drive. If no KP problem occurs while booting, then you know where the problem lies. On the other hand, if a clean installed Lion still crashes then the GTX 760 card may have some inherent conflict not anticipated when Lion was released.

I can only speculate that Lion Nvidia's drivers are attempting to work with the 8800GT and because the second card is an unsupported Nvidia, it is interfering somehow. You might have better luck if one of the two cards is an AMD.

Solid troubleshooting advice. This is what I'd do.

I plan on doing a fresh lion install as Xcode suggested once I get home and see if that yields any different results---

I have an apple 5770 but due to the fact of this machine having to use bootcamp the mixture of Nvidia and AMD is toxic in windows so I'm sort of stuck

Allright now its starting to get interesting.

I had a GM Lion install disk so installed on new test partition ----machine boots effectively without any panic---the gtx760 and the monitor its connected to is unusable of course. So I reinstalled the GM over my default Lion partition and all was well, yet when I went to software update and updated to 10.7.5 now it panics again. Should I reinstall the GM and stay on 10.7 or should I try to manually download the 10.7.5 update and run it without going through software update?

This may sound a bit crazy, but if it's important to you, you could try different Lion update combo in reverse order with the 10.7 installation. Do a Google search on "Lion 10.7.5 combo update", "10.7.4 combo update", "10.7.3 combo update", etc. I have a feeling it should work at least for 10.7.4, but I may be wrong.

So try the 10.7.4 combo ----by going in reverse will that force a fresh reinstall each time?

I suppose you have to start with a fresh reinstall of 10.7 before applying each combo update. Another way is to start with fresh 10.7 install and then apply 10.7.1 update, 10.7.2 single update, etc until you get stuck. Thus you find out which update would cause the KP.

That's what I thought but was a bit confused---- now that I'm starting to look back at it all, I realize i'm an idiot for not remembering that 10.7.5 had drivers added for further Nvidia support (Fermi etc.) I'll try it again tomorrow but suspect Xcode is right on the mark that 10.7.4 will allow it boot without KP thanks everyone
 
just updated to 10.9.2 - the [beta] nvidia web drivers i had installed, cordially let me know they weren't compatible with the update and used the default OS X drivers. lost an average 3 FPS in benchmarks (some more some less). tried the newest beta drivers mentioned above and they seem to merely be on par (if not slightly slower than) with the OS X 10.9.2 drivers. hears to hoping nvidia releases new drivers soon. i know 3 FPS isn't anything complain-worthy, but would like to have them back.

Had the opportunity to test Xcode's suggestions and confirmed 10.7.4 as far a you can go on early 32EFI Mac Pro's that are using Tiamo's Boot method and are running GTX 6xx/ 7xx cards. If you're running Kepler Cards in your Mac Pro stay away from 10.7.5 for Lion. If you want to be able to boot back in to Lion (last fully supported OS for 1,1 /2,1) to reapply Tiamo's boot file and dont want to physically remove your Kepler card each time (Like what I was going through) 10.7.4 is the latest you can go.

Posting it up so if any future 32bit EFI Mac Pro users face similar issues they can reference

Thanks again Xcode
 
A couple quick questions...

1. Do we want to update the drivers/cuda before applying 10.9.2 or after?

2. Do we have confirmation this plays nice with Tiamo's boot.efi? (just as 10.9.1 didn't touch/did not require reinstall of tiamo's boot.efi)

Thanks,

-Saint

Not sure on the driver's

but as for Tiamo's boot.efi the 10.9.2 update overwrites the boot file so you must reapply Tiamo's after the install
 
I know it's early, but anyone notice any performance bumps? On the PC side, the 334.+ driver deployed Feb 18th said there should be up to 19% performance increases on the 600-700 series, depending on model. I'm wondering if the Mac driver has any noticeable gain. 10.9.2 stock showed really no difference from 10.9.1.
 
Has anyone noticed if their login screen in OSX is completely screwed up after 10.9.2, even after upgrading to the NVIDIA webdrivers (or am I the only one)?

It is as if it is displayed in VGA...

Running GTX680 (flashed) on MP3,1.

Yes. Same issue. You can solve it by going into display preferences. You will find that it is set to the wrong resolution. Just change it and you are back to normal.

Although it took me a couple of reboots and switching back and force between nVidia and Apple drivers before it survived reboots.

Really strange. By the way, the newest nVidia driver disables my secondary display. The second Monitor only works with the Apple driver. GTX680.

10.9.2 certainly ****ed things up.
