I have a Mac Pro 1,1 running OS 10.6.8 (1st-generation 2.66MHz dual Quad core) and my old video card (a nVidia GeForce 7300 GT) failed due to two blown capacitors. I bought a replacement video card (a nVidia Quadro FX 4500) that is a refurbished original MacPro 1,1-compatible card (not a flashed PC card).

1. Intel Graphics Driver

When I installed the new card, it boots and the screen appears properly, but none of the card acceleration works and the card shows in system profiler as only having 9MB of VRAM (when the card has 512MB) and the video is sluggish and not calibrated. If I restart from a hard disk running a non-updated version of 10.6, the card works great, shows up in system profiler correctly, and is fully calibratable. There seems to be a driver problem introduced somewhere between 10.6 and 10.6.8.

Is there any way to make the Quadro card work with 10.6.8? If not, do you know the highest level of system upgrade I can install where it will still work?

Thanks for your help. The problem seems to be fixed. For the benefit of anyone who might experience something similar: I think I messed up the nVidia drivers when I was trying to limp along with the broken 7300GT card. I had removed the nvidia drivers from the system/library/extensions folder to disable the 7300's graphics acceleration so I could keep going at a basic level until I got the 'new' card. I put the drivers back in their proper place when I installed the new card, but I think the system didn't view them as having been properly installed, so they weren't active and the display drivers didn't load properly with the FX4500. I ended up reinstalling the 10.6 system from the install DVD and then updating the software to 10.6.8. This restored the drivers and the display is working properly now.

I hope you see this over a year later. I am indeed having similar driver issues with this card. As a starving artist type, I buy evil bay specials and acquired a MacPro1,1 2.66 'quad' with a working stock GeForce 7300GT however, my G5 that's only a year older experienced graphics related issues which prompted me to at least 'upgrade' to an Intel-based Mac. At least I can update Safari now.

Yay.: So now I have a MacPro1,1 'original' and bought a used (of course) FX 4500 for it. I figured that I'd swap out my cards and keep the GeForce as a spare. That's where my problems started. NVidia does not have drivers available for Mac for the Quadro FX 4500 despite every Apple related community thread pointing to that card as an officially compatible upgrade/special order card which is not only totally confusing but IMHO quite asinine. My question to you is this: will I have to take the arduous path of reinstalling my truckload of music apps, yea, even my entire system if I 'downgrade' back to 10.6.3 from my retail disc? I have the original 10.4.7 disc as well.

(The guy kept everything!) Does the 10.6.3 disc have the proper drivers that may be destroyed when Software Update brings the system up to.6.8? This FX 4500 is recoginzed by System Profiler as a 'G70 Board- q348-0' with nvidia listed as vendor but won't display my system but only lights up the displays with the blue-grey background and no Apple or 'booting' indicator.

That's when the Quadro is the only card in the machine. However, when the oem GeForce card is sitting next to it in slot 2 and both DVI cables are in the Quadro, I get both displays but the 'main' display is on the second and vice versa and the Quadro's fan is slow enough to almost count the fan blades as it turns despite Expansion Slot Utility claiming it's running at full speed and again, unless I have BOTH cards installed, I get nothing but empty blue-grey screens. I did not mess around with any previous drivers and the ones I downed from nVidia are quite wrong as I've discovered. I downed the 'Quadro 4000 for Mac' drivers assuming that it was a 4000.SERIES. similar to the PC counterpart, for example, when you need a printer driver or something.

I'll take this to the community now to see if I have a paperweight or if at least I can flip it. Thanks Peace Blessings. Apple Footer.

Okay so I spend a lot of time of the steam forums. On there, someone posted that if you have the supported cards listed, you can download graphics card drivers straight from nvidia.com for OS X. I was weary at first, but I downloaded them anyway. I have a 2008 iMac with the 8800 GS card (8800M GTS) and before I updated the drivers, I was getting 40 fps on L4D2 with medium settings. Now, I get 40 fps with max settings on L4D2 on OS X.

So that's a pretty big increase. My question is, why haven't these drivers been announced for download if they give a big increase in performance?

I did however, notice some little things. While playing CS:S, there is a little screen tearing, and some other odd little things. Overall though, it gave me a huge performance increase.

Click to expand.It's gone now, my ping was spiking, that was the problem. So far, the drivers have significantly increased performance, nothing weird has happened.

And I know VSYNC gets rid of the screen tearing, I had it on while it was screen tearing, which led me to realize that it was from the ping spiking up and down. I mean, the drivers clearly state which graphics card is supported, and there from nvidia.com. It's not like it's an unreliable source lol. If anything happens, just roll back to your original drivers.

I'm sure theres a way. It's gone now, my ping was spiking, that was the problem. So far, the drivers have significantly increased performance, nothing weird has happened.

4) right-click the 'NVIDIA Retail Mac Driver.mpkg' and choose 'Show Package Contents'. Open Contents/Package and you will see three pkg files. Install the three pkg files separately (the order doesn't matter). After successfully installed the three pkg files, reboot your mac. 5) everything should be fine after you reboot.

There is a way to back up your old ones, but I didnt. HUGE SUCCESS so I installed them and everything works good. A week ago when i played the cider port of Modern Warfare 2 (it is the second Cider wrapper, the update) i had to turn down the graphics to low and to 1280x800 resolution in order to get smooth gameplay.

Its always been like that, which is why i literally never played it. This is on my 2010 15' i7 with GT 330M. Now, after upgrading the drivers, i turned the graphics to extra, and its totally smooth aswell i kept the same res. Then i changed res to 1680x1050 and the graphics to high, still smooth the difference drivers can make. Click to expand.He did say that, although this thread was made prior to Lion. I installed this on my iMac 09 with the gt 130 (not supported) with success. I recently installed a SSD and a fresh copy of snow leopard and used smalluxGPU to stress my GPU (new thermal paste installed) and noticed very poor performance.

If you know the scores on the benchmark GPU with OpenCL pixel filtering, it went from 60/27/9 (millions of samples/s) to 169/61/40. I couldn't figure out any other reasoning for this, until I stumbled across this thread. This is amazing!! 1) make sure you are running Mac OS X 10.6.5 or later. 2) download the driver from nvidia 3) double-click the downloaded dmg file. 4) right-click the 'NVIDIA Retail Mac Driver.mpkg' and choose 'Show Package Contents'.

GeForce 9400M So I will say that my interest in updating drivers is different from most in the thread who seem to be needing better gaming performance. I recently purchased a Dell U2913WM ultra-wide monitor which looks fantastic except that it lags when playing back HD videos and downloading files (?).

I installed the cudadriver and the package contents from the NVIDIA Quadro Retail Mac Driver 256.02.25f01 though I noticed 5 separate installers, the three driver installers and two packages called pre-install and post-install which I ran in the intended order. Fortunately I didn't have any black screens, I am running Snow Leopard 10.6.8 but I haven't noticed any performance enhancement. Ram memory test for mac. I wish it was like on a PC where there is a more advanced application for monitoring graphics or even knowing what version of drivers you have installed, on get info from my MBP I have Revision ID: 0x00b1 Does anyone have any ideas of what I might try next? I was thinking about upgrading to Mavericks 10.9 seeing as how some had said there were performance enhancements on a system level but naturally I am weary here for other reasons.
