OS X El Capitan is available as a free update starting Wednesday, September 30 from the Mac App Store. El Capitan supports all Macs introduced in 2009 and later, and some models introduced in 2007 and 2008.
This card works well for me (the Gigabyte manufactured version) but without the EFI, there is no boot screen preceding the Logon screen which is the first thing I see. I am running two Philips 40' monitors at 4K resolution 60Hz using the DisplayPort 1.2 option.
The card runs quiet and cool. Negative side is that when i updated from El Capitan 10.11.4 to 10.11.5 the card stopped working until I reinserted the old card, installed the NVIDIA WebDriver-346.03.10b01.pkg and then replaced the GTX960 and rebooted the machine. I have contacted NVIDIA about this, suggesting that they should allow the installation of drivers for future OS updates and just have those drivers lie dormant until the newer OS kicks in. The other sad fact is that manufacturers of the cards support only Windows OS and aren't interested in providing tech support for Mac users. Hi, I've bought an ASUS GTX 960 and installed the latest Web Drivers for OSX 10.11.3 for my Mac, but when I insert the card and switch the Mac on, nothing shows up, my monitor doesn't pick up anything, it's a black (I don't even think the Mac loads up because when I touch the power button again, without holding down the power button, the Mac just switchs off). I put my old AMD 5770 in and it works as normal.
I've installed CUDA and I've selected NVIDIA Web Driver from the Menubar, but when the ASUS GTX960 is in, the Mac won't load up. Could you help me on this? I have an early 2008 Mac Pro 3.1, CPU-3.2,18g ram Model Name: Mac Pro Model Identifier: MacPro3,1 Processor Name: Quad-Core Intel Xeon Processor Speed: 3.2 GHz Number of Processors: 2 Total Number of Cores: 8 L2 Cache (per Processor): 12 MB Memory: 18 GB Bus Speed: 1.6 GHz Boot ROM Version: MP31.006C.B05 SMC Version (system): 1.25f4 Nivida GEForce 8800 GT Woulld like to upgrade for speed. Please let me know which Graphics card you decide on and any other upgrades I can make to this computer.
I was thinking of 32G of Ram. What should the ram speed be? And adding an SSD boot drive?
I would very much appreciate if you could advise me if this is worth doing, or should I wait for a new MAC PRO. I edit video Thank you so much Gloria Messer 212.355.0815 [email protected]. I just got GTX 770, put it into the computer, launched El Capitan 10.11.4, installed proper driver, rebooted and, the card is not working. The system shows the card but indicates the driver is not there.
I installed then the driver directly from Nvidia. So next I went through the single user and all 'sudo nvram.' Operation, got the card working, reinstalled the driver, went to Terminal to put next 'sudo' command, rebooted, and back to square one, card not working.
My Mac is 3.1. So what do I do now?
As I said in previous reply, the card is not booting. To keep control over the installation process I put the original Mac Pro 3.1 card back together with GTX 770 and of course connected monitors to both of them. Boot starts with GTX, than probably when OS X loads drivers, GTX freezes with boot screen on and stays frozen, while the the other card comes to life showing the normal content. GTX stays frozen all the time, no matter what I do on the computer. If you go to Settings/Monitors, the one connected to GTX is not seen, even after 'Detect Monitors' activation. I repeated the same without the extra card (to check if there is no blocking interaction between the two) and got the same result, a frozen boot screen and no access to the computer.
To make it clear, I had the same on both Mavericks and El Capitan and before and after installing recommended drivers. I also talked to Nvidia who told me that GTX 770 is not supported by their drivers that you recommend on your Web site. I hope there is a solution, because I need that card working and I need it quickly.
