Mar 20, 2017 - I went to the Nvidia Website, found my graphics cards, but there is no OSX driver? Will the Nvidia XXXX work in my Mac Pro 3,1 / 4,1 / 5,1? ![]() It is not true that it must have EFI. Many PC 'only' graphics cards work fine in OS X, and they are usually less expensive than the mac version. There's also more choices (gtx 660ti works for example). With a PC video card you will not get BOOTUP screens without EFI, but once you are booted, you are golden. Mountain Lion contains drivers for all KINDS of cards that aren't available in 'mac' versions. I'm using a eVGA GTX 670 4GB Superclock in my 2008 mac pro, and it works great. No boot screen just means you won't get the grey apple and spinning circle while boot happens, it just starts right at the desktop. I boot from a PCI SSD so it's only a few seconds. I kept my old card around in case I ever need the boot screens (like to select boot disk) but I usually use other options for choosing starup disk. I also boot Windows 8 with boot camp and it also works perfectly. Check out the forums and blog at netkas.org for far more info. Mountain Lion made a lot of new things possible, though. Do I get two DVI ports? In the past, not always. 10.8.3 is a 'game changer' Do I have or want to keep a card on hand for when I do need to say use Recovery Mode to do troubleshooting or repairs? Or if you have to download and install 10.8? I have never liked having to find and release the card clasp or lock and swap out a card unless absolutely necessary. IF the Mac Pro would just have 1 x 8-pin in addition to the two 6-pin aux power cables would make it a lot easier. You had to make sure you bought a card with 2 x 6-pin connectors. One person seems to be frying cards, trying to use 6-pin to 8-pin adapters, or you have cables from a 2nd PSU that are messy but provide 450W (2x8 and 2x6). I am not clear if any and all 660ti are going to work or worth it though. And how close a card has to be to reference design. Even support for a 4GB card. Skykick outlook assistant for mac. Or directing CS6 to use the card. Lack of early boot that is provided by EFI may or may not seem like small potatoes. Emulator android for laptop. Sure it can be done. It isn't always necessary to or even desireable to flash a PC card, not nVidia card, and those people - I send them to MacRumors or to 'look around'. I suspect some are better off with a PC and Windows. You can build a i7 3770 that makes a nice graphic workstation or for gaming today. No flashing necesary either. The flashing would ADD efi, but you don't need efi. That said I did need to do some simple patches to have adobe cs6 see the card. Of coure a new machine is a better option, and right now Windows is a better choice for a 'workstation' (and games of course) - but if we're talking about upgrading a 5-year old machine, a little hackery is expected I'd think. Parental control for ios and mac. And it's FUN! I guess I tend to think of mac pro owners as more than casual users. Regardless, even on my mac pro and everything working in os x, I find myself using windows more these days. Just attach the monitors to the older card and os x will use that one. But you want to be careful of power draw. I'm not familiar with that radeon card - if it uses any auxiliary power you may not be able to run both at the same time. You can swap out the old card, install os x and then put the new card back in. I keep my old 8800gt around for that very reason - any time I need the EFI boot screens I change out the cards. It is fine - OS X will recognize the new card once you swap it. Apple Footer • This site contains user submitted content, comments and opinions and is for informational purposes only.
