Any GeForce wil work and of course the Radeon 7950.

HAL - PLEASE don't make blanket statements like "any Geforce will work". There are hundreds of variations of cards with the "GeForce" moniker and I absolutely guarantee that your statement is far from accurate and likely to frustrate and waste someone's time. In my case, I've spent three super frustrating days on this and other forums because I have not been able to get my EVGA GeForce GTX 750 Ti SC to work at all in my MacPro 1,1.

I bought it from Amazon 3 days ago bc it has great specs for <$150 and I read here and in multiple other places that Yosemite and El Capitan support any nVidia card OOB.

This is the exact card on Amazon.

Not only does it not work OOB, it doesn't work with the latest web drivers in Yosemite or El Capitan. I've tried literally everything. No go.

I can't speak for sure about other variants of the GTX 750. Several people report it works for them but it gets very hard to be sure that someone is talking about a completely stock MacPro 1,1 or a hackintosh or something in-between.

I do absolutely guarantee that the card linked above will not work in a stock MacPro 1,1. I'll *speculate* that none of the "maxwell" generation will work because the PCI in the cMP is 1.0. Just my theory and I'd be happy to be corrected and educated by someone who is more knowledgeable than I. (MacVidCards?)

People are coming here looking for answers. I understand and appreciate that you're trying to help, but unless you have a MacPro 1,1 and you've tested every single GeForce card and they all work, don't say they do. Please and thank you, sir.

EDIT: I'm not trying to offend HAL or anyone else. I'm just sayin'. I read a similar blanket statement three days ago and pulled the trigger on the linked card. It's going back and I'm *still* not sure enough to pull the trigger on another card. It seems crazy to spend ~$150 or more on a used card on eBay or some other place where returns will be questionable when there are so many choices of brand-new cards.

I'm practically begging someone who owns a stock MacPro 1,1 and has upgraded to El Capitan in the last few days to tell me what currently available mid-range card ($150) will work. So much that I'm going to start a new thread.

Thx for making this possible. I successfully upgraded from Yosemite 10.10.5 to El Capitan today on my mac pro 2,1 with radeon 6870 1gb.

I actually wanted to wait for 10.11.1. But I decided to do it today. And it works with no issues so far.

No, not the flashed card from MacVidCards, the card that I linked and bought from Amazon three days ago.

If someone reads your post, near the end of the thread and just a few days after the release of El Capitain, they, like me, could go and buy "any GeForce card" (your exact words) and be frustrated and disappointed. I thought I was being courteous and reasonable in asking you not to make blanket statements. The fact that you found "my" card in a flashed version is totally irrelevant. Flashing is neither trivial, nor cheap (+60% in my case), nor fast (5 or more days) for someone who comes here looking for advice on a video card for a MacPro 1,1 to run El Capitan.

If you care to edit your response and say something along the lines of "many GeForce cards, some requiring flashing" then I'll stop insisting that you are wrong. As it stands now you are not only wrong, but VERY wrong is someone takes your response totally literally and goes and wastes his time and money. I'm not going to waste any more time with this, but I guarantee that not every single card that says "GeForce" dating back to whenever nVidia started using the name and thru the latest maxwell generation cards, will work. My card says "GeForce". It's brand-new, not defective or broken. It does not work in a MacPro 1,1. Case closed regardless of the likely hundreds of other example.

Wow. Man you are frustrated. I've flashed dozens of cards. I never wrote all GeForce cards will work OOB. You could have been more friendly about this. Your behaviour towards me is not correct I'm sorry to say. I changed my mind, as you can read in posting #728 about posting on the subject of videocards in this thread. It doesn't belong here. Please go to the Netkas forum about this subject. But I believe you already posted over there. I hope you will learn how to flash your card.

FWIW, I just tried an EVGA 750 in Mac Pro 1,1. Was completely invisible. Had an EFI64 UGA rom, will try a 750Ti with a PC UEFI. Not sure why it is invisible. I tried the Titan-X and it was fine.

I started with "Please" and ended with "please and thank you, sir." I don't know how much more friendly and respectful I could have been.

Yes, I am frustrated. Mostly with myself, I suppose, because I pulled the trigger on a card based on what people like you have said. I'd have been better off if I'd spent another day reading every post vs. wasting two full days only to send the card back to Amazon. Now I have a $150 credit and I don't know what card to buy.

So, I came to this site and found this thread:

2006/2007 Mac Pro (1,1/2,1) and OS X El Capitan

And what I have taken issue with is your statement that "all GeForce cards will work" - no caveats, no asterisk, no "in my experience", no qualifiers whatsoever. That was and still is misleading and unhelpful. EDIT: "almost" doesn't make your statement any more helpful. There are thousands of cards called "GeForce" from dozens of suppliers with variations from slight to very significant.

Video cards are not only relevant, they are critical as far as running any OS past Lion on the MacPros that are the subject of the thread, so this is absolutely the appropriate place to talk about them.

All I need is a video card that works
. Maybe I'm wrong to think I should be able to do it for $150.

Both Yosemite and El Capitan are installed and running. So, again, your response is frustrating and totally unhelpful. Adding to it that you've flashed a dozen cards and you hope I'll learn is also totally irrelevant...

Before we go any further: Do you have a MacPro 1,1/2,1? With a 32bit EFI? If so, I beg you to tell me which GeForce card you are running. How did you flash it? MacVidCards says here that, "Last EFI32 flashable Nvidia card is 8800GT 1GB." That's his business and he's all over the forums, so I'm inclined to believe him.

As far as Netkas is concerned, yes I've been there as well. There is one post among that page full that talks about a GTX 750 running on a MacPro 1,1. I've yet to discover the exact model/version/vendor of the card, but I won't be doing any flashing until I've checked with several reliable sources.

If I have to go that far, I guess that's how far I have to go. It would be awesome if someone out there said, "I bought this card - with a link to the exact card - and it works in my MacPro 1,1 running El Capitan," (or Yosemite).

It is totally useless and mostly wrong for someone to say "almost any GeForce will work" to run El Capitan on a MacPro 1,1/2,1 with a 32b efi. Have a nice day. :)

LOL. Are you asking me if it will work or telling me that it does?

It's in my budget. I'd LOVE someone to tell me it works in a MacPro 1,1... Anyone?

Hey, try switching number of PCIE lanes to 4 or 1.

Just got my 750 to show up by putting in slot 2 and trimming it to 1 lane.

Next will try slot 3 or 4 and give it 4 lanes.

I'll bet you get it working if you play around a bit.

Alright, a little bit of pain here.

I made the El Cap attempt and ended up with KP at the start-up - black screen, Apple logo and text in the upper left describing KP - frozen. I checked and re-swaped boot files in all three locations, numerous times - no love! I've since done a TM restore and I'm back to my original Yosemite 10.10.5 - square one. My Mac Pro 1,1 to 2,1, 2 x 2.66 GHz Quad-Core Intel Xeon with a ATI Radeon HD 5770 1024 MB runs like a champ! A H M A Z I N G!

Questions:

1) Before I started the El Cap upgrade, I noticed I had a boot.efi.Tiamo file in i368 (see attached). This made me suspicious. Now, I cannot remember if I ever ran the YosePikeFix script, or if I did some other solution that allowed me to update all the way to 10.10.5. I never had to replace any efi files after any upgrades - they all installed without incidence. Is Tiamo causing headaches? Although, it disappears (overwritten?) after El Cap installer is run.

2) Should I go ahead and run YosePikeFix now for good measure before I attempt another El Cap install?? Is there something with the YosePikeFix besides the boot files that will allow El Cap to install properly??

3) Do I risk mucking anything up if I do??

4) Can anyone please point me in the direction of the definitive YosePikeFix procedure, if this is something I should do??

5) Is there any way to tell if you've run the YosePikeFix???

Thanks very much for any anticipated observations!!

  • I bought the EXACT card and like you I have had no luck getting it to work i guess i have to return it or find some way to get it to work. ANYONE who has a solution please reply I am currently using a gt610 that really doesn't fit my needs, I already have El Capitan installed and running on my 1,1

Hi Sweets - Did you use the latest macosxbootloader file for El Capitan? On Github here

I installed El Capitan from an eligible iMac, replaced the boot.efi files and - aside from my video issues - El Cap is working like a charm.

LMK how it goes ;-)

Hey Krech - I'm sending mine back. I've gotten it to output video putting it in alternate slots, but it's literally cutting the performance in half to run it with only 8 lanes. So strange that it's recognized and functional in the other slots and not the main. All I can guess is it's a power/PCI 1.0 issue...

Let's stay in touch and help each other out if we find another card of a solution. I'm crawling every forum and poking anyone I can...

Cheers

EDIT:
Is your GT610 the 1GB variety? I just searched Amazon and found this variation
for $50?!?
Is that too good to be true? It does say PCI 2.0... but if it works for $50, I'll jump on it.
I play games on PSX...

I'll see your slot 2 and raise you a slot 1:

Screen Shot 2015-10-07 at 10.23.54 PM.png

Slot 4 isn't an option as the card won't fit with the drive in there and 4 internal drives is one of the great things about the cMP. This is definitely looking like a power/PCI 1.0 issue. The Gigabyte version of this card reportedly has an additional power requirement, but that thread (on Netkas) starts with the OP confirming the card does not work on his 1,1.

Imma see what happens when I pull the Radeon out and it's just the GTX750...

Thanks to all the gurus here I installed El Cap on my 2001 1,1 by using a friendly 2010 iMac to install it on a USB HD, then replaced the EFi files and copied it back to my Mac pro before booting. Works a charm! Thanks a million guys.

3 questions though if I may?

It wakes from sleep fine, but if you shut it down and restart it takes ages to restart, doing a double chime in the process, and when it finally does start it reports that the computer was restarted due to a problem. I can live with this but is there something I can do to prevent this?

I have a pair of quad core 2.66 cpu's that I am thinking of installing. I understand that they should work fine with the native (1,1) firmware, but the system info will not report the cpu identity properly unless I flash the firmware to 2,1 (using netkas.org's patch.) Will this muck up the 64 bit EFi patch however and stop my machine booting? Again I can live with the system info looking wrong if there is any risk from flashing the firmware as I understand that the cpu's work fine with the 1,1 firmware?

What is likely to happen when El Cap updates come through. Will they overwrite the EFi? As Pike's Yosefix type solution doesn't work with El Cap due to SIP that would be a pain.

Thanks again

Robin.

ok let's see... :)

Questions:

1) Before I started the El Cap upgrade, I noticed I had a boot.efi.Tiamo file in i368 (see attached). This made me suspicious. Now, I cannot remember if I ever ran the YosePikeFix script, or if I did some other solution that allowed me to update all the way to 10.10.5. I never had to replace any efi files after any upgrades - they all installed without incidence. Is Tiamo causing headaches? Although, it disappears (overwritten?) after El Cap installer is run.

I think boot.efi.Tiamo doesn't do any harm, but since this file belongs to Mavericks, I'd remove it - it's useless anyway.

2) Should I go ahead and run YosePikeFix now for good measure before I attempt another El Cap install?? Is there something with the YosePikeFix besides the boot files that will allow El Cap to install properly??

PikeYoseFix is only for Yosemite. No point in installing it for El Capitan. Since you are already running 10.10.5 which is maybe the last Yosemite update, it might not be necessary. If you're still unsuccessful with 10.11 and a 10.10.6 comes out, then run the script... But you DON'T need it for 10.11.

3) Do I risk mucking anything up if I do??

I wouldn't do it - PikeYoseFix makes sure one specific version of the boot.efi is in place, and that's not the El Capitan one. So I would avoid it.

4) Can anyone please point me in the direction of the definitive YosePikeFix procedure, if this is something I should do??

No. Just don't do it ;)

5) Is there any way to tell if you've run the YosePikeFix???

If you had used yosepikefix . It would have shown in I386 . I don't think it made a difference . Since it gets over written by el Cap install. After full install did you boot it up directly from the Mac Pro ?

any video cards suggestion for my awesome mac pro 1.1?
The Radeon R9 280X is a pretty popular choice (I have two of them myself and they work well). Check the thread about Yosemite for 2006 Mac Pros started by Mr. Zarniwoop - there's some discussion of video cards there (start with the summary in the original thread).
