Hi folks, Forgive me, but I've had a few frustrating days. Installing both Yosemite and El Capitan was trivially easy following the instructions on the first page of the thread (install via target disk mode from eligible machine, swap in Pikes boot.efi, repair permissions, done) That was awesome. I then hastily and foolishly pulled the trigger on this card from Amazon after reading multiple posts on multiple forums that essentially said 'nVidia cards work oob and work better with the latest web drivers'. The GTX 750 was noted as a card the required the web drivers and wouldn't display a boot screen on page 1 of the MacPro 1,1/Yosemite thread. A new 2GB, DDR5 card for $150 was impossible to resist and I accepted those caveats.

I take FULL RESPONSIBILITY for not reading ALL the threads. I realize that most, if not all the people here are trying to help one another. I'm not angry or blaming anyone other than myself. The linked card above did not work either oob or with the correct web drivers for either Yosemite or El Capitan.

It's going back to Amazon. I'd really appreciate if someone could steer me to a currently available card that they are currently using on a 'stock' MacPro 1,1 that works with Yosemite and El Capitan. Here's what looks to me to be an option: but I hesitate bc it's PCI 3.0 and much of the performance will be lost in a PCI 1.0 box. So, please, if you could list your card here, I'd appreciate it. I'd rather not have to wait to get a card flashed, so please share your experience and PLEASE, if you don't know that given card works, don't speculate unless you are truly an expert. I just switched to El Capitan using my funky-but-functional Radeon X1900 and grabbed this screenshot: Is there any way for that to show without the drivers actually loading? I've zapped PRAM several times and toggled nvram bootargs from =nv_disable=1 to nvda_drv=1 a few times.

Jul 19, 2017 - I have a Mac Pro 1,1 up and running on OS X El Capitan 10.11.6. Video card is a ATI Radeon HD5770. I've just installed PT 12.8 and all new.

Just ran nvram bootargs and got 'nvda_drv=1', so I think everything is in place. I'm looking at flashing instructions now, but it would be my first time and those who've done it a lot recommend learning on easier and more recoverable cards. Between this and installing Linux, I've gotten a HUGE education thanks to helpful people like you. New autoplay media studio 751006 full version 2016 free and torrent. For less that $100?

You did quite well for yourself. I just ordered a on Amazon for $140. I spent the entire day reading and debating between the 7950, the 7970 or GT 600 series nVidia card. I went with the Gigabyte card bc I can have it on Saturday and Gigabyte is kind enough to still provide the ROMs, although there are 4 listed for that card, and I'm not certain how to tell which is correct.

I've got til Saturday to figure that out. I'm all over the Netkas forums and the Radeon 7xxx thread.

Did you run Netkas' script from the OP? Or what did you do?

I don't have a PC or a copy of Windows to install, but I think I should be able to add the Mac EFI to the ROM I download from Gigabyte and then do everything from the terminal on the MacPro. I'm still reading and trying to sort wheat from chaff. If you could point me to a specific post # in the 30 pages, that would be great. I'm not sure if Netkas' script in the OP has been updated/fixed or whether it needed to be. So many people give authoritative advice that is just so wrong. 'any GeForce card will work,' WRONG!
