And finally, for Mac OS 9 veterans, thanks to Endymion, Voodoo 4 4500 flash kit & voodoo 4/5 latest drivers for Mac OS 9 (Mac ROM can be obtained directly from within the 3dfx control panel, using ResEdit): Download (ZIP)
Unflashed grafic cards for windows systems should work, but they dont show the booting screens, until osx has fully loaded. So in case of booting problems you will not see any error screens, and the osx boot volume selection screen (where you choose between osx and boot camp) cannot be displayed.
The GTX-680 is actually the last Nvidia model that is potentially possible to flash yourself to have Mac firmware. This is done using tools in Windows, I did this myself with a GTX-680 using Windows via Boot Camp on the Mac Pro itself. Once this is done it will then show the pre-boot options like a real Mac card.

You will need to contact your graphics card manufacturer for the latest custom UEFI / video BIOS for your graphics card. Flashing a graphics card with an incompatible or untested version can permanently damage your graphics card. Most graphics card related fixes are provided through display driver updates. If you are experiencing issues with your graphics card, then before flashing a new video BIOS update, we recommend downloading and installing the latest drivers for your card.
Need instructions how to downgrade from Mojave to High Sierra on my unsupported MacPro3,1. I tried downloading and installing the High Sierra patcher and just running it like I did the Mojave patcher but it will not create bootable USB. Also because my MacPro is an early 2008 that was running an unsupported macOS, I cannot access Recovery Mode. Please help!!!!
Aluminium Unibody Macbook 5.1 late 2008 does not work here (High Sierra was possible).Patcher tool 1.2.3 + Mojave 10.14.2Maybe its becuase of 10.14.2 as the latest patcher tool version is optimised for 10.14.1 ?Anybody here with same 10.14.2 problem?Or can someone tell me where to download a full 10.14.1 ??
Successful initial install of latest version on a Mac Mini 5.1 (2011) via USB flash drive. However, upon 2nd restart while holding option key to install patches, the Mac does not reboot, shows nothing on screen, and shuts down after a minute or less. Rebooting without holding option key shows circle/line icon and also shuts down after a minute.
NVIDIA would be launching their GeForce GTX 770 by the end of this month but there's some new information found by Videocardz which suggest that current GeForce GTX 680 GPUs can be flashed into the upcoming card.
The GeForce GTX 770 might be based on a different revision of the GK104-425 A2 but a reddit user found out that the card is actually a GeForce GTX 680 in disguise. The GeForce GTX 680 can easily be flashed to become the GTX 770 by using a custom BIOS from the GTX 770 board, here's what the user had to say:
By flashing the included BIOS (.bin) to your board, then dropping the included .inf file into the 320.00 driver package before installation... you too can have a GTX 770 weeks before it's released! Please note it has to be a 320.xx driver, as support for the 700 Series was added in the DLLs around this time. Reddit
So I have a Mac Pro 3.1 That I want to max out. I want to run Catalina, if possible, or Mac OS High Sierra, if that's better. I am not really sure what kind of gpu I want to use though. I've seen a people recomment the NVIDIA GTX 680, which is easy enoguh to flash, however, I also see that the ATI Radeon HD 5870 For Mac Pro is also good, though I don't know if that's compatible with my mac. Those are the 2 I'm going for right now, around the same price. Is there any other gpu you would recommend, or any advice about the two I mentioned?
I personally would flash the motherboard firmware to that of the 5,1 model. Then install a Mojave compatible GPU (AMD ones seem the best bet because of Apple native support) and install Mojave. The only hitch I have heard is that the Apple Store will still see your Mac as a 4,1 model and not let you download Mojave. If you know someone with a Mac that will download it, do so and make your USB installer stick. It should install just fine on your firmware upgraded Mac.
The Apple store wouldn't let me download Mojave directly to my 2009, had to download on another machine (a 10.13 Fusion VM) then create a bootable USB, boot my 2009 from the USB and install from there.
Yes, per the specifications macOS Mojave runs on a Mac Pro 2010 with a Metal-capable GPU. The software is unaware that your machine is really a 2009, as it only checks the board ID which matches a 5,1 machine. Currently running Beta 5 on my 2009, with an AMD Radeon R9 270X flashed with EFI firmware. Be sure to remove any other GPUs from the machine. I first had an issue then remembered I had my original GT 120 installed. I was required to update my EFI firmware, and it successfully updated to MP51.0089.B00. The firmware update may require a GPU with EFI firmware (gray boot screen.)
just nervously updated from High Sierra to Mojave on my Mac Pro early 2009 (4,1 flashed to 5,1. - dosdude patch for High Sierra ages ago - then the Mojave boot installer/patcher usb drive method by dosdude just last night..)
