The dosdude1 patch can get the MP3,1 running 10.13 GM candidate with APFS on a retrofitted SSD but only with either an HD2600 or GeForce GT8800 card installed.  All later cards and even those from Apple such as the HD5770 and 5870 seem to refuse to boot even with a helper card in place.  The issue seems to be that Apple has rewritten the kext drivers for later AMD cards to depend on the CPU supporting SSE4.2, which the Intel Xeons in the 3,1 do not support. Presumably this was done to implement Metal 2.
There is speculation that the nVidia drivers do not have this dependence on SSE4.2, so efi-flashed nVidia cards might still boot. Has anybody with a MP 3,1 running 10.13 had success with a later efi-flashed nVidia card of any series from the last 3 or 4 years?

I agree with h9826790.

Remove all other hard drives & external USB memory until after the firmware flash

Do a clean Mavericks 10.9.5 install to an empty HDD.

Put the Apple firmwae update DMG on your user root folder ( the updater will look for it there )


Do a PRAM reset.

After the PRAM reset, boot from the EFI R9 280X holding down the power button until you either hear a long tone or see the LEDs flashing.

^^^^Worked for everyone else.  You need to read this page of this thread:,852.1140.html

And an EFI GPU is a requirement.


Hi there,

I have an old GT 120 with mac EFI (it is EFI, right?). Can I upgrade my mac pro's (native 2010) firmware?

Yes, it's native 5,1.

I'm on MP51.88Z.007F.B03.1010071432

If you sure everything you've done are correct. Try to boot from another HDD.

There are some reports about a particular HDD can cause no firmware update. Reason is unknown. But it clearly affected the 4,1 to 5,1 flashing tool. May be it can affect the native Apple firmware as well.

Mine is Intel DC S3500 SSD 300 GB with small BootCamp partition on it.

I suggest you get a blank HDD, connect it via the native SATA 2 port, install Mavericks on it. Then boot it with a Mac EFI GPU then try again.

Thats normal.  You have to power it back on and keep holding the power button  until you see the power light start to flicker and hear the  beep sound. After that the  firmware update will start. Don't turn off your Mac Pro at any moment it will turn off by itself.  

I did that and it just normally booted the OS despite that special beep and holding the power button.

I need to wait for the final version.

Do you have the 5,1 firmware now? What's you actually boot ROM version?
