1. double click original firmware from apple and mount DO NOT CONTINUE TO INSTALL PKG
2. double click 5.1 firmware tool and follow instructions to upgrade to 5.1
3. once RAMDISK is created, follow instructions to shut down mac
4. start mac and hold down power button until you hear an audible dong and release power button
5. firmware will now install, wait until mac restarts itself.
6. enjoy 5.1 and download Sierra!
Here is the link to download the firmware updater
You need to do this if you are running El Capitan first before doing the firmware update.
1. Click the menu.
2. Select Restart…
3. Hold down command-R to boot into the Recovery System.
4. Click the Utilities menu and select Terminal.
5. Type csrutil disable and press return.
6. Close the Terminal app.
7. Click the menu and select Restart….
If you decide later you want to re-engage SIP (and I earnestly hope that you do), repeat these steps, changing csrutil disable to csrutil enable instead.
download and use at your own risk and follow the on screen instructions. Run it off your internal system drive with nothing connected to your mac but mouse, keyboard, monitor and have the original mac video card installed that came with your 2009 mac pro.
This installer came from www.netkas.org I recommend joining and getting it from the original source instaed of my link above.
You will learn a lot from others who have done the install and have upgraded their macpros in by joining the forums there.
All credits too MacEFIRom for creating this firmware updater.
Important: The update may take a few minutes. Do not unplug, shutdown, restart or disturb your computer while the update is taking place and follow the onscreen instructions.
NOTE FOR THOSE WITH THE 5570 ERROR fix is below.
this is 5570 error fix. UPDATE: Solved by downloading manually firmware EFI 1.5 for from https://support.apple.com/kb/DL1321?locale=cs_CZ, mounting DMG (not installing PKG inside). Then run firmware upgrade tool and it ok now. thanks to Russell Smith for posting this below.
Also after the firmware update, if you installed new 1333 ram in your mac pro you need to ZAP your PRAM to get the faster ram to show up. To ZAP your PRAM start up your Mac Pro and before you hear the boot chime hold down the “command”, “option”, “p” and “r” keys all at the same time, continue holding them down until you hear the boot chime a second time, it may take 15-20 seconds then let up on the keys and the Mac will now show you have the 1333 ram installed.
