The 2009 Mac Pro shares an identical motherboard with the 2010 model. With a firmware update, you can use newer CPUs and upgrade to macOS 10.12 and 10.13.

It is important to note that you will need an official Apple GPU installed while performing the flash, so go ahead and dig out that old GT120 that came with the system when you purchased it if you've upgraded to a non-official GPU in the meantime.

If you opted for a GPU upgrade from Apple at any point, you may have a different card. This could include:

• ATI Radeon 4870

• ATI Radeon 5770

• ATI Radeon 5870

Provided these are original Apple cards, you should be fine to proceed.

  1. First thing's first: You will want to upgrade to macOS 10.11, which is the latest "officially" supported version of macOS for the 4,1 Mac Pro. Provided you are on at least 10.6.6, you should be able to download the installer from the Mac App Store by following this link If you are on 10.6.5 or earlier, you will need to first upgrade via Software Update to the last release of Snow Leopard (10.6.8) to get access to the Mac App Store.

    • You will need to download two different packages to complete the upgrade:

    • Mac Pro EFI Update

    • Firmware Update Tool (hosted at Netkas in the bottom of the first post)

    Is there another place to download the tool? I can’t seem to connect to Netkas.

    Is there a way to work around it?

    I nolonger have the original - Réponse

    you just need to have a card with the original EFI from Apple- there’s some other cards around, like the Radeon 4870 for example. It may work with newer “compatible” cards like those from, but I’m not sure.

    • You'll need to disable System Integrity Protection (SIP) in order to flash the new firmware.

    • Restart your Mac Pro and hold cmd+r to boot into the recovery partition on your boot drive.

    • Once in Recovery Mode, go to the Utilities menu at the top of the screen and click Terminal

    • Enter the following command:

    • csrutil disable

    • Hit return and restart your Mac Pro as normal.

    This step only pertains to OS El Capitan and later

    Hi Nick,

    Based on your hardware profile, you have the very first Mac Pro, which I believe can be flashed from a 1,1 to a 2,1 - but I have not done that process myself so I am afraid I can’t speak to how it works. I believe this forum thread (also on Netkas) may have the information you need.

    • While the tool was originally designed to pull the firmware directly from Apple's website, a change in the file location and name on Apple's part has made it necessary to download & mount the .dmg prior to running the tool.

    • Double click the firmware file you downloaded in step one to mount the disk image to your desktop.

    • Right click and select "Open" on the firmware update tool. Since it is not signed with the proper certificate, macOS will likely refuse to open it just by double clicking the file. Right click the file and open from the menu to fix this.

    • You should have two options in the window - upgrade to 2010 firmware and downgrade to 2009 firmware. Only one option will be available at any given time, dependent on which firmware you have installed.

    • There is really no reason to ever downgrade to 2009 firmware, as none of those machines are still under any warranty from Apple and the system discs are not as important now that all OS versions are given as software downloads.

    • You are not required to upgrade your CPUs if you update to the 2010 firmware- your original system configuration will continue to operate as it always has.

    • Be sure to read any and all information that the utility may pop up.

    • IF YOU HAVE DIFFICULTY: Try using this alternate tool.

    I just tried this on my 2009 Mac Pro. Everthing seems to go according to plan. The helper utility runs, does it’s thing, then tells me to shutdown. But when I hold the power button to start back up and actually run the firmware update…. nothing happens. That is, it boots normally, no updater. I’ve held the button till if flashes, I’ve held the button till I got the tone. But no matter what, it just boots normally. This machine is running 10.9 btw.

    Any suggestions?

    Hi John, I’m not entirely sure - there’s some good discussion in this macrumors thread that may be of assistance. Also feel free to ask a question in the answers forum here- you will likely get some good responses!

    Step 2 says to run the firmware tool, but in Step 1 there are TWO firmware tools to download. Which of these do I run?? If both, which one goes first?

    david - Réponse

    Hi David,

    In the first step there is a tool for installing the firmware and the firmware itself- if you download just the .dmg on your 4,1 machine, it will refuse to install. You need the .app from Netkas, which is the second link. Download both, open the disk image from Apple, run the tool from the second download and it should auto detect the package on the desktop. Then it’s off to the races!

    • After the tool has finished its work, it will tell you to shut down your computer. Just perform a normal shut down procedure.

    • After your Mac Pro is powered off, hold the power button down until you see the power LED blink quickly or you hear an audible tone. The blinking LED will precede the tone.

    • Your computer should now begin to update the firmware on its own. You should see a gray screen with a progress bar at the bottom of the screen.

    • This is a different bar than you would normally see with macOS- the firmware updating bar will be a hollow rounded rectangle that slowly fills up, rather than just a bar that slowly gets longer as you would typically see.

    • Your computer may restart on its own again following the flash.

    I just can see the gray screen, there is no progress bar. Let me know the reason why! Thanx

    • Once your machine has rebooted to the desktop, it's time for the moment of truth.

    • Open About this Mac and click on System Report

    • It is worth noting that About this Mac will still report this as a Mac Pro (2009), even after a successful flash.

    • In System Report you should see a line in the first window labeled Model Identifier - if the firmware flash was successful, you should see Mac Pro5,1

    everything went as iterated; system report still shows 4,1.

    I couldn’t mount the updater by double or right clicking, so I moved it physically.

    the system will not allow me to return to reecovery mode.

    Ed Fiala - Réponse

    • Unless you have a compelling reason otherwise, you'll want to reenable SIP. Once again, you'll have to go into Recovery Mode just like you did before and open the Terminal.

    • Enter the following command

    • csrutil enable

    • Reboot the machine and let it load to the desktop. Open a new terminal window and enter the following command to check the status of SIP

    • csrutil status

    • If all was successful, you should get a line back that reads:

    • System Integrity Protection status: enabled.

    • And that's all there is! Now you should be able to upgrade the processors to a much wider swath of options.

once installed the firmware 5.1 can be updated in the installation of the new OS?

infoalessio100 - Réponse

Do you mean to update to 10.13? Yes, you can do that firmware update as well. It should work automatically.

Josh Calvetti -

Can you use a processor tray designed for a 2010-2012 model after the firmware update? Not inclined to actually replace the CPU chips.

BradMacPro - Réponse

I’ve heard conflicting reports- at the very least, if it does boot with a 2010 tray, my understanding is the fans will go crazy. I don’t think it’s recommended to swap trays between versions as they have a slightly different firmware and construction. Replacing the chips is pretty easy though, and we have a guide for that as well!

What restrictions are there if you no longer have an original Apple GPU? My MacPro has an ATI Radeon HD 4870 512 MB to drive my 30” Apple monitor.

Ronald Koontz - Réponse

We’re in a similar boat: I’ve got a Radeon HD 5770, purchased from Apple, driving a 30-inch Cinema Display. I got through both BIOS upgrades fine. Perhaps display adapters with non-Apple firmware cause problems.

Tom Yager -

A quick note that might save someone trouble: Following these well-crafted instructions, my Mac Pro kept booting to my OS (10.11) instead of the firmware updater. Starting over from a Lion (10.7) startup partition worked, and then I was able to return to 10.11 to do an in-place upgrade to High Sierra from the App Store. The second firmware update from the OS installer ran without issue.

Tom Yager -

Hi Ron, thanks for the info! You should still be okay with upgrading if your GPU is one of the upgrade picks Apple offered. I have amended the introduction to reflect this as well.

If memory serves, there were 3 other GPUs Apple offered as upgrades for the 09/10 model Mac Pro. These are the

• ATI Radeon 4870

• Radeon 5770

• Radeon 5870

Provided they’re all still official Apple cards, you should be okay to proceed.

Josh Calvetti -

It is safe to upgrade my MacPro4,1 with an NVIDIA GeForce GTX 680? Thanks.

suzzz -

You have a 4870 that doesn't have the Apple EFI? If it is a reference model card, it can be pretty easily flashed with Mac EFI (Apple boot screen). I have flashed these for 4 of my friends with good success.

Benjamin Dittman -

It is because if you have a non mac gpu as your primary card none of the mac os startup screen will be displayed. You would have no idea what the mac was doing while the firmware was installing (if it even was) and just have to sit looking at a black screen and hope that it completed correctly.

Shiva Parasram - Réponse

I completed the firmware upgrade successfully. Then installed High Sierra successfully. Now my AirPort card is not recognized!

I had installed a AP card I had laying around from another Mac laptop (I think) that I had scrapped. So, I think that since the High Sierra software is assuming that this is a 2010 Mac Pro that it would also only have the AP card that came with the 2010 models.

My theory is that it will need a newer AP card than what I have. I’m honestly not sure what year my current AP card is from. Is anyone else having this problem or figured out a solution. If not, I will probably try ordering a newer AP card to stick in it or run an ethernet cable to it.

So I’ve already updated my early 2009 Mac Pro running El Capitan to Mojave using a patch tool before I found this site and instructions. Put a new videocard in and – with the exception of not being able to use my second monitor for some reason (next fix to search) – is running beautifully. Curious if I would still be able to update the firmware to 5, 1 from 4, 1 even though Mojave is already installed and running? Wish I had found this earlier - would have saved time! Thank you in advance for your response.

Stu - Réponse

Hi @stu,

Hmm, I assume that’s dosdude’s patch tool? I’m not entirely sure though, I haven’t heard of anyone going to Mojave without flashing first. I’m not 100% sure if you can flash, but you should be able to in theory at least. The tricky bit is you’ll need the original GPU still installed to do the flash.

What firmware is your mac on at present? You can find it in System Information under the hardware overview- it’s labeled Boot ROM Version.

Josh Calvetti - Réponse

Hi Josh! It was dosdude’s patch tool that was used to install Mojave without flashing. Everything is running smoothly since installing a new video card - Radeon RX 570 - and even figured out the issue as to why the monitors were not working when using a displayport cable. Exactly what I was thinking, that in theory it should work and there’s no reason it should not but I have not found anyone who has attempted this.

I still have my original GPU which was an upgrade via Apple. It’s an ATI Radeon HD 4870. Trying to do as much research as possible before contemplating the firmware upgrade. I use this computer quite a bit for work so don’t want to end up with a very large cheese grater that does nothing.

My Boot ROM version is MP41.0081.B07. Thanks for responding and any insight/advice is welcome and much appreciated! Happy Friday!

I’ve upgraded. Few important things.

1) It must be latest EFI 1.4 on Mac Pro 4.1. Was 1.3. Have to upgrade first.

2) Literaly no cards (PCI) and devices other than Apple common. USB 3.0 card from Unitek forced upgrade to fail. Unmounted, no problem.

hi there please guys a little help here. i have that mac pro 2009 with original graphics card and every thing running os x 10.6.0 (snow leopard)

i have tried almost all the youtube tutorials on how to upgrade and flash firmware 4.1 to 5.1 but so far its been impossible.

one thing i have not been able to do on this mac is disable ISP, i have tried all the commands that may take me to the utility boot up screen by pressing command R and other combinations but nothing.

Then i heard a guy on YT that says before os x el capitan you dont need to do this, but i have a feeling he is wrong. still tried that way but nothing.

other guy said the command R combination on 10.6.0 is differerent back then if you want to get into the utility window up on boot up!, but could not fine a command combination before 10.6.0 to bring the utility window.


I WILL really appreciate any help or ideas guys thank you very much. from London

Frank - Réponse

Hi Frank,

The guy on YouTube is correct, System Integrity Protection (SIP) was a feature introduced in 2015 with El Capitan (v 10.11). I don’t remember exactly when the recovery partition came into existence, but I know that 10.6 definitely does not have it. What I would recommend is upgrading via Software Update to 10.6.8, and then once you have access the Mac App Store you should be able to get the last “supported” version of macOS, which would be El Capitan. [http://Get El Capitan|This link here] should let you download it from the Mac App Store.

Once you have El Capitan installed you should be able to follow the tutorial.

Josh Calvetti -

thank you #Josh Calvetti i will try your suggestion will try to download El capitan via software update ( i hOpe its still available for download , if not i will have to find it somewhere else ) and i guess once i install it, recovery partition will come into existence allowing me to disable ISP , fingers crossed cheers.

Hi Josh

Terry Lott - Réponse

No, it can definitely be done in El Capitan - that’s how I’ve done it a few times now. You just have to disable SIP with El Capitan, but the directions for that are in the first few steps. Hope it helps!

hi terry, I have seen a guy on YT do the firmware upgrade on Yosemite beacuse he could not do it on El capitan he said and worked ( will pass u the link should i find it ) i guess you should give it a go and see what happends, you have nothing to lose. ( Am not saying Josh is wrong by any means )

Now I have hit another wall, if u guys can help me…. am upgrading to El capitan from snow leopard to disable ISP to then again upgrade to sierra o mojave but when am installing el capitan i get a message saying ( THIS INSTALL COPY OF EL CAPITAN CANT BE VERIFIED, IT MAY BE CORRUPTED OR TAMPARED WITH DURING DOWNLOAD) .
