Le Mac Pro 2009 a la même carte mère que le modèle de 2010. Avec une mise à jour du firmware, vous pouvez utiliser des CPU plus récents et mettre à jour vers macOS 10.12 et 10.13

Il est important de noter que vous aurez besoin d'un GPU Apple officiel installé pendant que vous procédez au flash, donc allez-y et sortez ce vieux GT120 qui venait avec l'ordinateur quand vous l'avez acheté si vous l'avez changé pour un GPU non-officiel précédemment.

Si vous avez opté pour un changement de GPU faite par Apple auparavant, vous avez peut-être une carte différente. Il peut s'agir d'une des cartes suivantes:

• ATI Radeon 4870

• ATI Radeon 5770

• ATI Radeon 5870

Si ce sont des cartes d'origine Apple, ça devrait fonctionner.
Après avoir réalisé ces étapes, vous pourrez commencer à ajouter des RX 580, etc.

    • Tout d'abord : vous devez mettre à niveau le système en macOS 10.11, qui est la dernière version "officiellement" supportée par le Mac Pro 4,1.

    • Si le système en vigueur est 10.6.6 ou un plus récent, vous devrez pouvoir télécharger son logiciel d'installation depuis le Mac App Store à l'aide de ce lien.

    • Si vous disposez au mieux de Mac OS X 10.6.5 Snow Leopard, vous devrez le mettre à jour en version 10.6.8 à l'aide de Mise à jour de logiciels afin d'avoir accès au Mac App Store.

    • Vous aurez besoin de télécharger deux paquets d'installation différents pour effectuer la mise à niveau :

    • Mise à jour de l'EFI du Mac Pro

    • L'outil de mise à jour du Firmware (sur le forum Netkas, en bas du premier post)

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

    I had to change the above URL to that to make it work:

    This might work as a direct download too (from the linked forum page):

    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.

    Josh Calvetti -

    I no longer have the original Apple GPU. Instead, there is an ATI Radeon HD 4870 512 MB installed in my Mac Pro 4,1 (early 2009). I do get the startup and sign-in screens as the system boots. Is it safe to try the 5,1 firmware update?

    Mark - Réponse

    Mark, I have the same issue “This software is not supported on your system”. You found a fix?

    john - Réponse

    Mark, just got it sorted and flashed to 5.1. You must 1. put the “MacProEFIUpdate.dmg” on your desk top. 2. Unpack the “MacProEFIUpdate.dmg” by double clicking but DO NOT RUN the “MacProEFIUpdate.pkg”, leave it open on your desktop 3. The MacProEFIUpdate.pkg will be read by the “Mac Pro 2009-2010 Firmware” when you run that. 4. Run the “Mac Pro 2009-2010 Firmware” and follow the instructions, easy. Good luck.

    • Vous aurez besoin de désactiver le System Integrity Protection (SIP) pour flasher le nouveau firmware.

    • Redémarrez votre Mac Pro et maintenez cmd+r pour démarrer sur la partition de récupération de votre disque de démarrage.

    @josh is correct above that it’s a different procedure for your Mac Pro 1,1. Specifically to answer your question—if you’re still wondering, or for anyone else looking at this—System Integrity Protection was introduced in OS X 10.11 El Capitan. The csrutil command is meaningless for earlier versions, hence your “bad command” error. This can be checked without recovery mode by running csrutil status in Terminal.

    Richard Graham -

    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.

    Mark - Réponse

    I have a Mac Pro 4,1 running El Capitan. I followed the instruction in Step 2 to disable SIP but at the end, when I reboot the machine, it got stuck at the boot screen (Apple logo and progress bar). The only way out is physically powering down the machine, do a NVRAM reset and only then it can reboot back to El Capitan. But the SIP is enabled again by the NVRAM reset! :-( . I tried a dozen times or so. but no joy. Advice from any one?

    Hal Nguyen - Réponse

    Running 10.11.6 on a Mac Pro (Early 2009) and cmd+r does not go into recovery mode. Any tips to disable SIP? I was able to download the two files but if I can’t disable the SIP, I don’t want to waste time moving forward. Thanks in advance!

    I just ordered a new Backplane Board Mac Pro Early 2009 Not thinking about the firmware update ? Will the Mac Pro run with the 6 cores processors before I can flash the board the board to 5.1 ??? Ho gee wiz. I don’t have the old processors I bought it flashed and upgraded.

    I just hoping I might prepare everything prior to switching the board and then restart holding the power button ? Would that even work ?

    This board works Im typing on it. Its just that it had two voltage sensor that I just count fix is I decided to get a new 4.1 board cheap cheap ?

    I have problems installing El Capitan and tried to flash it with 10.8.5 there is no system integrity protection.. it did not work and was back at the old firmware after restart any tips here? Is a super user required? Maybe this can work on older Mac OS…?

    Dominik luedtke - Réponse

    @tobiasfunke, were you able to get into recovery mode using cmd+r? I’m having the same difficulty getting into recovery mode

    Tony - Réponse

    @tony NO. Still trying to get it done. I have 3 other drives in the bays so someone suggested to pull the other drives and leave one drive. I have not taken the time to do so thanks to work, life, family, etc.…. Alternatively, I may try to just put a new drive in and have nothing on it but the OS and then try. My issue is that I need to put my think cap on as how to do this.

    It is is very odd and I do not understand why it is so difficult. I am assuming that if I update the firmware, then switching drives back into the system will not matter as the firmware will not reset. I am a techie but not a superstar (in other words, I know enough to be dangerous and can solve matters but am not in the computer field). We will see. If you find a solution, please post and copy me!!! Good luck!!!

    I found a video on YouTube and the owner of the video was responsive and tried to help me thus the removal of the hard drives was suggested. It is here:

    • Alors que l'outil a été conçu à l'origine pour récupérer le firmware directement depuis le site d'Apple, un changement dans le répertoire du fichier et dans le nom nécessite de télécharger et de monter le .dmg avant de démarrer l'outil

    • Double-cliquez sur le fichier du firmware que vous avez téléchargé dans la première étape pour monter l'image sur votre bureau.

    • Faites un clic-droit et cliquez sur "Ouvrir" sur l'outil de mise à jour de firmware. Vu qu'il n'est pas signé avec le bon certificat, macOS va souvent refuser de l'ouvrir en double-cliquant sur le fichier. Faites un clic-droit sur le fichier et ouvrez-le depuis le menu pour régler ça.

    • Vous devez avoir deux options dans la fenêtre - mettre à jour vers le firmware de 2010 et revenir au firmware de 2009. Seule une option sera disponible en fonction du firmware que vous avez installé.

    • Il n'y a pas vraiment de raison pour revenir au firmware du 2009, vu qu'aucune de ces machines n'est encore sous garantie d'Apple et que les disques de réinstallation ne sont plus aussi importants maintenant que toutes les versions de l'OS sont disponibles en téléchargement logiciel.

    • Vous n'avez pas besoin de mettre à jour votre CPU si vous mettez à jour vers le firmware du 2010 - votre configuration système d'origine continuera de fonctionner comme elle l'a toujours fait.

    • Assurez-vous de lire chaque information que l'utilitaire peur afficher.

    • EN CAS DE DIFFICULTÉ : Essayez cet outil alternatif.

    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?

    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!

    • Une fois que l'outil a fini son travail, il va vous demander d'éteindre votre ordinateur. Faites juste un arrêt normal.

    • Après que votre Mac Pro se soit éteint, maintenez enfoncé le bouton d'allumage jusqu'à ce que vous voyez la LED d'alimentation ou que vous entendiez un bip. La LED clignotante précédera le bip.

    • Votre ordinateur devrait maintenant commencer à mettre à jour son firmware tout seul. Vous devrez voir un écran gris et une barre de progression en bas de l'écran.

    • C'est une barre différente par rapport à celle que vous voyez normalement lors du démarrage de macOS - la barre de mise à jour du firmware prend la forme d'un rectangle arrondi qui va lentement se remplir, plutôt que la fine barre qui s'agrandit et dont on a l'habitude.

    • Votre ordinateur devrait redémarrer tout seul une fois le flashage effectué.

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

    f22lingu - Réponse

    • Une fois que votre machine a redémarré sur le bureau, c'est le moment de vérité.

    • Ouvrez A propos de ce Mac et cliquez sur Rapport Système…

    • A propos de ce Mac le marquera toujours comme un Mac Pro (2009), même après un flash réussi.

    • Dans Informations Système, vous devriez voir une ligne dans la première fenêtre intitulée Identifiant du modèle - si le flash du firmware est un succès, vous devrez voir MacPro5,1

    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.

    • Sauf si il y a une raison importante, sinon vous voudrez réactiver le SIP. Encore une fois, vous devrez retourner dans le Mode de Récupération comme vous avez fait avant et ouvrir le Terminal.

    • Entrez la commande suivante

    • csrutil enable

    • Re-démarrez la machine et laissez-la charger le bureau. Ouvrez une nouvelle fenêtre du Terminal et entrez la commande suivante pour vérifier le statut du SIP

    • csrutil status

    • Si tout est bon, vous devrez avoir une ligne en retour qui dit:

    • System Integrity Protection status: enabled.

    • Et c'est tout ce qu'il y a faire ! Vous devriez maintenant pouvoir mettre à jour les processeurs avec un éventail d'options beaucoup plus large.

    Gone through all the steps and it appears to have worked. Says finished and tells me to power off then hold power button… etc

    However it doesn’t run the flash update, just restarts in OS.

    Problem I have is different SMC for System and tray, System is 1.39F5 & processor tray is 1.39F11 and identifier at 4.1.

    Hello, thank you Mr. Calvetti for the time you have dedicated to this guide, and I wanted to ask you a couple of questions about a strange behavior of the updater, that maybe you have already experienced and maybe you can give me an explanation.

    I follow the procedure step by step, I mount the pakage firmware, I launch the upgrade tool, it creates the ramdisc, it performs the patches, it updates the target folders, I turn off the mac, I turn it on again following the procedure, the led blinks, the tone is heard, it performs the particular boot, the update procedure starts, but it immediately performs a reboot, and does not perform any update, can you give me some suggestions.

    Thank you in advance

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!

Josh Calvetti -

Fans go crazy, There are two SMC chips on MacPro. One of them is on the backplate and the other one is on the cpu tray. In order to run MacPro smoothly, SMC chips needs to be synced upon boot. If they can not sync then the fans go crazy. You need to swap the TC4424P SMC chip on the 2009 cpu tray with the TC4424P SMC chip on the 2010-2012 cpu tray. This job needs top soldering skills!!. If you manage to do that then the SMC chips will be in sync and the MacPro will run smoothly. I did it with my 2009 MacPro 4.1 with 2009 4 core cpu and upgraded it to a 2009 MacPro 5.1 with 2012 12 core cpu. Also after the job done, I soldered remaining SMC from the 2012 cpu tray to my 2009 cpu tray with no SMC on it. After that it was a perfectly working 2012 cpu tray. Gave the tray to a friend who needs a 2012 cpu tray for his 2012 MacPro. He still uses that and I still use mine. You just need to find someone with top soldering skills if you don’t have any.

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!

This worked for me on El Capitan:

2. under “Allow apps downloaded from:” select “Anywhere” (**you may need to click the lock at the bottom left and enter your admin password to change these settings**)

3. at the prompt, click “Allow From Anywhere” to confirm your choice

A couple years ago I bought what I thought was a 2012 5,1 machine, but it’s apparently a flashed 2009 model (About this Mac says mid 2009, and system information lists the Model Identifier as MacPro5,1, Boot ROM MP51.007F.B03). The machine will not upgrade past OS 10.10, or at least the App Store won’t serve me the upgrade files). I’m wondering if there’s any benefit to trying this procedure. Any other suggestions?

Thanks in advance

I have a PCI-E card for Apogee audio that worked before and now doesn’t. Also noticed that 2 of the ram slots stopped working.? do I need to go back, remove the cards, re upgrade, then put back everything,, also a 5 terabyte drive won’t reinitialize? Thanks

I’m having an issue that I don’t see mentioned. I have an ‘09 I’ve tried this process several times and it doesn’t seems to want to work. I downloaded the EFI update and the firmware tool. I have followed all the instructions every time but I still have a 4,1 computer. I get to the restart after the blinking power light and tone. It seems like the grey screen flashes for just a second but then stops then restarts and when the computer is back on fully it’s still a 4,1. Anyone have an ideas?

Tyler Hoover - Réponse

Okay so I got no answers but I ended up figuring out myself. I realized that my computer needed the 1.4 EFI update before it could get the 1.5 EFI update provided here for the tool to work and everything to switch over to the 5,1

Tyler Hoover -

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.

3) After procedure have to reset PRAM (cmd+alt+P+R on restart). Without this 1333 MHz RAM modules are recognized as 1066 MHz

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.

Frank -

Hi Josh

I’ve read that the firmware upgrade can’t be done in El Capitan, and that the os needs to be dropped to a previous version. Is that the case? If so , why is that?


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!

Josh Calvetti -

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) . I HAVE DOWNloaded El capitan from and did a bootable usb drive TO load from but keep getting that message! HELPPPPP

hello guys : is it possible to clone my SSD running on el capitan on a macbook pro mid 2010 13 inch to install it on my 2009 mac pro 4,1 ??? the reason is that i would like to upgrade my graphics card , processor and ram???? instead of going hitting a wall every time i try to do it manually like in this tuttorial which i cant ( something always goes wrong and not able to install ) and then throw in the compatible components i have just mention thank you !!!!!

Hi everybody! I've installed dosdude patched High Sierra in my Mac Pro 4.1 (Early 2009), Logic Pro and many plugins with libraries installed in a secondary HDD. Now I would upgrade to firmware 5.1 and install new cpu to add cores to my machine. Two options:

1. new HDD with El Captain to run Firmware Upgrade tool and update at 5.1. Then a fresh install with a big work to reinstall system and all plugins !

2. After the firmware update with El Captain (installed in a EFI partition of HDD), can I restore my Time Machine backup with the dosdude High Sierra and then uninstall the dosdude patch with uninstall tool? Can this patched High Sierra recognize and run the new firmware to install new cpu?

Any advice... is welcome ! Thank you for support !

I am missing something with these instructions. After disabling SIP it request in STEP 3 that you run the Firmware tool and I presume that this is is the Firmware UpdateTool that you downloaded. What about the MacPro EFI update, what happens with this since there appears to be no mention of it in these instructions?

Hi and thanks for the tutorial!

As someone who is not experienced at all, I have to ask about the Apple GPUs. I don’t have the original graphics card available, installed is a NVIDIA Quadro FX4800 for Mac. Alternatively I have a ATI Radeon HD3870 from an old 3,1 available.

Would those cards be working as well or should I try to get my hands on a GT120 or one of the newer Radeon models mentioned in the article?

I just upgraded my early 2009 MacPro and this worked flawlessly.

One note for the wireless keyboard users out there with problems entering recovery - just wait until you see the grey screen after the startup chime, count to 3 and then press CMD(Win on Windows keyboards)+R.

I found out there is a delay for USB keyboard activation while using a wired keyboard with background lightning. As soon as the light turned on, I could press the keys and they got recognized. Then I used the same delay with a wireless usb keyboard and - tadaa - it worked like a charm.

2009 Nehalem Mac Pro users, know this! (comment 1)

This upgrade to 5,1 model firmware causes an audio playback problem that involves Line Out. (other outputs not tested but likely the same)

For those like myself that are recording studios that record directly to uncompressed audio files (AIFF) as do most studios, the playback on a 2009 Mac Pro is failed with a twist.

The twist is… all plays back perfectly until you go past Mojave 10.14.3.

Mojave 10.14.4 and above including Catalina patches all fail to “properly” playback AIFF files.

Perhaps a simple statement helps more, if you buy a standard factory CD (not mp3) at Walmart and try to play it on your firmware modified 2009 Mac Pro running the latest version of Mojave, it will “sound like” a dirty cd, a failing optical drive or some other typical problem, it’s not typical at all and nothing is wrong.

ALL…. AIFF files tested fail to play back properly with Quick View, Quicktime 7 Pro, iTunes, Apple DVD Player, and Quicktime 10 although QT10 is 99% useable.

Robert Boyle - Réponse

2009 Nehalem Mac Pro users, know this! (comment 2)

It sounds like a disk skip even if the AIFF file is on a drive.

Before the arguments begin… this has been verified on two entirely separate different 2009 Macs with “every possible” means of verification available.

It is 100% verified, the problem is the firmware.

Just to make certain, a “beyond extensive test” was also performed.

A version of Mojave 10.14.6 on a HFS+/GUID drive was created and booted on a totally unmodified 2009 Mac Pro. (works very well by the way)

Both 2010 and 2012 Mac Pro were also tested using the HFS+/GUID Mojave drive.

Those Mac Pros with no firmware modifications played back AIFF files without flaw.

Then…. 2010 and 2012 and 2013 Mac Pros were tested also without firmware modification, (because they don’t need any), and had no trouble with AIFF file playback using any version of Mojave on APFS drives. (still waiting to test Catalina and Big Sur)

Robert Boyle - Réponse

2009 Nehalem Mac Pro users, know this! (comment 3)

Nobody noticed this because most people do not own recording studios and all their music is bandwidth limited compressed garbage, and very few use or buy CD’s anymore.

Bottom line, 2009 Mac Pros using the updated 2010 firmware will have uncompressed audio file (AIFF) playback problems if using anything past Mojave 10.14.3. (read that again and let it sink in)

Compressed audio files play back just fine.

The only solution to this problem is to update to Mojave using the firmware modifications, then create an HFS+ GUID version of Mojave, then return the firmware back to 2009 / 4,1 and run the HFs+/GUID Mojave drive. (NOTE: Software Update will not update a HFS+/GUID version of Mojave)


Knowledge of Mojave requirements is assumed.

I tried dosdude Mojave legacy audio patches but did not test dosdude full Mojave patched installs because those require that firmware not be modified.

I ‘ve a Mac Pro 2009 4,1 dual processor, upgraded to 5,1 and got two x5680, I’ve done everything by the book and a clean reinstall of High Sierra. Problem is both processors - mac will start but I get nothing, no chime, no signal, only fans, one processor in CPU A machine will start and fan fans will go full blast. Diag led lights, all good, no blinking, no red.

I ‘ve tried (I think) everything possible, reinstalled both old processors and same thing, two processors i get nothing, one processor fans full blast but the rest ok. I have tried pram, smc, nvram and all resets. I have taken the whole mac apart, cleaned it, checked for damaged chips, components and such, and still nothing.

Firmware von 2009 Mac Pro Anfang 2009 4,1 auf 5.1

Hi, ich habe Schwierigkeiten, das update zu machen. Ich habe den Mac Pro mit cmd+r so gestartet wie beschrieben und im Terminal csrutil disable eingegeben. Dann neu gestartet. Dann bauten sich alle Grafiken langsam auf. Also in irgend einem Modus war ich. Ich startete den Firmwareupdater. Nach ein paar Sekunden kam die Fehlermeldung 5570.

Dann öffnete ich wiederrum das Terminal, um zu sehen, ob wirklich SIP deaktiviert ist. Mit csrutil status bekam ich enable. Ich nehme an, wenn SIP wirklich deaktiviert gewesen wäre, würde dort disabled stehen.

Ich vermute, dies ist das Problem, dass ich beim Firmwareupdate immer diese Fehlermeldung bekomme.

Grafikkarte habe ich auch die alte eingebaut: ATI Radeon 4870

Speicher sind 128 GB drin. Das sollte ja vermutlich keine Rolle spielen. Als Festplatte habe ich 4 x 1TB SSDs im Raid0, um 4k Videos zu schneiden.

Hatte jemand das gleiche Problem und kann mir helfen, wie ich das Firmupdate machen kann?

@figone1995 Nope, sorry- this is only for the towers, as they have a very different architecture than the laptops.

Josh Calvetti -

Maybe are you doing a confusion between upgrading hardware firmware and upgrading operating system.

Like explained earlier, MacBook Pro 15” Mid 2009 is a laptop, while Mac Pro 2009 is a tower Mac.

OS X 10.11.6 El Capitan is the latest OS X supported on this model officially.

You have 2 solutions :

- Purchase a new Mac, or

- Install a patched system for an unsupported Mac, if you have an adventurer. ;-)

A large enthusiasts community developed patchers for many OS X versions past El Capitan.

But the best range of unsupported system patcher affordable for your MacBook Pro model is from 10.12 Sierra to 10.14 Mojave.

Search for "unsupported Mac patchers" with your favorite search engine.

Last advice: do your first install trials on an external drive in order to learn how it works, An 16GB USB thumb drive is required to create the installer patcher, whatever the system chosen.

Good luck, if you choose the follow the adventure track. Do it at your own risk…
