As I found out when I went to download Sierra, my Mac Pro has been dropped from the list of Macs that will run Sierra. I have read here in the various forums that the Mac Pro can be "Flashed" with a newer software. As far as I can tell my Mac Pro is also known as a 4,1 and I guess it can be flashed with 5,1 software. I have upgraded the CPUs to two 3.32 GHz Quad Core Xeon CPU's, and I currently have 24 GB of Ram. I have three NVIDIA GeForce GT 120 512MB graphics cards of which I cam using one with two monitors.

My question is this; Would flashing my Early 2009 Mac Pro with 5,1 software make it qualify to run Sierra? Would the flashing make it appear as a 2010 or maybe a 2012 Mac Pro?

I think I can find a thread that explains how to flash the Mac Pro and probably a link to the 5,1 software, but I have not been able to determine why I would want to, unless it allows me to load Sierra, and then I would attempt it.

I am also trying to find information on Graphics cards for this Mac Pro, I assume there are better alternatives to the current ones I am using.

The short answer is YES.

I would recommend a new wifi card that supports the AC standard as well as bluetooth 4.0 though.

Many features of Sierra depend on that but if you don't need stuff like Conutinity you wouldn't even need a new card.

Thank you for your fast response. Thank you for the link. I will look into the WiFi card/Bluetooth card. I also will now go search for the HOW of flashing and the 5,1 software as well. This is good news to me, I really did not want to begin searching for another Mac Pro, although I am sure I eventually will, probably next year around this time.

Start your MacPro into recovery mode via Command+R

From Utilities choose Terminal and type "csrutil disable" into the terminal window and press enter...

This will disable System Integrity Protection so you can change the firmware.

Restart your Mac.

Download the PATCHED firmware upgrade tool here: http://forum.netkas.org/index.php/topic,852.msg31640.html#msg31640

Start the firmware tool... it will download the necessary 5,1 firmware directly from Apples server and prepare the installation.

After the firmware tool is done, SHUT DOWN your Mac Pro.

When the Mac Pro is completely turned off... click the power button and don't let go, just keep pressing.

The Mac will make a long beep, now you can let go the power button and the firmware will update.

After everything is done, don't forget to re-enable SIP via recovery mode -> Terminal -> "csrutil enable"

Yes, your Mac Pro will able to install and run Sierra natively after 5,1 firmware flash. However, it will still identify itself as 2009.

The 5,1 firmware makes your Mac Pro

1) able to install better CPU (up to X5690)
2) able to run the RAM at 1333MHz (with the correct CPU installed)
3) able to get audio via HDMI / mDP (with 3rd part kext installed)
4) able to run Sierra natively (you can still use work around to install and Sierra without the firmware hack)

There are plenty of thread / info here about GPU. Just do your own study and decide which one fit your needs. Anyway, the good news is almost any card will perform better (or much better) then the GT120.

I have a Mac Pro 4,1 with the 5,1 firmware update, (and luckily I have the Atheros Airport Extreme wifi card too). I installed Sierra on an external drive and everything is working fine. Check your System Report results to see which wifi card you have, if it's also Atheros, you're good to go after the 5,1 firmware update.
 
I installed sierra on my hacked 4,1 tonight. So far so good. Will do some more testing tomorrow, and try to track down a wifi/Bluetooth card to enable watch unlocking.

Interesting quirk I found. If you instruct Siri to "go to sleep" it responds along the lines of "I never sleep", but if you say "put the computer to sleep" it does. :rolleyes:
 
I have an '09 MacPro but without the airport card and with bluetooth. Also Apple replaced the logic board some years ago and so current firmware ends with ....08 indicating refurbished. Will the 5.1 firmware update still work and will my original bluetooth work without a newer bluetooth hardware card?

My 4,1 also doesn't have Wi-Fi card (yet), Sierra can run without any problem. However, due to no Wi-Fi, all location base service cannot be used (e.g. Check weather via Siri), and of course, no Airdrop etc.

B08 is not a problem, still can be flashed to 5,1. However, no downgrade route.

Thank You for the information. As for #1, I thought that when I installed the two Quad Core 3.33 MHz processors that my Mac Pro had gone as far as it can in the processor options. Obvious to me now I was mistaken. I have no real feel for how much more I can get out of this Mac.

#2, I did not know there was any control over the clock speed of the RAM. Apparently there is based on your information, but it depends on 5,1 firmware, and a certain CPU. More searching for me.

#3 I will honestly say I have no idea what this is. I know what HDMI is but the rest is new.

#4 was my goal when I asked for help. I have to do the flash, and I also have to install a new WiFi card as well. I have not ordered it as they want me to select an additional antenna, and I do not know what I need. I emailed them and asked, but no answer as of yet.

Right now I am struggling with what I assume is a graphics card problem and after I get it flashed and Sierra running I will look for a graphics card. I am using Autodesk 123D Design to design a 3D printer with about a one half cubic meter build area. I did a "select all" in the main drawing and it took one hour, nine minutes and 38 seconds to accomplish this. So I wonder if 123D does not use all 8 cores, or does the problem come from an overwhelmed graphics card.

Again, thanks for your response. I am learning Mac all over again. I was up on all things Mac until I bought the sealed box called iMac. Now I have another Mac I can get into and I have to learn about its architecture
and what I can and cannot do with it.

No, you can't control it, but the system will automatically pick the fastest speed it can run. e.g. If you put a 1333MHz RAM in your mac now, it will only run at 1066MHz. But after the firmware upgrade, and a CPU upgrade, it will automatically go to 1333MHz if possible. No control from the user (at most, a PRAM reset to let the system re-detect the max speed).
 
Hi, sorry if this is a dumb question but can this be used on a late 2008 Macbook (aluminum - but not a pro)? It's been upgraded to 8GB of ram and has a 160GB SSD drive but I've not had anything else upgraded on it. It's currently running El Capitan without issue.

The laptop is currently identified as a MacBook5,1

Many thanks!!!

What about Bluetooth functionality? I use a Bluetooth mouse so need that. Don't care about those other features.

If by this you mean the firmware update? No, you can't use this firmware update on your machine. The update is for the 2009 Mac Pro desktop (not Macbook Pro) only. To my knowledge, there are no firmware updates like this available for other machines. The reason this hack was possible was because the 2009 Mac Pro and 2010 Mac Pro contained identical base hardware.

Having said that, there might be a way to get Sierra to install on your 2008 Macbook. Non-firmware workarounds have existed for other machines and other OS updates. You'll have to do some searching around the forums here.

Hi thanks, for the update :) and for clarifying on the firmware standpoint.

Looks like the dosdude1 work-around will have to be my route!

I would like to thank you for your help. I flashed the firmware this morning, and am now running Sierra on my, now 5,1, 2009 Mac Pro. All seems to be working fine. Time will tell if everything as in software and hardware are still functioning, I have only had Sierra running for about an hour.

Not sure how to end a thread, but I would like to also thank every one for their help. My next task is to find a better video card. I figure that my NVIDIA GeForce GT 120 512MB graphics cards are probably the bottle neck with graphic intensive applications.
 
Coalescing some important bits for Avoiding Error 5570
1) Turn SIP off or use an OS that does not have SIP, 10.9 or 10.10
2) Make sure your the firmware is at MP41.0081.B07download and run (Mac Pro EFI Firmware Update 1.4 - https://support.apple.com/kb/dl989?locale=en_US)
3) Run the tool
4) The download locations changed, so the update on netkas tool fails to download the Mac Pro EFI 1.5 update (if you look at EIF2010.dmg it is an HTML error message), download it here: Mac Pro EFI Firmware Update 1.5 - https://support.apple.com/kb/dl1321?locale=en_US

5) Rename the download to EFI2010.dmg and copy into /Volumes/RamDisk overwriting the failed download

6) Now open Terminal, type in: sudo <drag in UpgradeEFI2009-2010.sh>, press Return
7) Enter your password and press return

There will be a bunch of output, note any errors (ensure SIP is disabled because it copies files to /System)

8) Shutdown your Mac, then press and hold the Power button until it starts blinking, then let go
9) Do not disturb while the EFI update is in progress

If it happens FAST then it something didn't go right, it should take a minute or two

When you reboot, go to System Profiler and check your "Boot ROM Version" it should be MP51.007F.B03

I have also successfully installed High Sierra which must run another Firmware update before it will install, High Sierra 10.13.2 will install EFI Boot ROM MP51.0084.B00
