Thanks so much!! Really appreciate your help!Depends, with the original GPU you are limited to High Sierra, and with some careful upgrades like a new AirPortExtreme and a METAL supported GPU, you can run Mojave/Catalina/Big Sur (at this moment limited to 11.2.3 release).
Thank you so much Macsonic!@DocMidi657 Congrats on getting a cMac Pro as a gift. If you plan to upgrade to Mojave, here is an excellent post about Mojave by Master Guru tsialex Just take note on some important details.
MP5,1: What you have to do to upgrade to Mojave (BootROM upgrade instructions thread)
Please fully read this first post, you will probably find that you have one or more problems described into the various notes below. Mojave will only install if you have upgraded your BootROM to the current release and your Mac Pro have a Metal capable GPU*. If you are trying to install Mojave...forums.macrumors.com
Thank you so much Macsonic!
Do NOT create a Fusion drive, it will be more trouble than it's worth.Wow - so I too have just obtained a Mac Pro 5.1 mid 2010 model with quad core xeon. Ive upgraded this to High Sierra and will be swapping out the HDD for an SSD and may create a fusion drive out of the two ....
Anyway thanks you this post. I currently have a iMac 13.2 which I run Monterey on via OCLP so I'm no stranger to this forum.
@DocMidi657 how did you get on with your upgrade ?
When Apple launched the FusionDrives it appeared to be an incredible idea, until Macs that had it from factory started fail because the NAND cells of the SSD part, where the write-caching for HDD is stored, started to die before one year.Do NOT create a Fusion drive, it will be more trouble than it's worth.
Just use a straight SSD (refer to the SSD wiki, there are some not compatible).
Ok… having seen your posted, I decided to NOT create a fusion drive in the end and just stick with the standard ssd as a boot drive. Works a treat. So now question is do I invest in a graphics card to push this higher than High Sierra or leave it alone.When Apple launched the FusionDrives it appeared to be an incredible idea, until Macs that had it from factory started fail because the NAND cells of the SSD part, where the write-caching for HDD is stored, started to die before one year.
Works wonderfully for some months, after that you need to replace the SSD. Back then Apple made FusionDrives with long endurance SLC NAND SSDs, imagine now with people using TLC/QLC drives…
GTX 760 is a Kepler card with METAL supported and works fine with OpenCore for pre-boot configuration support. Quadro 4000 is a Fermi card, without METAL. You can install up to BigSur with a Kepler card without major hacks and Monterey with the NVIDIA Big Sur drivers.Ok… having seen your posted, I decided to NOT create a fusion drive in the end and just stick with the standard ssd as a boot drive.

I’ve currently got 2 GPU’s current a GTX760 and a Quadro 4000 - both I believe are pc based cards so won’t give me a max boot screen. Contemplating if its worth swapping these two cards for a proper Mac Pro supported (or flashed) card with metal support… not sure where to get one of these tbf.
Is it worth updating the GPU and all the hassle that comes with it…. Would I use it if I did ? I’m not sure…
Sorry guys for rambling, just thinking out load ?
Forgive me if I am wrong.GTX 760 is a Kepler card with METAL supported and works fine with OpenCore for pre-boot configuration support. Quadro 4000 is a Fermi card, without METAL. You can install up to BigSur with a Kepler card without major hacks and Monterey with the NVIDIA Big Sur drivers.
I don't really like hacking Monterey again each time a new software update is released to have NVIDIA driver support again, so I only use NVIDIA GPUs up to BigSur.
There are Westmere quad-core Xeons, X5677 is the most common found one - but from factory you are correct, only Nehalem Xeons were sold by Apple.Forgive me if I am wrong.
I thought OpenCore did NOT work with a quad cMP....?
Which is what @steverae has.
Think I need to install the Kexts from bigsur for this card, I assumed OCLP would do this itself….Ok so i can get a picture on my monitor with my GTX 760 however,when ever i try to patch/load the Kepler drivers to make this work - i get a weird error in OCLP.
might bite the bullet and invest in a proper compatible card, going to go look and see what i can find.
thinking either the RX560 or the Radeon 79xx series
The 5770 works fine in mine just make sure to apply the patches from the SETTINGS section in OCLP.Thanks guys, might give the GTX 760 a try - I managed to get Monterey running on my Mac Pro 5,1 using OCLP. Graphics are a bit flaky due to the HD 5770 card but it works, I’ve been patching my iMac 13,2 with OCLP since bigsur with no issues…..
Let me see if I can post a pic of my Mac pro
Ok so expecting my Hd7950 Mac version to arrive any day now, this should be a big improvement over my hd5770.Think I need to install the Kexts from bigsur for this card, I assumed OCLP would do this itself….
anyway put in a offer for a hd7950 so we’ll see what happens
Ok so expecting my Hd7950 Mac version to arrive any day now, this should be a big improvement over my hd5770.
With the 5770 I see a lot of glitches in transparency even with all OCLP patches, unless I disable transparency in accessibility.
But we’ll see what the 7950 brings
I’ll post an update here
Just realised too thst my iMac 13,2 has the nvidea GTX 660m chip in, similar chip to what is in my other GTX 760 card, now on eBay
Anyway thanks for all the help guys - much appreciated
Watch this space
Have a Mac Pro 5,1, It is running macOS Sonoma 14.1.1 and it works perfect and installs like any operating system With Dartania OpenCore 1.2.1, Using a Nvidia GTX 780Ti or a GT 730 Video card, Both work every time with everything, Tried a Nvidia Quadro K5000, It works but the other two work way better with no problems at all, Also has a Sonnet USB 3.0 card and a WD Black NVME in a the PCIe slotThanks to all for this thread + subsequent contributions as they are all very informative and interesting. I also am the proud owner of a long running 5,1 and am slowly starting to see signs of app obselescance driven by system deprecation and am considering making the jump though i would only do so if i really fely i would gain a serious amount of years, not to have to get back inside the box within a year or 2.
I realise that the post higly stresses the importance of removing all non native drive bay locations (my system is currently running from a SSD in the old DVD drive bay using more than one OWC conversion kits, which work amazingly - so im guessing i will have to unplug them all and somehow get this drive into the the 1st of the drive bays on the standard HD array -
Additionally I have an RX 580 with 4 Meg of ram as my GPU - and am thinking this will work out and understand that i have to run it through the DVI port on an older screen to go through the steps succesfully.
Not sure when i will get started with this as I use this machine daily and it would no doubt set me back a full day + the uncertainty of seeing it actually all install succesfully will probably be the greatest mental obstacle keeping me from actually taking the first step in that direction.
Anwyay - i guess further obselescance (say a browser) will most likely be the greatest motivator.
If any of you Pro's have any words of wisdom to help me make the jump, it would be most appreciated !
Any dramas with Sonoma on that machine? Mine have Radeons (580 or RX6600XT).
To the original poster . . . if you really want you can install the current MacOS on your 2012 MacPro. With a few upgrades (a lot of them are much more affordable these days), you can have a decent setup on your rig to adequately run Sonoma 14.2
I used OpenCore Legacy Patcher 1.2.1 to install Sonoma 14.2 on my rig.
