MP 1,1-5,1 Manually Configured OpenCore on the Mac Pro

[hyphonic]

Uuuuuh, sorry that's what I have been afraid of. Added the hybridization like instructed on page one and had one complete machine-crash during Software-Update checking for updates and the next after the following hard reset during loading the login-screen (screen with artifacts, two times complete crash of the machine). Went back to my previous config file without hybridization and without the possibility to update.

I'm slightly stuck on trying to put 0.7.4 on my second 5,1 Mac Pro which has Mojave 10.14.6.

I'm fairly savvy with this (I have it running on my other Mac Pro), but this is the first time I'm getting this error when I run the bless command:

csrutil status is disabled. I have only the 1 disk drive in the machine now, just a single 1TB HDD.

Opencore is in the right location as well. My Google wizardry is failing me when I search for that.

I've checked and the structure from my disks is nearly the same as in the screenshot here:

Activate AMD hardware acceleration

Can you double check if you do everything right? Mount your EFI partition, and check if you can see something like the screen capture as per step 12. Most important, make sure you can see the identical file path as showed in that screen capture. 1580772940 I re-tested the command, it works...

I used these commands:
sudo diskutil mount /dev/disk0s1 (that worked)
sudo bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/OC/OpenCore.efi (that gives the error)

the same error occurred regardless of me typing it in or using the AppleScript provided in the package.

System report says:

I'm doing everything the same as for my other MP 5,1, they are nearly the same just that this one has an old 1TB hard drive and single CPU X5690. Both are RX580 graphics cards.

sudo diskutil mount /dev/disk0s1 (that worked)
sudo bless --mount /Volumes/EFI -setBoot --file /Volumes/EFI/EFI/OC/OpenCore.efi (that gives the error)

I don't think your syntax is correct, which means you are trying to bless the wrong path. You'd better study the details of post #1 and use the syntax recommended there.

sudo bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/OC/OpenCore.efi (that gives the error)

This differs from the description in post 1 in this thread. Why do you ask in this thread when you are following a different recipe?

Hi there, I can't manage to boot OpenCore but I think I've followed all the steps properly. Mac Pro 5,1 running macOS 10.9.5 here. I want to enable my GC-Titan Ridge 2.0 Thunderbolt card but the System Report still shows nothing under the Thunderbolt section?!

I've looked to see if OpenCore was booted properly and here's the error message I got, what could be the problem?

In the attached picture you'll see the mounted EFI partition with the proper files added to it and I think I set it to be bootable... please help!

^I don't know about those messages, but I think you need the following:
EFI/EFI/OC/ACPI/SSDT-TBOLT3.aml (this should be announced, within config.plist, at Root/ACPI/Add/0: Comment=TBOLT3 (or anything you like); Enabled=true; Path=SSDT-TBOLT3.aml

That's the way I have it and it works fine.

Sorry, I confused OpenCore with another package (linked from the first post in this thread). Indeed this was the wrong topic. Apologies. I found what was happening and it was unrelated to syntax.

My replies above can be removed.

My problem is to boot with OpenCore, it looks like it didn't worked because I'm getting an error message whenever I query the OpenCore version that should be loaded. Any hints anyone?

And Peter, on which macOS version are you? Are you confirming that this Thunderbolt add-on card works on macOS 10.9.5 once the system has booted with OpenCore?

Thanks a bunch everyone,
George

 

[PeterHolbrook]

I’m on 11.6, but I can confirm that my TB add-on card is recognized by Catalina, Mojave and, if I recall correctly, even High Sierra.

Is it one flashed for Mac or just out of the box?

 

[PeterHolbrook]

Flashed for Mac.

Anyone has issues with Airdrop?? I can receive in the Mac Pro 5.1 of my sign, but if I try to send to the iPhone, don't work... don't do nothing... OC 0.6.9 installed with SurPlus and last version of BigSur...

 

[Pressure]

Can anyone refresh my memory on how you add a SoftPowerPlayTable with OpenCore?

you have one EFI too much

 

[Cococollector]

i. e. one folder level (EFI - EFI - EFI) too much, that's what Macschrauber's trying to say

 

[cdf]

Here is the desired folder structure:

EFI system partition
└── EFI
⠀⠀⠀├── BOOT
⠀⠀⠀└── OC

Hi, I have Big Sur 11.6 with martin lo OC 7.3(v2) installed on nvme, I want to make a clean install on a normal SSD, can I just start a normal installation of the latest release ?

simple answer is yes.
Download full installer and make a USB installer and build OC to the USB stick.

 

[MacNB2]

simple answer is yes.

hmmm. Why the need to create a USB installer and build OC on the USB ??
If macOS is up and running on the NVMe, then one just needs to download the Big Sur Installer and run it.
It will then prompt you to choose the disk for the new installation. In this case, choose the new SSD (assuming it has been already formatted and ready for installation beforehand).
It will be quicker to install from NVMe to SSD than from USB to SSD.

Yes, even better!

As far as I can tell this doesn't work. I got caught between a rock a hard place so I decided to try it out and the closest this gets on my 12 core Mac Pro is a black screen before the boot picker.

 

[PeterHolbrook]

What do you mean, "this doesn't work"? OpenCore? Most of the people who have written on this thread are living proof that it works great. Perhaps there's something wrong with your hardware, or maybe you haven't followed the procedure of post #1.

Maybe try using the easy to install package linked in post one. (Martin's Package).

I have that 0.7.4 package running on two MP5,1s, a 12 core 128GB machine and a less powerful 6 core machine.

One thing I had to do in both occasions to get macOS 11.6 to install properly was NVRAM reset (before blessing). Once that was done it worked normally. Can you step by step explain what you did - probably some small thing.

I'm running x4 2012 5,1 and x1 mBp 2010 GT 330M using OCLP v0.3.0 and it works great!
I think you need to read up more and take your time and it should work.

Not trying to piss people off... I mean... The install procedure was straight forward if you've done this before.... I've gotten a previous version of OpenCore working with the legacy patcher previously on Catalina and 11.2.3 but from what I gathered this procedure could be accurately summarized like this (and it doesn't work).

Mount the EFI Partition of the drive where you want to install open core. Copy the OC and BOOT dirs to the EFI partition of the drive that is going to host OpenCore. Copy the provided config.plist to the OC directory. Bless the drive (if not already). Reset the PRAM three times and viola! You should get a boot picker! If you don't then validate the config.plist or install debug release and start wasting your life away trying to troubleshoot.

That is essentially what I did. The technical details of how I did it are probably tmi given I don't have a working installation of Mojave anymore so I modified directories on the target drive AdHoc from a 3rd party machine or from a bootable USB (that refuses to install Mojave...)

BackStory:
My hardware can't be the problem, I got this working on a previous version of OC running fine with 11.2.3 but I should also note that when I went to 11.3 (before the warnings came out) and I couldn't boot to it from OpenCore. Without a working Mojave installation I was stuck in a rock and a hard place. Once I upgraded the OpenCore dirs to 0.7.4 on my blessed target drive I lost the boot picker. So I've done everything I can to create an open core that is compatible with 11.6 in an attempt to boot to an install USB and reinstall 11.6. But I've managed to bork the OpenCore installation following this procedure, after already losing access to my 11.3 installation by upgrading macOS before upgrading OpenCore.

tl;dr
Either I'm missing an important configuration step in the config.plist or this method isn't a one size fits all solution for the Mac Pro 5,1 and there is something I need to add to the config.plist in order for this to work. Either way, I meant that "as presented" install procedure doesn't work to get from 0 to boot picker without any additional modification (besides setting boot picker value in plist.config to true). Clearly something is missing.
