MP 7,1 OpenCore on Mac Pro 7,1

[startergo]

Ok, i am currently watching the videos. Now that you made the EFI are there some parts that I can skip?

Just boot OC first to make sure it works and I will need the Path from bootcamp nothing else for now.

Shall I just follow this guide? https://dortania.github.io/OpenCore-Legacy-Patcher/BUILD.html

Ok so we tried making 6950xt work unsuccessfully:
So it reboots with this error:

It is kind of strange as it reboots at AppleNvme Assert failed (although this is probably misleading).
Anyone has any ideas? Attached is the 0.80 OC folder

Ok. I made 6950xt work in Monterey with an SSDT on a a x299 mobo. It should be possible for the Mac pro 7,1 or cMP to work too. So as a proof of concept spoofing device-id is enough.
Another solution is to add the device-id to the driver's plist.

Any updates to this? Did the end up returning his 6950xt?

He was supposed to come back to me but then he disappeared. No answers to my email. Hopefully he is ok at least.

Hi buddy, if we are talking about me then yes I am fine.. I just kinda gave up ! I still have the card and have time looking into it again now.

Hi Startergo, can I use this "EFI for real Macs" in my 7,1 for easy switching between Mac OS and Windows 11? Is there a specific opencore package for the 7.1? I have a rx6800xt and getting a 6900XT so don't need the spoofing for a 6950. Thanks

You can try the OC package without the SSDT spoofing. I am not sure I understand why you need OC in the first place? You can install and boot Windows 11 without OC. First install Bootcamp (Windows 10) and then upgrade to Windows 11 with the MCT.

Yeah, I have 11 running without bootcamp on an internal SSD in my 7,1 that used to be in my 5,1, I guess the best thing to do is just install Bootcamp drivers in Windows, I was afraid it might install the GPU drivers and mess with my AMD Adrenalin drivers. Just looking for the easiest way to switch between Mac OS and Windows as I used to use Opencore to do it in my 5,1.

Is your GPU not natively supported? That is, has a bootscreen? If so, you can set things up to always show this and then select from there. I would use RefindPlus in your shoes but a native GPU should also do the job.

Would actually like to get my hands on a log file from a RefindPlus run on MP71. Please let me know if willing to test (you should be able to run from the ESP on a USB stick for testing) and I will PM you to discuss the steps and send a trial build of RefindPlus.

I installed bootcamp drivers today, and all is good can now switch between Monterey and Windows 11. My GPU is a Sonnet RX6800XT but I get the boot screen in the 7,1. I pulled the W5500X MPX that came with the 7,1. I can run the refindPlus if you want.

Did you set things to use the BootCamp Assistant or did you just install the drivers?

If you used BCA, can you try running nvram -xp | grep BootCampHD?
This stores info used by AppleLegacyLoad on cMP and wonder whether BCA sets this on new Macs.
