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

I have been through Step 2 and I have the graphical boot loader now (I tried flipping the switch on the Bios again and it did work), but I still don't have hardware acceleration.
I have added the 3 kexts and done the config changes and checked them about 3 times - the second part of XML to be added for dual-processor machines in step 2 is to go inside the </array> tag, not to be added on the end, right?
Am I worth flashing a bios from techpowerup to see if it helps hardware acceleration, is it likely to be bios related?

Yes. Add it just above </array>. Also make sure to double check your device path. It's probably PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0).
You can also use ocvalidate to track down issues with your config. See the "validate" step in the updating procedure in Step 3.
Unlikely.
Thanks, that's what I've done, above the </array>, and that was my path as well which I had changed.
I've tried OC validate and it says no issues.
The weird thing is my graphics card isn't showing in VideoProc which I think is what is used in the original post to check hardware acceleration - but it does show in system report - is there another way to reliably check hardware acceleration?

VideoProc also shows 10.16 not Big Sur - is this a compatibility issue?
I've been playing with Final Cut Pro on this Mac, and in Activity Monitor I am having a lot of GPU activity on the encode / decode services that I didn't have yesterday - an performance seems to be improved - so I'm wondering if I've got this wrong and it's working but Videoproc isn't reporting properly.

This is a known issue with VideoProc. You can also use VDADecoderChecker.
I believe this is normal.
Perhaps Lilu and WhateverGreen are not loaded. You can check by entering
kextstat in terminal.To rule out an issue with your OpenCore setup you can always try Martin's package. It should have everything already setup for hardware acceleration. However, for a clean and sustainable use of OC, I recommend that once your testing is done, you get your own configuration working, as outlined here in the guide.
I think I am working now. I'm sorry for wasting your time but I think I hadn't actually noticed that the VideoProc status has a refresh button next to it. I was logged on as a different user and I opened it and it showed Available, back in as my Admin user it shows red as the screenshot above, but click the Refresh button and it's green. I must have fixed it since loading VideoProc the first time - I assumed it ran these tests on each load.
kextstat shows the packages and VDADecoderChecker confirms working.
The only thing I had changed was putting the VMM flag back on, which I don't know if is needed for hybridisation, but I had it off initially as I'd done the install a couple days ago.

Only board ID is iMac Pro. Everything else is Mac Pro, so macOS should report your machine as it always has.
Does anyone notice that Excel and certain apps are choppy and stutter when using? If I have a big spreadsheet open it's really bad. Some websites do the same, especially those with a lot of graphic content.
This is happening with OC in Catalina and BS. Mojave may have still had an issue but I can't remember with certainty.

Check out this post - you will need to store your own BIOS into the flash folder after creating the USB stick on your Mac. The distribution does not contain any desktop card BIOS versions.
These days I have had to replace my GPU (XFX Radeon RX580) because of a hardware problem. BTW Service exchanged me for a new one after 11 month of my bought (even although its price is now 400% higher).
My New GPU is exactly the same model. My OpenCore config didn't change but I have now a very strange bootpicker in green and very low resolution. After Booting everything works fine in BigSur, Mojave (Hardware Accel included) and Windows 10.
I have checked again my config.plst, Opencanopy. PickerVariant (is in "modern") and EFI folder (Resources, Ketxt etc) following the guide in #1.
I have tried with both firmwares (using left and right option in the tiny switch of the GPU)
Maybe my issue is already treated before but I can not find it. Thanks
EDIT: JANUARY/01/2022: I fixed the problem updating my GPU BIOS in windows. I just could do it using an old version of ATIFLASH (2.9.3) and a Flashing procedure via cmd. With modern versions of ATI FLASH it was impossible.

Okay so I wanted to install macOS Big Sur 11.3 RC from a fresh reinstall of macOS Big Sur 11.2.3 and OpenCore 0.6.8 (VMM was off). However, my cMP has now "hung up" and won‘t start anymore. In OpenCanopy it never showed me that the update was even being installed. I have already reseted the NVRAM, however this did not solve my problem. Does anyone have the same problem or know how I can solve this? Thanks in advance.
I had an issue with my boot picker looking weird and I fixed it by changing to another HDMI cable.
Sorry I forgot to add a picture. It almost always gets stuck there, sometimes my Mac would "exit" verbose mode but still hang. I hope this is understandable.
Does not look good. Can you not reinstall it from the recovery partition (press space bar at the OpenCanopy)
Thank you rx78. I will try HDMI cables but I use two 4k monitors using DisplayPort cables. Three OS start and work perfectly in 4k after Opencore booting
I'll give it a try, but that's weird isn't it? By the way, I have the same problem even if I try it with another SSD that also has a fresh install of macOS Big Sur 11.2.3. The problem has been with me since the early beta versions of 11.3. So far I have never been able to get macOS Big Sur 11.3 to run on my cMP even with OpenCore 0.6.7 not. Do you have macOS Big Sur 11.3 running?

Doesn't look good to me at all that happens when I boot into recovery from 11.3! I don't even know what that means. Looks like I have to reinstall macOS Big Sur 11.2.3, dammit! I'll try to install macOS Big Sur 11.4 Beta.

Hello folks I need to help.
Currently im running Catalina on SSD on an cMP updated to 5,1 with Opencore
Want to migrate it to BigSur
I disconnected the Catalina SSD.
On a new nvme I installed the latest Opencore and BigSur, install was successfull and everthing is running as expected.
When I plugged the SSD back in, it is chosen as the boot EFI.
Booted back to Catalina but it does not see the nvme BigSur as the Startup Disk.
Any advise how can I make the nvme to be chosen as boot EFI?

After going to 0.6.8, adding the GPU name to the array no longer works as far as VideoProc displaying GPU name. It's cosmetic though but I am curious as to why it worked in 0.6.7 but not 0.6.8.
Only one OC per computer. You have two (on the Big Sur and on the Catalina disks).
Remove OC from either disk, bless it properly.
bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/BOOT/BOOTx64.efi --verbose.Where /Volumes/EFI is your actual boot EFI partition.
Select Big Sur from the OC boot picker and once booted set as default boot in System Preferences.
Okay, this is getting really weird!
Today I created two partitions on one HDD, both with a new installation of macOS Big Sur 11.2.3 via OpenCore 0.6.8.
I was then able to successfully update one partition to macOS Big Sur 11.4 Beta 1 via the Developer Seed. However, I could not update the other partition via the Public Seed to macOS Big Sur 11.3 RC. My Mac downloaded the macOS Big Sur 11.3 update normally, but then it didn't even start the installation, instead it was directly shown the crossed out error logo. NVRAM and SMC resets did not help again.
Again my question, has anyone successfully run macOS Big Sur 11.3 RC as a fresh install?
Regards,
Tobias
