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).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?
Unlikely.Am I worth flashing a bios from techpowerup to see if it helps hardware acceleration, is it likely to be bios related?
This is a known issue with VideoProc. You can also use VDADecoderChecker.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?
I believe this is normal.VideoProc also shows 10.16 not Big Sur - is this a compatibility issue?
kextstat
in terminal.You can leave VMM off with hybridization.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.Should the machine report as an iMac Pro at any level, in s System Report etc? Or is it only at Bios level and the OS reports as Mac Pro?
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.Thanks, I think I will update the Sierra as it is a nightmare.
For the GPU BIOS flash can I reasonably do in a 5.1 using a Linux live disk or does the card realistically need removing into a windows PC?
I had an issue with my boot picker looking weird and I fixed it by changing to another HDMI cable.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
Screenshot of the hang?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. 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.
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.Screenshot of the hang?
Does not look good. Can you not reinstall it from the recovery partition (press space bar at the OpenCanopy)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.View attachment 1761416
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 bootingI had an issue with my boot picker looking weird and I fixed it by changing to another HDMI cable.
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?Does not look good. Can you not reinstall it from the recovery partition (press space bar at the OpenCanopy)
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.Does not look good. Can you not reinstall it from the recovery partition (press space bar at the OpenCanopy)
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.Thanks, that's what I've done, above the , and that was my path as well which I had changed.
I've tried OC validate and it says no issues.

Only one OC per computer. You have two (on the Big Sur and on the Catalina disks).Any advise how can I make the MVNE to be chosen as boot EFI?
bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/BOOT/BOOTx64.efi --verbose.
