Hi, thanks for the reply. I don't really get it. I used the complete way from this thread (https://forums.macrumors.com/threads/opencore-on-the-mac-pro.2207814/), and HW acceleration dint work. Than I tried the one you suggest in the very first post but you yourself tell to download whatevergreen and to do this argument or am I missing something? Sorry I'm absolutely new to this topic. best regards

Anyway, please just go to post #1314, download the package at there. And follow the video guide in that post to update OpenCore (only do the update, NOT the installation one).

This is pretty awesome!!
Do you have a written guide? Or some screen shots? Bit new to the OC game here.

I just took cdf's default 0.6.3 package, copied the patched Mojave kext to the kext folder of OC (I also removed the Radeon boost and MCEReporter kext as they were unnecessary in a Mac mini), copied the recommended enabling code into the appropriate place in the config.plist (but left it unenabled until I got BS installed). I'm attaching the modded OC EFI folder for your review purposes only. !!! WARNING: THIS EFI & CONFIG IS NO GOOD FOR A 5,1, ONLY APPROPRIATE FOR A LEGACY MINI OR POSSIBLY A LEGACY IMAC !!!

OpenCore 0.5.6 released. I created a new "easy to install package" as per many requested. [The attached package already updated to 0.6.3]

For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in Catalina for dual processor cMP.

I don't mind you guys discuss anything about this package, but I have no plan to provide any explanation about OpenCore at here. If you want to know more, please join cdf's OpenCore thread. For new joiners, please make sure read through the FAQ in post #1 before you ask anything.

The attached packaged included Clover Configurator and a complete preconfigured OpenCore. All credits goes to the developer teams. If you want to show your support, please give them donation (declaration of interest： I am NOT in any of their developer teams)

For Clover Configurator and OpenCore developers teams, please let me know if you want me to remove the associated software inside my attachment in this post.

This is a "one package fit all" solution. So, it's designed to fit as much setup as possible, which may not be optimised for your setup (e.g. I did't provide HiDPI boot screen, for those who are running 4K screen, the Apple logo may be quite small during boot). You have to do the optimisation by yourself (details in the OpenCore manual, some info also available in cdf's OpenCore thread).

Anyway, for those who have RX 460 or newer AMD GPU, this package should gives you:
  1. Boot screen (via GOP for unflashed card, including some Nvidia card)
  2. Firmware protection (to run Windows in EFI mode without risking the cMP bootROM)
  3. HWAccel (H264 / HEVC hardware decode + encode in Mojave or later)
  4. ability to watch DRM streaming content (Mojave and Catalina)
  5. Boot picker (only support EFI systems, tested with Apple wired keyboard, Magic Mouse, and Magic Keyboard, 10s timeout. If you can't see this. Just don't touch the keyboard, and your cMP should continue to boot to desktop)
  6. NVMe and SATA drives on PCIe card show up as internal
  7. Support for Apple USB SuperDrive
  8. TRIM (regardless trimforce status)
  9. Ability to run non-GUI 32bit software in Catalina
  10. Ability to reset NVRAM in boot picker (disabled at this moment to align with the native Apple boot manager)
  11. Ability to run any natively supported ancient OSX with modern graphic card e.g. Radeon VII in 10.6.8 (only can display, no acceleration) [Update 5th May 2020: Sierra and High Sierra may not fully supported yet. Thanks for pierrox's report]
  12. Ability to boot Catalina / Big Sur Recovery Partition
  13. Sleep should work (tested on my cMP, but I can't guarantee it also work with your hardware)
It's impossible for me to test every single function in all situations. So, as usual, use at your own risk. But you are welcome to report back if there is any problem / error.

Pre-installation:
  • Recommend to backup your BootROM between step 1 and 2 (e.g. by using ROMTool)
  • If you want to test OpenCore, you can install this package onto a bootable USB thumb drive.
  • Quite a few users reported that can't boot OpenCore from NVMe, please avoid to install this package on NVMe. You can install this package on ANY SATA drive, not necessary your boot drive.
  • If you want to remove OpenCore, please mount the EFI partition by using Clover Configurator, then remove BOOT and OC folders inside the EFI folder on EFI partition.
  • If your cMP stuck at boot. After shutdown, please pull out the hard drive that contain OpenCore, then perform NVRAM reset. If still doesn't work, then please install your emergency graphic card that has boot screen. Hold Option to boot, then select your backup boot drive. This should disable OpenCore.
  • For those who want to report issue / error. Please provide details (e.g. which graphic card, OpenCore installed on NVMe / SATA drive, the issue's details, etc) otherwise it will be extremely hard (or even impossible) for me to work out what's wrong.
  • If you installed Lilu for whatever reason (e.g. because of innie), or applied my previous non-OpenCore HWAccel mod, please remove them or revert them. For Lilu + WEG, that means delete Lilu.kext in /Library/Extensions/ and reboot (caution: these kexts may be installed in System/Library/Extensions/ as well). For hex edit method, that means delete AppleGVA.framework in /System/Library/PrivateFrameworks/ and rename AppleGVA.framework.bak to AppleGVA.framework. Warning: My package already have Lilu and WEG included, "double installation" of these kexts will cause macOS boot failure.
  • For PULSE RX580, users reported that only can see boot screen when boot from gaming mode. There may be no UEFI GOP in the compute mode's ROM.
Anyway, I tried to make the installation as simple as possible. Here is what you need to do
  1. [Optional] 3x NVRAM reset to avoid some unknown issues.
  2. Disable SIP (must do, especially if you performed step 1)
  3. Download the attachment in this post (Some users reported 0.6.1 package has compatibility issue. You may download the 0.5.9 package if you prefer that, same installation procedures)
  4. Follow the steps in this video
  5. Reboot

For existing OpenCore users, you may follow the step in this video to update OpenCore


Additional option 1: If you have 4K screen, and you want to have "Retina" boot screen. You may do this.

Additional option 2: If you have a flashed Thunderbolt 3 card, you can install that in slot 4, then enable Thunderbolt 3 support by doing this.

Additional option 3: If you want to enable the ability to install / update Catalina [Update: Thanks for cdf's finding. If you are with the 0.6.3 package, and want to install Big Sur, your 5,1 should able to do that "natively". No need to touch the VMM flag etc]

For FCPX users, if you want to export HEVC video by using HWAccel, you will need Compressor.

If you want to completely uninstall my OpenCore package, please follow the steps in this video.

N.B. Unflashed graphic card means "the ROM is never modified". For those who bought used card, and can't see the boot screen, most likely the last user flashed the card with modified ROM (e.g. downvolt for mining). In this case, you can go to TechPowerUp to find a ROM that fit your own card, and flash it.

P.S. If you want to support my work, please donate via the following link. Million thanks in advance! https://www.paypal.com/paypalme/martinlo420

Can't understand the language in that screen capture. But please double check if SIP is disabled, and if you install OpenCore at the correct location
 

h9826790 - Used your 0.6.3 package as is (re-config.plist) on my cMP w/GTX 680mac- Updated Catalina to Big Sur - Perfect! Do you have to have VMM Flag On for subsequent updates of Big Sur?​

 
h9826790 said:
There is a board ID injection to activate HWAccel if you are using my OC package. This may trigger that firmware update issue for some MacOS installer.

You may disable SMBIOS spoofing or even temporarily remove OC for installing Mojave onto your NVMe. (The associated video tutorial in post #1314. The tutorial for enable Catalina installation can also fix that firmware update issue)

But TBH, if you can boot fine with the SATA SSD, why not simply leave the OS at there, and use the NVMe as project drive? There is little to no difference on performance or system responsiveness for most normal daily use anyway.

It seems to have "fixed" itself and seems to be running ok for now. Thanks for the advice though, I'm going to move back to the SATA SSD at some point :)

Hello, I downloaded OpenCore 0.6.3 using the link from @h9826790 on message #1314.

In the idea, I want to install Big Sur + AMD Activation on my Mac Pro.
I read on post # 1314 that it was not recommended to install OpenCore on an Nvme SSD.
I had the idea of installing it on my Nvme SM951 SSD on a PCIe card.

At the moment I find myself with a SATA SSD (Disk A) or I have cloned my Mojave system (it will serve me back if Big Sur does not suit me).
I was planning to erase my Nvme SSD (Disk B) to install Big Sur on it to become my main system if it suits me.

My question is, ect can I install OpenCore on the EFI partition of Disk A (Sata with Mojave) and install BigSur on Disk B (Nvme)? Or should we install OpenCore on the EFI partition of the disk that will receive BigSur?

Thanks for your precisions ;-)

My h9826790 .0.6.3 Package OC is installed on EFI-Nvme SM970 blade on a PCIe Highpoint 7101card. That blade has Big Sur on it and a second SM970 blade has Big Sur on it as well- (2 copies) - Can boot off either blade!! Both updated from Catalina-
h9826790 is the BEST!
**(Have an Nvidia GTX 680 mac GPU so Acell etc. does not work -)

Question: I have a windows 10 legacy install SSD in a bay- I know it doesn’t show in OpenCanopy since it is a Legacy install but I can boot into the legacy install from my (macGTX680GPU) regular Preferences Start-Up Disk- Will I lose (without losing) OC when I boot back to Big Sur?? ​

Any info. would be Greatly Appreciated!! :)​

Since you have GTX680, you can always hold Option to boot, then select EFI to boot to OpenCore.
 
Got Catalina! Woo hoo!! Thank you!

But I have no boot screen :(
Please help.

Spec:
2010 Mac Pro 2x2.66 xeon

Go to TechPowerUp, download the ROM for your card and flash it. 99% can bring the boot screen ability back.

Ive never flashed the rom on this card before, but I looked for the VGA Bios on that website, and my card isn't listed :(
