      OpenCore is required to be able to run newer versions of macOS later than 10.14 Mojave and
      will work for macOS 10.15 Catalina and 11.0 Big Sur

      The is the newest release of OpenCore (0.7.3) which has been updated with the patches
      required for correct functionality on later versions of macOS Big Sur thanks to user Syncretic
      from the MacRumors forums.

      If you have a quad-core or six-core processor please use the EFI from the single socket folder
      and if you have an eight-core or twelve-core model please use the dual-socket EFI.

      These EFI’s will work on Mac Pro 5,1’s or 4,1 models that have been upgraded to a 5,1.

      You will also require a metal-capable graphics card the same as with 10.14 Mojave.
      Here is alist of cards that we know to work but there are more available:
      AMD RX 460, 470 & 480 (10.12.6 SIERRA +)
      AMD RX 560, 570, 580 & 590 (10.12.6 SIERRA +)
      AMD RADEON VII (MOJAVE +)
      AMD VEGA 56, 64 (MOJAVE +)
      AMD RX 5700XT (CATALINA +)
      NVIDIA KEPLAR BASED GPUS (GTX 680, QUADRO K5000, GTX 780, QUADRO NVS 510)
      (just a few examples)

      This version of OpenCore works with macOS 10.15 Catalina and 11.0 Big Sur. If you are using an AMD card it will also work with macOS 12.0 Monterey up to Beta 7. The Nvidia cards are having some issues but we will try to correct this once the final release of Monterey is available. You can also boot into older versions of macOS using OpenCore and as it provides a basic driver for the graphics card you could boot into snow leopard for example with AMD RX 580 but you would not have any acceleration.

      OpenCore adds a boot selector on startup for both AMD and Nvidia (Keplar) based GPUs as
      well as the option to reset the PRAM from this menu which is labeled “Reset NVRAM”.

      If you are using an AMD card based on Polaris or newer (RX 460 or newer) hardware GPU
      acceleration is activated for encoding and decoding both H.264 & H.265 (HEVC).

      Lastly, if you have a modified Titan-Ridge PCIe Thunderbolt card installed in slot 4 this EFI will
      allow for hotplugging devices.

      Is the update on/off folder no longer needed? It is not the zip file

      Thanks

      Hi.

       

      Not at the moment, there is just one EFI version currently which seems to be working well.

      Have you implemented the “SurPlus” fix ?

      Yes, the SurPlus patch has been added.

      Ah awesome thank you so much. I have one other question, will this OC version give me a boot screen with a radeon pro wx5100 ?

      Yes that card should provide a boot screen with opencore. I have not tested it myself but I can’t see why it wouldn’t.

      When you upgrade from opencore 7.2 to 7.3 do you need to re-bless the drive or can you just copy over the files and reboot?

      Also i noticed in my EFI folder that the Apple folder is back. Is that to be expected? ie. in my EFI folder i have Apple, Boot, and OC.

      Thanks

      I installed a Titan Ridge 2.0 card and it works without an issue with OpenCore. However, when I connect a 27″ Thunderbolt display it will not work on boot most of the time (Sometimes it works from boot but most of the time it does not). I have to unplug and plug the monitor from the Titan Ridge card and then it turns on and works every time.  Sometime I get the error “Unplug he accessory using too much power to re-enable USB devices”. This makes me think that the monitor is pulling to much power on boot to work correctly.

      Is there a way to provide extra power to the Titan Ridge card? I have an RX580 graphics card and it is using two 6-pin power connections. Without the monitor turning on at boot I cannot get the brightness control to work because that requires a second USB cable from the monitor be connected. I know this works because 1 in 10 times rebooting it fires up just fine. I have another monitor connected to my graphics card via DVI (dell 30″). I even tried removing a few hard disks but that didn’t help either. I have in my mac the graphics card, Titan Ridge card and 5 drives (two are ssd and one is in the cd drive bay).

      Thanks

      Hi.

       

      Don’t worry about the Apple folder, that’s normal.

       

      You would not have to bless the drive again faster updating the EFI.

      Hi.

       

      I’m assuming you have the displayport passthrough cable attached?

      The display should work every time however the thunderbolt features of the display such as the webcam, speakers, etc will require a restart for functionality as far as I know.

       

      Does your titan-ridge have the custom firmware?

      Hi everyone,
      Due to the recent update of the EFI folder to run Big Sur.
      The steps that you need to take are as follows.
      1. Download fresh EFI from our guide. https://macfinder.co.uk/blog/opencore-catalina-install-guide/
      2. Download open core configurator from this link, there is a small green button here https://mackie100projects.altervista.org/opencore-configurator/
      3. Open the Open core configurator and navigate to the top screen taskbar.
      4. Click Tools, then choose Mount EFI
      5. On the Mount EFI screen in the bottom part EFI partitions, you can find your drive. It will most likely contain information in brackets Data, Preboot, Recovery, VM this is your boot drive.
      6. Press Mount partition put your password in and then click Open Partition.
      7. It will open a separate window for you when you will find your old EFI folder.
      8. Please delete this folder and empty your trash.
      9. Drag/Drop or Copy/Paste the new EFI folder to the EFI partition window.
      10. Go back to the Mount EFI window from the Open Core configurator and click unMount partition to close it, it will close the EFI partition window.
      11. Go to the apple logo left top corner and hit restart.
      12. You are all set to get Big Sur.
      In case of any issues please contact us here OpenCore please do remember this is a part of development that we offer which has been created by great guys, we are trying to reply to all of you but sometimes it takes a little longer. Please describe to us your spec and the step that you do not understand or would like to know more about. In case you are new to Open Core the steps are the same but you skip point 8 and only remove anything that is in this folder(if anything is in there) and continue with this guide. The part you would have to repeat from the original guide is to bless your drive.

      Blessing the drive Open Core.

      When you transferred the EFI folder to the EFI partition through the Open Core configurator, you can find the number of your drive listed like in the picture below. Remember it.

      Screenshot-2021-11-02-at-14.14.54

      1. Power off your Mac Pro.
      2. Make sure you have a wired keyboard plugged in under the power button of your tower.
      3. Hold Command + R on the keyboard and keep holding pressed down.
      4. Tap the power button and keep holding Command + R.
      5. It might take up to 5 minutes when you hold those buttons to boot to recovery.
      6. Once in recovery, navigate to the top taskbar. Choose utilities and select terminal from the drop-down menu.
      7. Once you open the terminal it will have a command line that you do not have to worry about.
      8. Type into terminal diskutil mount /dev/diskAs1 you will replace letter A with the number that you remember from the open core configurator. In my case, it was 0 so the command should look like diskutil mount /dev/disk0s1
      9. Press return and it should say that your EFI partition is mounted.
      10. Next type in bless —mount /Volumes/EFI —setBoot and press return it will return it with bash and field ready to type there will be no confirmation of any sort. Please watch out for this command as — before mount and setBoot is combined from two – signs.
      11. Navigate to the apple logo in the left top corner and select restart.
      12. On this time boot, you should see an EFI loader with drives to select including recovery and NVRAM reset. You can leave it and it will pick your SSD on its own.

      *5. In case you will not see recovery boot after 5 minutes please make sure there is only 1 screen connected to the GPU, that you have manually selected input on the monitor.

      Macpro 5.1 ( mid 2010) RX-580, running Mojave fine for years  on PCI slot SSD. The install for Monterey downloaded from the app store and the  process begins but an error message about  a firmware update cannot be applied quits the process. Any ideas?
