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

cdf · Oct 27, 2019

In this guide, you'll learn how to use OpenCore to install, run and update macOS Catalina, Big Sur and Monterey on the 2009–2012 Mac Pro, ending up with a clean unaltered operating system just like on a supported Mac.

The approach described in this guide is for setting up and configuring OpenCore manually in a manner that aims to promote an understanding of the resulting configuration. There are other ways of setting up and configuring OpenCore on the Mac Pro that were developed after the approach described in this guide and that draw on this guide to varying extents. A popular example is OCLP (OpenCore Legacy Patcher), which sets up and configures OpenCore automatically on the Mac Pro as well as on a wide range of other legacy Macs. For support with OCLP, please use their recommended support channel.

Introduction

OpenCore is an advanced boot loader program that expands the hardware compatibility of macOS by injecting key data into memory. In addition to keeping macOS more up to date (and therefore more secure), there are two major advantages to using OpenCore on the 2009–2012 Mac Pro:

boot-screen support (even with a standard graphics card)

hardware acceleration (with DRM support for streaming on Safari)

This guide

This guide offers a purist's approach:

it provides a minimal setup that puts you in control (learn about OpenCore's settings without any layers of abstraction)

it promotes usage practices intended by Apple (SIP, Secure Boot, clean NVRAM, vanilla features)

While this guide can be used to set OpenCore up on a wide variety of legacy Macs, it is specifically aimed at the following systems:

Hardware ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Requirement ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Mac Pro model Early 2009 with MacPro5,1 firmware, Mid 2010, or Mid 2012
Processor architecture Westmere (E56xx, L56xx, and X56xx) or Gulftown (W36xx)
Firmware version 144.0.0.0.0 (need to update?)
Graphics Supported GPU (such as RX 580, Radeon VII, and 5700 XT)
Wireless Supported modules (such as BCM94360CD and BCM943602CDP)

Other approaches

Since this guide first appeared, several approaches have been proposed to facilitate the use of OpenCore on the 2009–2012 Mac Pro:

Martin's Package (popular one-size-fits-all solution)

MyBootMgr (RefindPlus chain-loading solution with helper apps)

OC Plistlib Generator (programatic solution compatible with this guide for easily maintaining and updating your OpenCore setup)

OCLP (comprehensive automatic solution for setting up OpenCore based on your hardware)

History

OpenCore can be traced back to a group of anonymous developers known as The Hermit Crabs Labs. The group became well-known for the Ozmosis project, a firmware-based bootloader developed for Quo Computer's Any-Operating-System motherboard. Although Quo enjoyed a successful 2013 Kickstarter campaign, the company no longer exists.

In the mid-to-late 2010s, Acidanthera, a group of developers led by @vit9696 and mhaeuser, revisited the project. After a complete rewrite, they released the first version of OpenCore in mid 2019.

Shortly after this release, Catalina Loader, a partial OpenCore solution for legacy Apple hardware, was proposed by @Rastafabi. Somewhat of a curiosity at this stage, the solution was only for tricking the macOS installer, not for actually running macOS.

In late 2019, the first OpenCore solution for installing, running and updating macOS on Apple hardware was presented here in this guide. This solution received a lot of attention from the Mac Pro community and led to finally activating AMD hardware acceleration. Even Acidanthera took notice and stepped in to solve the most enduring problem with the classic Mac Pro: the lack of preboot graphics with standard graphics cards.

It took over a year and the release of OCLP for the larger unsupported-Mac community to finally embrace OpenCore. During that time the Mac Pro community continued refining its use of OpenCore, developing key configuration strategies, which would eventually be adopted for legacy Macs of all kinds.

Basic setup

This part of the guide provides step-by-step instructions for installing OpenCore on your Mac.

Boot natively

✓ The first step is to boot into macOS natively (no patched installs, no third-party boot loaders).

On MacPro5,1, the last natively bootable version of macOS is Mojave.

⚠️ It is important to always have a disk with a natively bootable installation of macOS. That way, you can always boot if something goes wrong.

Choose your ESP

Your EFI System Partition (ESP) is the disk volume where you will install OpenCore.

➊ In Terminal, enter the following command:

diskutil list

➋ Look for a volume of type EFI and choose one. Note its identifier. It will be something like "diskAs1".

⚠️ Make sure to look at the names and sizes of the volumes to properly identify the disk where your ESP is located. The identifier you just noted can change from one boot to the next.

A typical choice for your ESP is the EFI volume of the disk on which you plan to install macOS Catalina, Big Sur or Monterey. If your choice corresponds to the current boot disk, make sure that you have another disk with a natively bootable installation of macOS.

➌ Enter the following command, replacing "diskAs1" with the actual identifier of your ESP:

sudo diskutil mount /dev/diskAs1

Your ESP will appear as "EFI" in Finder.

Install the basic components

OpenCore consists of three basic components:

Component ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
OpenCorePkg Main files Download OpenCore-1.0.0-RELEASE.zip
OcBinaryData Graphical user interface files Follow the link, click the code button, then "download ZIP"
config Sample config file for legacy Macs Download from the bottom of this post

➊ Open OpenCorePkg. In the folder "X64", you will see a folder "EFI". Copy this folder to your ESP.

It is possible that your ESP already contains a folder "EFI" (Macs use EFI partitions as a staging area for firmware updates). In this case, you can safely delete the existing folder before.

➋ In the folder "EFI" (now on your ESP), you will see a folder "OC". Copy the file "config.plist" to this folder.

This file is your config. It is the most important part of your setup.

➌ Open OcBinaryData. Copy the folder "Resources" to the folder "OC", overwriting the existing folder of the same name.

➍ Verify that your ESP contains the following files and folders:

ESP ("EFI" in Finder)
└── EFI
⠀⠀ ⠀├── BOOT
⠀⠀ ⠀│⠀ ⠀└── BOOTx64.efi
⠀⠀ ⠀└── OC
⠀⠀⠀⠀ ⠀ ⠀├── ACPI
⠀⠀⠀⠀ ⠀ ⠀├── config.plist
⠀⠀⠀⠀ ⠀ ⠀├── Drivers
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀├── OpenCanopy.efi
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀└── OpenRuntime.efi
⠀⠀⠀⠀ ⠀ ⠀├── Kexts
⠀⠀⠀⠀ ⠀ ⠀├── OpenCore.efi
⠀⠀⠀⠀ ⠀ ⠀├── Resources
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀├── Audio
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀├── Font (4 files, see below)
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀├── Image
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀│⠀ ⠀└── Acidanthera
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀│⠀⠀⠀ ⠀ ⠀└── GoldenGate (23 files)
⠀⠀⠀⠀ ⠀ ⠀│⠀ ⠀└── Label (23 files)
⠀⠀⠀⠀ ⠀ ⠀└── Tools

To keep things nice and tidy, the following files and folders can be deleted:

the files "Terminus.hex" and "TerminusCore.hex" in the folder "Fonts"

all files in the folders "Audio" and "Tools"

all files in the folder "Drivers", except for the files "OpenCanopy.efi" and "OpenRuntime.efi"

all folders in the folder "Acidanthera", except for the folder "GoldenGate"

🎉 Congratulations! You now have a basic OpenCore setup and are ready for the first boot.

First boot

If your Mac has native boot-screen support

➊ Reboot and hold Option to enter Startup Manager.
➋ Use the arrow keys to select "EFI Boot", then holding Control, press Enter.

OpenCore will start and is selected for booting automatically.

If your Mac lacks native boot screen support

➊ Reboot and hold Command-R to enter Recovery. You can also use the following command:

sudo nvram "recovery-boot-mode=unused" && sudo reboot recovery

⚠️ Be patient. Without boot screen support, it may take a while before something appears on your screen.

➋ In Terminal (Menu bar > Utilities > Terminal), enter the following command:

diskutil list

➌ Look for your ESP, noting its identifier. It will be something like diskAs1.

➍ Enter the following command, replacing "diskAs1" with the actual identifier of your ESP:

diskutil mount /dev/diskAs1

➎ Enter the following command:

bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/EFI/BOOT/BOOTx64.efi

➏ Reboot.

OpenCore will start and is selected for booting automatically.

Confirm your installation

Your Mac should now be booted into macOS through OpenCore.

✓ In the Terminal app, enter the following command:

nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version

You should see the current version of OpenCore. With OpenCore successfully installed, it is time to take a closer look at the settings.

Mount your ESP

➊ In Terminal, enter the following command:

diskutil list

Look for your ESP, noting its identifier. It will be something like "diskAs1".

➋ Enter the following command, replacing "diskAs1" with the actual identifier of your ESP:

sudo diskutil mount /dev/diskAs1

Your ESP will appear as "EFI" in Finder.

Open a copy of your config in your home folder

➊ Copy your config to your home folder (this is the folder with your user name in macOS).

➋ Using TextEdit, open the copy of your config in your home folder.

Overview of basic settings

The sample config provided in this guide is optimized for minimality, offering a baseline for any Mac. Most options are disabled or set to the OpenCore failsafe values. There are only a few carefully chosen exceptions, which are described below.

Setting ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Value ⠀ ⠀
Explanation ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
DisableLinkeditJettison true Required for reliable use of the Lilu kernel extension
ProtectSecureBoot true Protect against BootROM damage from UEFI Windows
SetApfsTrimTimeout 0 Disable Trim for APFS
PickerAttributes 16 Allow pointer control in boot menu
PickerMode External Use graphical user interface for boot menu
PickerVariant Default Use modern black-and-white theme
PollAppleHotKeys true Allow Mac startup key combinations
ShowPicker true Show the boot menu automatically at startup
Timeout 10 Automatically boot the default selection after 10 seconds
AllowSetDefault true Allow using Control-Enter to set the default selection in boot menu
BlacklistAppleUpdate true Prevent unwanted firmware updates
Vault Optional No integrity checking of OpenCore
SecureBootModel Disabled Disable Startup Security
TimerResolution 100000 Use Mac value (10 milliseconds)
DirectGopRendering true Use special video renderer
ProvideConsoleGop true Enable preboot video output
UIScale 0 Automatically scale boot menu based on current resolution
AppleBootPolicy true Help load Recovery
AppleUserInterfaceTheme true Allow modern black-and-white theme
RequestBootVarRouting true Allow boot management for seamless OS installations and updates

You may want to make a few changes. Here are a few possibilities that are compatible with this guide:

Setting ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Value ⠀ ⠀
Explanation ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
ForceBooterSignature true true is required for Hibernation
SetApfsTrimTimeout 9999999 Use Mac value (9.999999 seconds) unless boot times become too long (experiment)
ThirdPartyDrives true true is recommended to enable trim on standard SSD drives
HibernateSkipsPicker true Hide the boot menu when waking from hibernation
HideAuxiliary true Hide Recovery (press Space at the boot menu to reveal)
LauncherOption Full Full is recommended to ensure boot persistence of OpenCore
DirectGopRendering false false is recommended as long as the boot menu still appears (experiment)
GopBurstMode true true is recommended to accelerate preboot video but it can break booting (experiment)
ProvideConsoleGop false false is recommended only if your Mac has native boot screen support (see Appendix)
PickerAttributes 80 Enable pointer control and hide shutdown and restart buttons
ShowPicker false Hide the boot menu (hold Escape at startup to show)
Timeout 0 Disable timeout when boot menu is shown
ExposeSensitiveData 0 Minimize traces of OpenCore
SecureBootModel Default Default is recommended for security once you have updated to macOS Big Sur or later
WriteFlash true true is only recommended if your firmware chip is healthy (need to check?)
AppleBootPolicy false false is recommended once you have updated to macOS Catalina or later

Making changes to these settings is easy. For example, here's how to set LauncherOption to Full:

Find ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Replace ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
<key>Misc</Key>

<string>Disabled</string> <key>Misc</Key>
<dict>
⋮
<key>Boot</Key>
<dict>
⋮
<key>LauncherOption</key>
<string>Full</string>

With LauncherOption set to Full, OpenCore is guaranteed to boot on the next boot after booting just once. This is especially useful if your ESP is on the disk with the top boot priority after an NVRAM reset.

As another example, here's how to set DirectGopRendering to false:

Find ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Replace ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
<key>UEFI</Key>

<true/> <key>UEFI</Key>
<dict>
⋮
<key>Output</Key>
<dict>
⋮
<key>DirectGopRendering</key>
<false/>

DirectGopRendering (which is needed for the Radeon VII and some versions of the 5700 XT but not for the RX 580) can cause undesirable effects (such as slow animations in the OpenCore boot picker) and therefore should be set to false if not needed.

You can always revisit these settings to make more changes later.

Verify your config

➊ Save your changes.
➋ In Terminal, enter the following command:

plutil -convert xml1 config.plist && plutil config.plist

This command will take care of properly formatting your config (so don't worry about the indentation). You should see "config.plist: OK". If not, recheck your edits. Once the check passes, you can proceed to load your config.

Load your config

➊ Copy your config from your home folder back to your ESP as indicated below:

ESP
└── EFI
⠀⠀ ⠀├── BOOT
⠀⠀ ⠀└── OC
⠀⠀⠀⠀ ⠀ ⠀├── ACPI
⠀⠀⠀⠀ ⠀ ⠀├── config.plist
⠀⠀⠀⠀ ⠀ ⠀├── Drivers
⠀⠀⠀⠀ ⠀ ⠀├── Kexts
⠀⠀⠀⠀ ⠀ ⠀├── OpenCore.efi
⠀⠀⠀⠀ ⠀ ⠀├── Resources
⠀⠀⠀⠀ ⠀ ⠀└── Tools

➋ Reboot.

Complete your setup

This part of the guide describes changes that you can make to your basic setup to obtain a more complete and functional setup. Not all changes are necessary. They depend on your particular setup. Make sure to carefully read through all the possibilities to decide. Once you have made the proper changes, you'll be able to install, run, and update macOS Catalina, Big Sur or Monterey on your Mac.

General procedure

➊ Changes to your setup should generally be preceded by the following steps:

Mount your ESP

Open a copy of your config in your home folder

➋ Changes to your setup should generally be followed by the following steps:

Verify your config (especially if the changes to your config are complex)

Load your config

See Basic setup.

Tip: You can make several changes to your setup at once, but if the changes to your config are complex, it's best to verify your config after each change to better identify errors.

Spoofing and enabling missing features

The first step towards completing your setup is to apply a spoofing strategy known as hybridization. Hybridization consists of spoofing the board ID of a supported Mac while keeping other identifiers untouched. This strategy is sufficient for installing macOS and performing over-the-air (OTA) updates while keeping your Mac properly identified in Apple Services (iCloud, Messages, FaceTime). It is also an integral part of enabling hardware acceleration. The recommended board ID is the one from the 2019 Mac Pro (Mac-27AD2F918AE68F61):

gfxutil For getting device paths Download the latest RELEASE version

➌ Copy the executable "gfxutil" to your home folder.
➍ In Terminal, enter the following command:

xattr -c gfxutil

➎ Get the path of your graphics card by entering the following command:

./gfxutil -f display | sed 's|.*= ||'

If your graphics card is in slot 1, the path should be PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0).

➏ Add the device properties, replacing "PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0)" below with the actual path:

Make PCIe drives internal

On the MacPro5,1, macOS sees PCIe drives as external, but it's possible to make them internal. You'll need gfxutil (if you don't already have it from a previous step):

Utility ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
gfxutil For getting device paths Download the latest RELEASE version

➊ Copy the executable "gfxutil" to your home folder.
➋ In Terminal, enter the following command:

xattr -c gfxutil

➌ Get the paths of your drives by entering the following command:

system_profiler SPPCIDataType | grep -B 2 'AHCI Controller\|NVM Express Controller' | grep 'pci' | sed 's|:||' | sort | uniq | xargs -n 1 ./gfxutil -f | sed 's|.*= ||'

Each path should be something like PciRoot(0x0)/Pci(0x0,0x0)/Pci(0x0,0x0).

➍ Add the built-in property for each of your drives. Make sure to use the actual paths.

Repeat the seven lines preceding the last </dict> for each of the paths you noted above. Make sure to use the actual paths.

VMM flag

There are two options for installing and updating macOS in this guide. One option requires enabling the CPUID VMM flag. If you have chosen this option after reading the macOS section below, this is the change you want to make:

⚠️ It is important to enable the VMM flag only when installing and updating. The reason is that the VMM flag impacts performance and disables power management.

Clean up the NVRAM

If you're setting things up for the first time, then you may currently be using OpenCore to boot Mojave or earlier. In this case, the following change does not apply. Come back once you are running Catalina or later.

If you're using OpenCore to boot only Catalina and later, then you can clean up the NVRAM:

Delete ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀

If your configuration depends on other boot arguments, then just delete "-no_compat_check" and leave the rest.

Thunderbolt

One of the most impressive upgrades that can be done to the MacPro5,1 is the addition of Thunderbolt 3 ports. The following instructions describe how to configure your OpenCore setup for a single flashed-for-Mac GC-Titan Ridge card installed in slot 4.

✓ Boot your Mac with your GC-Titan Ridge card (without any previous SSDT loaded for it).

You'll need a few components:

Component ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
MaciASL AML compiler Download the latest release
SSDT-TbtGCTR SSDT file Download from the bottom of this post

➊ Place the "MaciASL" app in your Applications folder.

You can delete this app once you have completed the rest of the steps.

➋ Copy the file "SSDT-TbtGCTR.aml" to your home folder.

This file is your Thunderbolt SSDT, which you will now customize using the brilliant ThunderboltUtil script.

➌ In Terminal, enter the following command:

curl -O -L https://gist.githubusercontent.com/joevt/4f6d4d97b560efab9603ac509bf00122/raw/\
0621ed4d5aa250738dbdb1dad33567928af61624/ThunderboltUtil.sh && source ThunderboltUtil.sh

A script "ThunderboltUtil.sh" will appear in your home folder. You can delete this file once you have completed the rest of the steps.

➍ Now enter the following command:

loadamlfile SSDT-TbtGCTR.aml && usedromnum 1 && setuid `system_profiler SPThunderboltDataType | grep -m 1 'UID: 0x00ED' | sed 's|UID: ||'` && repairchecksums && makedromdsl

A block of text will appear in Terminal.

➎ Copy the block of text (everything from "ThunderboltDROM" to the trailing },).

➏ Open your Thunderbolt SSDT with MaciASL and paste the block of text over the corresponding block (look for "ThunderboltDROM").

Don't worry about the formatting; it will be taken care of automatically.

➐ Press the compile button at the top of the window to confirm that there are no errors and then save the file and close the app.

➑ Move your Thunderbolt SSDT into your ESP as indicated below:

ESP
└── EFI
⠀⠀ ⠀├── BOOT

Maintenance

This part of the guide describes standard maintenance procedures.

Updating OpenCore

Currently, a new version of OpenCore is released on the first Monday of every month.

✓ With the help of the updated sample config at the bottom of this post and the notes below, make any necessary changes to your setup. Hint: Past incremental update notes are available in the WikiPost History.

0.9.9 to 1.0.0

No changes to your config are required for updating from version 0.9.9 to 1.0.0.

Updated components ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
OpenCorePkg

Install the components, as described in Basic setup and Complete your setup (and the Appendix if applicable), overwriting the existing files of the same name. Note that the procedure can be done from an OC-booted system (booting natively is not required).

Validating your config

You'll need a special utility from the main OpenCore files:

Component ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
OpenCorePkg Validation utility Download the latest RELEASE version

➊ Open OpenCorePkg. In the folder "Utilities", you'll see a folder "ocvalidate", in which you'll see an executable "ocvalidate". Copy this executable to your home folder.

➋ In Terminal, enter the following command:

xattr -c ocvalidate

➌ With your config in your home folder, validate your config by entering the following command:

./ocvalidate config.plist

The utility will tell you if your config has been properly updated for the latest version of OpenCore.

Setting up BootKicker

The BootKicker tool allows you to start the native Apple boot picker from OpenCore.

You'll first need to obtain the tool from the main OpenCore files:

Creating a rescue CD

An OpenCore rescue CD makes it possible to boot through OpenCore by holding C at startup.

➊ Create a new folder "OC-CD" in your home folder.
➋ Copy your EFI folder from your ESP to the folder "OC-CD":

OC-CD
└── EFI
⠀⠀ ⠀├── BOOT
⠀⠀ ⠀└── OC

You will need to modify your config in this new instance of OpenCore.

⚠️ Important: Do not try editing your config directly in the new instance of OpenCore. Instead, copy your config out to your home folder as usual, make the change, then copy your config back to the new instance of OpenCore.

➌ Set LauncherOption to Disabled and RequestBootVarRouting to false (for native blessability).

Once the change is made and your modified config is back in place, you can proceed to create the CD.

➍ In Terminal, enter the following command:

hdiutil create -size 200MiB -srcfolder OC-CD -format UDTO -fs FAT32 OC-CD.iso

➎ Insert a blank CD or DVD and enter the following command:

hdiutil burn OC-CD.iso.cdr

To reuse a rewritable disk, use the following command instead:

hdiutil burn -erase OC-CD.iso.cdr

Wait for the task to complete. You will see "Burn completed successfully". You can now go back to your home folder and delete the folder "OC-CD" and the iso file. These files are no longer needed.

⚠️ Important: Because the rescue CD is configured with native blessability it should not be used for installing or updating operating systems.

Booting natively

Via BootKicker

➊ Reboot and select BootKicker at the OpenCore boot menu and press Enter.

You may have to press the Spacebar key to reveal the tool. The tool will start the native Apple boot menu.

➋ Select a natively bootable installation of macOS and press Enter.

Your Mac will automatically restart, and the natively bootable installation of macOS will start without OpenCore.

Debugging

The debug version of OpenCore allows you to generate a log that can help identify issues. You'll need the following component:

Re-enabling OpenCore after disabling it

Via the rescue CD

➊ Reboot and hold C to boot from the rescue CD.
➋ Use the OpenCore boot menu to select "EFI", then holding Control, press Enter.

The screen will black out briefly. On the next boot, OpenCore will start and is selected for booting automatically.

You may see two EFI entries. Selecting either should be fine. If you have more than two EFI entries, then you may need to experiment.

Otherwise

✓ Repeat the first boot procedure. See Basic setup.

macOS

This part of the guide provides information regarding installing and updating macOS with your OpenCore setup.

Clean install or update

If you've followed this guide, then your OpenCore setup allows you to easily install and update macOS up to Monterey. You can do a clean install on an APFS volume or do an OTA update.

Recommended update options:

➊ Clean install with installer app in macOS Mojave and later, or OTA update in macOS Big Sur and later

SecureBootModel is set to Disabled

VMM flag is enabled

➋ Clean install with bootable installer, installer app in macOS Big Sur and later, or OTA update in macOS Big Sur and later

SecureBootModel is set to Default

Hybridization is used

Firmware features are updated

See Basic setup and Complete your setup.

⚠️ Important: Choose one option or the other (not a combination). Option 2 is the vanilla method: it constitutes the settings that you should use anyway when running macOS. However, during installations and updates, option 2 should only be chosen if your firmware chip is healthy (need to check?). If you are uncertain, use option 1.

During the update, your Mac may restart a few times. During these restarts, the default selection on the OpenCore boot menu should be "macOS Installer".

Full installer

To download a full installer of macOS, you can use the excellent installinstallmacos script, which assembles all the necessary files directly from Apple.

⚠️ To use this script in macOS 12.3 or later, you'll need a Python installation.

➊ In Terminal, enter the following command:

curl -O -L https://raw.githubusercontent.com/munki/macadmin-scripts/main/installinstallmacos.py && sudo python installinstallmacos.py

A script "installinstallmacos.py" and a folder "contents" will appear in your home folder. You can delete them once you have the installer.

➋ Choose the desired version of macOS (Catalina, Big Sur or Monterey).

A sparse disk image will be created in your home folder, and this image contains the installer.

Appendix: Windows

This part of the guide provides step-by-step instructions for installing Windows 10 or 11 on your Mac.

Prepare a USB installer

➊ Format a USB flash drive with at least 8 GB of space as ExFAT with the MBR partition scheme. This volume will be referred to as "USB".

You'll need the installer image:

Component ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Windows 10 or 11 Installer image file (ISO) Follow the link, select the edition, then download

➋ Double click the image file. The volume will be referred to here as "CCCOMA_X64".
➌ In Terminal, enter the following command, replacing "USB" and "CCCOMA_X64" with the actual volume names:

rsync -r /Volumes/CCCOMA_X64/ /Volumes/USB

⚠️ Important: Don't forget the "/" after "CCCOMA_X64".

Let the task complete.

Format your Windows disk

✓ Format a disk with at least 32 GB of space as ExFAT with the GUID partition scheme. This volume will be referred to as "Disk C".

Install the ExFat driver

⚠️ If you're using OCLP and have been directed to this guide to install Windows, you can skip this step.

Boot the installer

Before proceeding, make sure that

ProtectSecureBoot is set to true

The VMM flag is disabled

See Basic setup and Complete your setup.

➊ Reboot with the USB installer inserted, and select "Windows" from the OpenCore boot menu.
➋ When the Windows Setup window appears, press Shift-F10 to open Command Prompt.

Identify your disks

➊ In Command Prompt, enter the following command:

diskpart

➋ At the DISKPART prompt, enter the following command

list volume

➌ Look for Disk C and your USB flash drive. You should see something like

Volume 1 ⠀ ⠀ C ⠀ ⠀ Disk C ⠀ ⠀ exFAT
Volume 2 ⠀ ⠀ D ⠀ ⠀ USB ⠀ ⠀ ⠀ exFAT

Note the actual volume numbers and letters.

Reformat your Windows disk

➊ Still at the DISKPART prompt, enter the following command, replacing "Volume 1" by the actual volume number of Disk C:

select volume 1

➋ If you are absolutely sure of the volume number, proceed by entering the following command:

format quick fs=ntfs label=Windows

Wait for the task to complete.

➌ Enter the following command:

exit

Proceed with the installation

➊ In Command Prompt, enter the following command, replacing "D" by the actual volume letter of the USB drive:

D:

➋ Now enter the following commands:

ren efi efi.bak

cd sources

dism /get-wiminfo /wimfile:install.wim

➌ Identify the index of the desired Windows version. You should see something like

Index : 1
Name : Windows 11 Home

➍ Enter the following command, replacing "1" by the actual index of the Windows version and "C" by the actual letter of Disk C:

dism /apply-image /imagefile:install.wim /index:1 /applydir:C:\ /compact /EA

Wait for the task to complete.

➎ Enter the following command, replacing "C" by the actual letter of Disk C and "D" by the actual letter of the USB drive:

bcdboot C:\Windows /s D: /f uefi

Wait for the task to complete.

➏ Finally, enter the following command:

exit

➐ Close the Windows Setup window by clicking the x and reboot into macOS.

Prepare your Windows EFI

➊ In Terminal, enter the following command:

diskutil list

➋ Look for the EFI Partition of Disk C, noting its identifier. It will be something like diskCs1.
➌ Enter the following command, replacing "diskCs1" by the actual identifier:

sudo diskutil mount /dev/diskCs1

The volume should appear as "EFI" in Finder. This is your Windows EFI.

➍ In your Windows EFI, create a folder "EFI".

➎ On the USB drive, in the folder "EFI", you will find a folder "Microsoft". Copy this folder to the folder you just created:

Windows EFI
└── EFI
⠀⠀ ⠀└── Microsoft

➏ On your USB flash drive, delete the folder "EFI" and rename "efi.bak" to "efi".
➐ Eject the drive.

Finish the installation

➊ Reboot and use the OpenCore boot menu to select "Windows".

The configuration process will begin and eventually your Mac will restart.

➋ Follow the guided steps to complete the installation.

Appendix: Native boot screen support

This part of the guide provides instructions for adding EnableGop to your Mac's firmware.

☠️ If performed incorrectly, some the operations in this part of the guide can turn your Mac into a brick! Carefully read through all the instructions first. If you are unsure about something, do not proceed.

Identify your Mac's firmware chip

To complete some of the steps below, you may need to know the part number of your Mac's firmware chip.

Firmware chip location
Part number: SST25VF032B

Possible part numbers include SST25VF032B, MX25L3205D, and MX25L3206E.

Boot natively without SIP

✓ If you are currently booted through OpenCore, follow one of the possible options in Maintenance > Disabling OpenCore.

You'll need to use macOS 10.9 or 10.11 or later. For 10.11 or later, you'll also need to disable SIP:

➊ Reboot and hold Command-R to enter Recovery. The following command in Terminal also works:

sudo nvram "recovery-boot-mode=unused" && sudo reboot recovery

⚠️ Be patient. Without boot screen support, it may take a while before something appears on your screen.

➋ In Terminal (Menu bar > Utilities > Terminal), enter the following command:

csrutil disable

➌ Reboot

Obtain an image of your Mac's firmware

If you have a backup of your Mac's firmware (ideally a reconstructed image)

✓ Simply save the file to your home folder as "Firmware.bin".

If you don't have a backup of your Mac's firmware

You'll need the following utility:

Component ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
Description ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
ROMTool Firmware dumping tool Download ROMTool.zip

⚠️ The password for the zip file is "rom".

✓ Run ROMTool, click "Dump System ROM..." (possibly confirming the part number of your system firmware chip), and save the file to your home folder as "Firmware.bin".

Add EnableGOP

You'll need the following driver and utility:

What to do ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀
OpenCorePkg EnableGop driver Download the latest RELEASE version
DXEInject Driver injection tool Download DXEInject.zip

➊ Open OpenCorePkg and navigate to Utilities/EnableGOP. There, you will find the file "EnableGop.ffs". Copy this file to your home folder.

⚠️ Another possibility is "EnableGopDirect.ffs". Use this file instead if you've determined that your graphics card requires DirectGopRendering in OpenCore (see Basic setup).

➋ Copy the executable "DXEInject" to your home folder.
➌ In Terminal, enter the following command:

xattr -c DXEInject

➍ Add EnableGop to your Mac's firmware image by entering

./DXEInject Firmware.bin GopFirmware.bin EnableGop.ffs

A new file "GopFirmware.bin" will appear in your home folder.

➎ Verify the size of the new file before continuing (Command-click the file and choose "Get Info").

The size should be 4194304 bytes.

Flash the new firmware image

If you don't already have it, you'll need the following utility:

ROMTool Firmware flashing tool Download ROMTool.zip

⚠️ The password for the zip file is "rom".

➊ Shutdown your Mac.

➋ Now enter Firmware Programming Mode by pressing and holding the power button.

After a few seconds of holding the power button, the status indicator light will flash rapidly and you will hear a long tone.

⚠️ Note that certain hardware (some USB 3.0 and SATA PCIe cards) can prevent entering this mode.

➌ Release the power button.

Your Mac will finish booting up.

➍ Run ROMTool, click "Flash System ROM..." (possibly confirming the part number of your Mac's firmware chip), and select "GopFirmware.bin" from your home folder.

With the flashing process complete, you can now delete ROMTool.

➎ Now shutdown your Mac.

The next time you start your Mac, it should have native boot screen support. To re-enable OpenCore, see Basic setup > First boot.

Before I venture down this path, does your OpenCore setup enable boot screens on your "non-bootscreen graphics card"? I'm currently using rEFInd to achieve that, but I'm interested in OpenCore if it can provide the same functionality.

For a 3,1, I would say that the chances are good. OpenCore provides GOP support. However, you will have to edit the configuration file appropriately.

I can confirm the tutorial in post #1 works as expected.

But I haven't figure out how to set iMac Pro SMBIOS yet.

h9826790 · Oct 27, 2019

Just tested update Catalina (to latest beta) via System Preferences -> Software Update natively. Also work perfectly.

w1z · Oct 27, 2019

I can also confirm that OpenCore is working beautifully with Catalina installed on a dedicated NVMe drive, Mojave installed on a shared NVMe drive and with Windows 10 installed in EFI mode on the same shared drive as Mojave.

I did not need to have Mojave installed on a SATA drive.

Now to save those of you wanting to try OpenCore while using Windows 10 in EFI mode from going bananas, the trick to getting Windows EFI to play nicely with OpenCore's Bootx64.efi in /Volumes/EFI/EFI/Boot was to relocate the shared NVMe drive (which has Mojave / Windows 10 installed on it) from slot 3 to slot 2 on the 7101A thus placing it before the dedicated Catalina drive. Reason being, Apple's boot efi is scanning drives backwards / in reverse order with the 7101A ie. NVMe Slots 4 3 2 1 instead of 1 2 3 4 (not sure if this is the case too with other PCIe cards) so now Catalina shows up first in the boot screen.

Also, if you have enabled Apple's full mitigation for disabling hyper-threading, you will need to edit the config.plist file and append cwae=2 to the boot-args string:

Code:

<key>7C436110-AB2A-4BBB-A880-FE41995C9F82</key>
            <dict>
                <key>boot-args</key>
                <string>-no_compat_check cwae=2</string>
            </dict>

I'm loving this! Thanks for sharing @cdf as well as a massive thank you to the developers of OpenCore.

As a record. The following setting to simulate iMac Pro will cause black screen. [Update: fixed by using agdpmod=pikera]

Code:

    <key>PlatformInfo</key>
    <dict>
        <key>Automatic</key>
        <true/>

        <true/>
        <key>UpdateSMBIOSMode</key>
        <string>Create</string>
    </dict>

Basically, UpdateSMBIOS = true will cause black screen.

I haven't have time to insert a Mac EFI UGA GPU or Remote Desktop to check what's happening yet. However, I highly suspect that the cMP actually booted to desktop with the above settings, because the Eject key works, Caps Lock key works, and Command + Control + power button also work.

If the cMP was jammed at loading screen, eject key shouldn't work.

And AFAIK, Command + Control + Power button only react properly inside macOS.

So, very high chance the cMP actually booted to desktop. However, using the iMac Pro SMBIOS cause the GPU fail to display properly.

Anyway, one more good news. PCIe info won't be mess up like using Clover. It's a good start.

Perhaps you could try with UpdateDataHub and UpdateNVRAM set to false. I have been successful with just UpdateSMBIOS set to true with a few model identifiers. I haven't tried iMacPro1,1, though.

Another option is setting the debug properties for creating a log file.

h9826790 · Oct 27, 2019

My setting in post #7 is correct indeed. But it seems after applying the iMac Pro SMBIOS, only the 1st display port on my Radeon VII can display, the other ports are disabled. My cable was connected to the 3rd port, that's why I only got black screen.

Anyway, now I can see the screen, and my cMP ident itself as iMac Pro, and provide Catalina upgrade natively.

h9826790 · Oct 27, 2019

Almost all sensor disappear after applying iMac Pro SMBIOS. But the 2 fans are controllable via iStat. I can spin them up manually.

Now the slightly offtopic question... did this allow you to enable HEVC encode / decode in Catalina (and Mojave hevc encode)?

Clover can wreak havoc on the 5,1's NVRAM. OpenCore was designed for not only hacks but real Macs as well.

The fan control is an essential part of the SMC. If we cannot make them work automatically OC is not safe on the cMP. This is the main reason I did not try unraid server.

CMMChris · Oct 28, 2019

@h9826790 Whatevergreen and agdpmod=pikera (boot arg) should fix your black screen issue and enable all outputs of your graphics card. Alternatively you could also remove the iMacPro1,1 Board ID from the info.plist of AppleGraphicsDevicePolicy.

Regarding the HEVC issues you guys report on the real Mac Pros, try to do an ACPI rename of your GPU from whatever it is called by Apple to GFX0. If this is the root of the problem it should enable HEVC acceleration. On a Hackintosh GFX0 is mandatory for this.

Fan control appears to function fine for my setup. The sensor issue seems to come from spoofing the iMac Pro.

startergo · Oct 28, 2019

Great. Good to know. Have you tried FaceTime and iMessage yet?

cdf · Oct 28, 2019

FaceTime and iMessage seem to work when using OC. However, I've been very careful not to play around with platform information when logged in to these services.

Thanks for pointing me into the right direction. I will study the OpenCore manual and try to config it accordingly.

Hopefully I can fix the following things

1) HEVC hardware encode (both in Mojave and Catalina), if possible, I want to make it available for a 5,1 ident cMP (may be the ACPI rename trick also work for 5,1 ident). This approach may able to avoid unnecessary SMC issue (if I ident the cMP as iMac Pro or 7,1, most sensors disappear).

Apparently, the Radeon VII isn't ident at GFX0 at this moment.

2) In the case of iMac Pro or 7,1 ident, fix the SMC. In my own experience so far. Using iMac Pro SMBIOS makes Handoff etc more reliable. Without 7,1 ident, when I login multiple profiles with multiple Apple ID on my cMP. Handoff often become unstable. But with 7,1 ident, it seems no matter how many profiles I logged in, Handoff still works. But the downside is, all sensors disappear.

I've already try few different VirtualSMC setup, but doesn't change anything yet.

Let's see if I can achieve anything in the next few days.

CMMChris · Oct 29, 2019

Your screenshot doesn't show what the ACPI device is called. You just see the bridges there. Please expand the "IOReg Name" column.

i have this in my Macpro 5.1 whit Radeon vII ... is not GFX..

CMMChris · Oct 29, 2019

Then rename PXS1 to GFX0 and HEVC should start working. It's insane Apple don't take the Mac Pros into account when matching HEVC acceleration to GFX0....

gigignopechegno · Oct 29, 2019

how can you rename in Gfx in a Mac pro?
Can open core do this?
