# Building and installing OpenCore

Now that we have a macOS installer, lets now build our OpenCore configuration!

First Download the latest release:

Next, run the OpenCore-Patcher.app:

From here you have a couple important options:

  • Build OpenCore
  • Install OpenCore to USB/internal drive
  • Change Model
  • Patcher Settings

If you're patching for a different machine than you're running, please select "Change Model" and enter the updated SMBIOS. For more advanced users, you may also tweak the patcher's build settings via "Patcher Settings"

Now lets enter "Build OpenCore":

The process should be quite quick to build, once finished you'll be plopped back to the main menu.

Next lets run Install OpenCore to USB/internal drive:

Select Drive Select EFI/FAT32 Partition
  • If you have issues, please ensure you install OpenCore onto a FAT32 partition to ensure your Mac is able to boot it. You will need to format your drive as GUID/GPT in Disk Utility

# How to debug with OpenCore

For those who've hit an odd bug and unsure if it's user error or patcher, the below will tell you how to get more verbose debug information as well as logs to help file issues with us (opens new window)

# Debugging yourself

The easiest way to debug yourself is via Patcher Settings. Here there are many different settings however the 3 main options that will help are:

  • "Enable Verbose Mode"
  • "Enable OpenCore DEBUG"
  • "Enable Kext DEBUG"

When you've enabled these 3 options, rebuild OpenCore and install to your drive. This will provide much greater debug information as well as write logs to the EFI Partition.

# Obtaining OpenCore logs from disk

With "Enable OpenCore DEBUG" set, every boot there will be a .txt file generated in your disk. To grab these logs, download and run MountEFI (opens new window):

Once you've mounted the EFI Partition of the drive you have macOS on, you should see some nice logs:

# Obtaining Kernel logs from macOS

With "Enable Kext DEBUG" set, every boot will now have much more detailed logs stored in the OS. To get these logs, simply run the below command:

sudo dmesg > ~/Desktop/DMESG.txt

  • Target OS (ie. macOS 11.2.3)
    •  
  • Host OS (ie. macOS 10.15.7)

  • Upload of your OpenCore Build Folder
    •  
  • Upload of your OpenCore log (if applicable)
    •  
  • Upload of your Kernel log (if applicable)
 
Additionally, please search whether the issue has been reported before. This avoids having duplicate issues.

# Supporting the patcher

OpenCore Legacy Patcher is a hobby project for us developers, and while we love helping out the community it's very difficult for us to troubleshoot issues remotely. The best way for us to get to work on the patcher, fix issues and add enhancements is having the hardware in-hand. As a hobby project, neither of the main developers can afford to buy every legacy Mac to test on.

The best way to support us in all honesty is to donate any old hardware you no longer need, as this allows us to have machines to test locally and push fixes much faster. While we appreciate cash donations, this makes it much more difficult for us to handle as an organization.

Main hardware we'd appreciate:

# Downloading

The simplest way to download macOS installs would be to use installinstallmacos:

mkdir ~/macOS-installer && cd ~/macOS-installer && curl -O https://raw.githubusercontent.com/munki/macadmin-scripts/main/installinstallmacos.py && sudo python installinstallmacos.py
 
 
As you can see, we get a nice list of macOS installers. If you need a particular versions of macOS, you can select it by typing the number next to it. For this example we'll choose 10:
 
 
This is going to take a while as we're downloading the entire 12GB+ macOS installer.
 
Once finished, you'll find in your ~/macOS-Installer/ folder a DMG containing the macOS Installer, called Install_macOS_11.1-20C69.dmg for example. Mount it and you'll find the installer application.
 
  • Note: We recommend to move the Install macOS.app into the /Applications folder, as we'll be executing commands from there.
    •  
  • Note 2: Running Cmd+Shift+G in Finder will allow you to easily jump to ~/macOS-installer
 
 
 
# Building
 
Now we'll be formatting the USB to prep for both the macOS installer and OpenCore. We'll want to use macOS Extended (HFS+) with a GUID partition map(Using GUID is important for the patcher). This will create two partitions: the main MyVolume and a second called EFI which is used as a boot partition where your Mac's firmware will check for boot files. EFI partitions will be hidden by default, so don't worry if you don't immediately see them.
 
  • Note: By default, Disk Utility only shows partitions – press Cmd/Win+2 to show all devices (alternatively you can press the View button)
 
Formatting the USB
 
Next run the createinstallmedia command provided by Apple (opens new window). Note that the command is made for USB's formatted with the name MyVolume:
 
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
 
  • Note: You can also replace the createinstallmedia path with that of where your installer's located (same idea with the drive name).

# Post-Installation

# Booting without USB drive

Once you've installed macOS through OpenCore, you can boot up and go through the regular install process. To boot without the USB drive plugged in is quite simple:

  • Download OpenCore Legacy Patcher
  • Change Patcher settings as you'd like
  • Build OpenCore again
  • Install OpenCore to internal drive
  • Reboot holding Option, and select the internal EFI

And voila! No more USB drive required

# Booting seamlessly without Verbose or OpenCore Picker

To do this, run the OpenCore Patcher and head to Patcher Settings:

Here you can change different patcher settings, however the main interest is:

  • Set ShowPicker Mode

Once you've toggled them both off, build your OpenCore EFI once again and install to your desired drive. Now to show the OpenCore selector, you can simply hold down the "ESC" key while clicking on EFI boot, then you can release the "ESC" key when you see the cursor arrow at the top left.

Note: For users who need Post-Install Volume patches for Audio support, you must disable the following settings in "Patcher Settings" when building and installing your new OpenCore:

  • SIP: Disabled
  • SecureBootModel: Disabled

Once set, rebuild OpenCore, install to drive and reboot. Then, Post-Install Volume patches will run just fine

# What is OpenCore?

This is a sophisticated boot loader used to inject and patch data in memory, instead of on disk. This means we're able to get near-native experience on many unsupported Macs with Metal GPUs. This includes many of the long desired features of other patchers such as:

  • System Integrity Protection, FileVault 2, .im4m Secure Boot and Vaulting
  • Native OTA OS DELTA updates on all Macs
  • Recovery OS, Safe Mode and Single-user Mode booting

While many PC users from the Hackintosh community are familiar with OpenCore, OpenCore was designed as Mac and PC agnostic ensuring both platforms can use it easily. And with OpenCore Legacy Patcher, we help automate the process making running with OpenCore that much easier.

For advanced troubleshooting, we highly recommend users check out the Unsupported Mac Discord Server (opens new window) as this is generally the quickest way to get a hold of us developers and get help from the community.

For those who wish to support this patcher, please see the Supporting the Patcher page

# How do I get started?

  1. The first step of ensuring whether your model is support is checking here:
  1. Download and build macOS Installer
  2. Run the OpenCore-Patcher.app
  3. Reboot and boot OpenCore

While many PC users from the Hackintosh community are familiar with OpenCore, OpenCore was designed as Mac and PC agnostic ensuring both platforms can use it easily. And with OpenCore Legacy Patcher, we help automate the process making running with OpenCore that much easier.

For advanced troubleshooting, we highly recommend users check out the Unsupported Mac Discord Server (opens new window) as this is generally the quickest way to get a hold of us developers and get help from the community.

For those who wish to support this patcher, please see the Supporting the Patcher page

# How do I get started?

  1. The first step of ensuring whether your model is support is checking here:
  1. Download and build macOS Installer
  2. Run the OpenCore-Patcher.app
  3. Reboot and boot OpenCore

# OpenCore Patcher Terminology

With OpenCore Legacy Patcher, we use a lot of different terms to refer to hardware including SSE4.1, 32-Bit Firmware, etc. This page is to help users understand what all these confusing words mean.

# Terminology

Term Description
macOS Apple's own UNIX based OS used for Mac machines and "What makes a Mac a Mac".
Windows Microsoft's proprietary OS that is used and supported on a wide range of devices (stay with this OS if you don't want headaches)
Linux Family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged in a Linux distribution. Note that while macOS and Linux may be UNIX-based, they're vastly different.
Bootloader Piece of software that loads an OS, usually made by the OS creators. OpenCore is technically not a bootloader per se (see boot manager explanation down below). Apple's Boot.efi would be the actual boot loader in a Mac.
Boot Manager Piece of software that manages bootloaders – we have many of these: Clover, systemd-boot, OpenCore, rEFInd, rEFIt... These are generally seen as prepping the system for the actual boot loader.
Term Description
OpenCore The new hotness on the scene, made with security in mind by the Acidanthera team (opens new window), has faster booting and lighter weight than previous boot managers. Supports many native Mac features such as SIP, FileVault, Secure Boot, etc
ACPI Tables defined in your firmware defining your hardware and different methods, tied directly to how IOKit/IOService handles device setup
NVRAM Non-volitile storage, where many variables are stored including default boot options, Hibernation keys, Secure Boot information, etc
Term Description
XNU Also known as X is Not Unix, XNU is referred to as macOS's "kernel" and the heart of what makes macOS tick
Kexts Also known as Kernel Extensions, are macOS's drivers. They're used to perform different tasks like device drivers or for a different purpose (in this patcher) like patching the OS, injecting information or running tasks.
KernelCollection Also known as the ImmutableKernel and PrelinkedKernel, this is a bundle of the kernel(XNU) and kernel extensions(Kexts) that we use to boot macOS. This is also what OpenCore patches in memory to allow us to have a seamless experience
- PrelinkedKernel: Default caching system since 10.7
- ImmutableKernel: Secure Boot based caching system since 10.13
- KernelCollection: Merge of both Prelinked and ImmutableKernel's since macOS 11, Big Sur
IOKit Backbone of how Kernel Extentions (Kexts) probe and attach onto hardware, starts quickly after kernel initates
WindowServer Backbone of the GUI interface in macOS, one of the first userfacing userspace programs to kick-in
OTA Short for Over The Air, refers to native OS updates via System Preferences like a supported Mac
DELTA Often used with OTA, refers to OS updates that much smaller than full installers (generally ~3GB), note Deltas require the root volume to be unmotified otherwise ~12GB updates will occur.
Term Description
EFI It can denote two things:
- Mac's firmware, which is the same as UEFI, but pretty modified for Macs only, so not so "Universal"
- The partition on your hard drive that stores software read by the UEFI to load OSes (like the Windows bootloader) or UEFI Applications (like OpenCore), it's FAT32 formatted and has an ID type of EF00 (in hex). It can be named ESP or SYSTEM, and it's usually from 100MB to 400MB in size but the size doesn't reflect upon anything.
HFS+ Also known as MacOS Journaled, this was the default macOS drive format up until macOS 10.13, format was designed around spinning disks
APFS This was the default macOS drive from macOS 10.13 and onwards for SSDs, and standard for all drives in Mojave. Format was designed around SSDs primarily.
32 and 64-Bit CPU The bit number of a CPU determines how much data a CPU can address.
- 32-Bit CPUs were only supported up-to Mac OS X 10.6, Snow Leopard.
32-Bit Firmware The bit number of a Firmware determines how much data the firmware can address. In some older Macs, it's common to have a 64-Bit CPU can have a 32-Bit firmware
- 32-Bit Firmwares were only supported up-to Mac OS X 10.7, Lion.
SSE Instructions Also known as SIMD Single-Precision Floating-Point Instructions, these are defined as instruction sets supported by your CPU. In macOS, there are a certain number of instruction sets required for normal operation:
- SSE3: Required for all Intel CPUs since Mac OS X 10.4, Tiger
- SSSE3: Required for all Intel 64-Bit CPUs since Mac OS X 10.6, Snow Leopard
- SSE4.1: Required for all Intel CPUs since macOS 10.12, Sierra

# Troubleshooting

Here are some common errors users may experience while using this patcher:

# Stuck on This version of Mac OS X is not supported on this platform

This means macOS has detected a SMBIOS it does not support, to resolve this ensure you're booting OpenCore before the macOS installer in the boot picker. Reminder the option will be called EFI Boot

Once you've booted OpenCore at least once, your hardware should now auto boot it until either NVRAM reset or you remove the drive with OpenCore installed.

# Cannot boot macOS without the USB

By default, the OpenCore Patcher won't install OpenCore onto the internal drive itself during installs. Instead, you'll need to either manually transfer (opens new window) OpenCore to the internal drive's EFI or run this patcher's Option 2 again but select your internal drive.

Reminder that once this is done, you'll need to select OpenCore in the boot picker again for your hardware to remember this entry and auto boot from then on.

# Infinite Recovery OS Booting

With OpenCore Legacy Patcher, we rely on Apple Secure Boot to ensure OS updates work correctly and reliably with Big Sur. However this installs NVRAM variables that will confuse your Mac if not running with OpenCore. To resolve, simply uninstall OpenCore and reset NVRAM (opens new window).

  • Note: Machines with modded root volumes will also result in infinite recovery until integrity is restored

# Reboot when entering Hibernation (Sleep Wake Failure)

Known issue on some models (opens new window), temporary fix is to disable Hibernation:

sudo pmset -a hibernatemode 0

sudo pmset -a hibernatemode 0
 
# Booting with a non-flashed GPU
 
For Mac Pro, Xserve and iMac users with non-flashed GPUs, you can still easily boot OpenCore and view the entire boot process. To do so, make sure SIP is disabled(to allow NVRAM write access) and run the following:
 
sudo bless --verbose --file /Volumes/VOLNAME/EFI/OC/OpenCore.efi --folder /Volumes/VOLNAME/EFI/OC --setBoot
 
  • Note you will need to replace VOLNAME with the Volume name of your USB or hard drive with OpenCore
    •  
  • Note 2: Once done, you can re-enable SIP
 
Once you boot OpenCore for the first time, LauncherOption will install itself as the top boot priority making OpenCore always launch. Combined with RequestBootVar, all boot options must go through OpenCore ensuring seamless usage even with OS installation and updates.
 
# How to Boot Big Sur Recovery
 
By default, the patcher will try to hide extra boot options such as recovery from the user. To make them appear, simply press the "Spacebar" inside OpenCore's Picker to list all boot options.
 
# Stuck on "Your Mac needs a firmware update"
 
Full error: "Your Mac needs a firmware update in order to install to this Volume. Please select a Mac OS Extended (Journaled) volume instead."
 
This error occurs when macOS determines the firmware to not have full APFS support. To resolve is quite simple, when building OpenCore head to "Patcher Settings" and enable "Moderate SMBIOS Patching" or higher. This will ensure that the firmware reported will show as supporting full APFS capabilities.

To remove OpenCore is actually quite simply:

  1. Remove OpenCore either from the USB or internal drive
  1. Reset NVRAM

Know that if you are on Big Sur when you remove the EFI folder, your Mac will no longer boot and show the prohibited symbol. Be ready to install an older version of macOS before you uninstall OpenCore.

# Updating OpenCore and Co.

With OpenCore Legacy Patcher, generally there's very little reason for users to update the OpenCore installed on their machine unless you feel there's a benefit with new versions for your setup.

For those who do wish to update, it's actually quite easy. Simply download the latest release (opens new window) and rerun the patcher:

Then simply rebuild your OpenCore build and install again. Then voila, OpenCore is updated!

To check what version of OpenCore and Patcher version you're currently running, you can run the following in terminal:

For those who do wish to update, it's actually quite easy. Simply download the latest release (opens new window) and rerun the patcher:
 
 
Then simply rebuild your OpenCore build and install again. Then voila, OpenCore is updated!
 
To check what version of OpenCore and Patcher version you're currently running, you can run the following in terminal:
 
# OpenCore Version
 nvram 4D1FDA02-38C7-4A6A-9CC6-4BCCA8B30102:opencore-version

OpenCore Legacy Patcher

Experience macOS just like before @@ -28,6 +28,6 @@

Built with security in mind

Supporting System Integrity Protection(SIP), FileVault 2, .im4m Secure Boot and Vaulting. You're just as secure as a supported Mac

Native OTA updates

Install updates the moment they come out just like on a supported Mac, and no more 12GB+ updates.

Zero firmware patching

No need to patch APFS ROM support, all protocol upgrades are done in memory and never permanent.
