AMD Vanilla OpenCore
Patches for Beta versions are provided but no support is given until the OS is released.
Try these patches at your own risk and always have a backup EFI to boot.
Languages: English (current)
Binary Kernel patches to enable almost native AMD CPU support on macOS.
Read Me First!
Patches are now universal across 15h, 16h, 17h and 19h by utilizing the OpenCore Kenerl Quirk
Make sure to enable this quirk or the system won't boot.
This quirks provides the kernel with the CPU frequencies for macOS to boot
Core Count patch needs modified to boot your system. Find the three
algrey - Force cpuid_cores_per_package patches and alter the
Replace value only.
BA060000 0090* to
B8 <CoreCount> 0000 0000/
BA <CoreCount> 0000 0000/
BA <CoreCount> 0000 0090* substituting
<CoreCount> with the hexideciamal value matching your physical core count.
Note: The three different values reflect the patch for different versions of macOS. Be sure to change all three if you boot macOS 10.13 to macOS 12
See the table below for the values matching your CPU Core Count.
So for example a 6 Core 5600X Replace value would result in these replace values,
B8 06 0000 0000/
BA 06 0000 0000/
BA 06 0000 0090
Note: MacOS Monterey installation requires
Misc -> Security -> SecureBootModel to be disabled in the config.
Also TPM nneds to be disabled in the BIOS. Both can be enabled after install.
Enables macOS to run on AMD CPUs on the fly.
Enables iMessage, Siri, FaceTime, Continuity etc.
Stable compared to custom XNU kernel.
- No 32-bit support (OPEMU) in 10.14 and lower
Supported AMD CPU's
|16h||Jaguar||A Series (including AM4 A-Series)|
|17h and 19h||Zen||Ryzen, 1st, 2nd + 3rd Gen Threadripper, Athlon 2xxGE|
Information on the PAT fix patch
The default enabled patch is Algrey's original patch. This will work for all GPUs and doesn't affect audio but doesn't improve the performance.
The other choice is Shaneee's patch which will increase GPU performance on AMD GPUs but can stop Nvidia GPUs booting. It also causes audio issues when using HDMI and DP audio.
The choice is yours on which patch to use. Please don't try to use them both at the same time.
Note on TRX40 Systems
mtrr_update_action - fix PAT patch has shown an improvement in GPU performance on some systems that have tested. If you wish to test this it is recommended to do so on a USB with OpenCore to ensure it works first. There may be issues with different motherboard/GPU combos that we aren't aware of. Proceed at your own risk.
Supported macOS versions
High Sierra 10.13.x
Big Sur 11.x
Monterey 12.x ( No Support until OS Release )
Download macOS High Sierra, Mojave, Catalina, Big Sur or Monterey from the App Store.
Plug in an empty USB drive.
Run one of the below commands in your Terminal to prepare the bootable macOS USB.
NOTE: Make sure to replace 'MyVolumeName' with your actual USB volume name in the below commands. ## High Sierra sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolumeName ## Mojave sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolumeName ## Catalina sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolumeName ## Big Sur sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolumeName ## Monterey sudo /Applications/Install\ macOS\ Monterey\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolumeName
Install OpenCore on your USB drive. (For OpenCore releases see: https://github.com/acidanthera/OpenCorePkg/releases)
Read the OpenCore Documentaion for
config.plistsetup. A default config will not be provided.
Merge the patches provided into your OpenCore
config.plistand edit it as per your needs.
Use the latest Release of OpenCore to avoid incompatibles. Find the latest release here.
For support creating OpenCore config read the docs and visit this guide or the Discord server.
For 15h_16h CPU family users on macOS Mojave:
Upon booting to macOS Mojave for first time, the system will reboot after the Data & Privacy screen. To fix this issue follow the procedure mentioned here under UPDATE-2 heading.
On macOS Mojave certain webpages will crash upon loading (eg. brew.sh, facebook.com). To fix this issue follow the procedure mentioned here under the UPDATE-5 heading.
To boot 10.15 two things needs to be taken care of:
If you have an EC device with ID
PNP0C09in your DSDT then macOS might get stuck while booting at the initial stage. To fix that you need to make sure your EC device is disabled by making it return status
Zero. You can use a custom SSDT-EC0.aml to do that and if you want to see how it works you can refer to here.
You can change the ID of the EC device. Using this ACPI patch:
Comment Find Replace PNP0C09 to PNPFFFF 41D00C09 41D0FFFF
- When using these SMBIOS profiles
AppleIntelMCEReporter.kextmacOS might panic. To prevent this you need to either use a different SMBIOS or use a disabler kext from here.
