AMD Vanilla OpenCore
内核二进制补丁，在macOS上实现几乎本机AMD CPU支持。
功能
使macOS能够在AMD CPU上运行。
启用iMessage、Siri、FaceTime、Continuity等。
与自定义XNU内核相比稳定。
缺点
10.14及更低版本中不支持32位（OPEMU）
支持的AMD CPU
族代号示例
15h推土机FX系列
16h捷豹A系列（包括AM4 A系列）
17h和19h Zen Ryzen，第1代、第2代和第3代Threadipper，Athlon 2xxGE
PAT修复补丁的信息
默认启用的修补程序是Algrey的原始修补程序。这将适用于所有GPU，不会影响音频，但不会提高性能。另一个选择是Shaneee的补丁，它将提高AMD GPU的GPU性能，但可以阻止Nvidia GPU启动。当使用HDMI和DP音频时，它也会导致音频问题。您可以选择使用哪个补丁。请不要试图同时使用它们。

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 keep an EFI backup.
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 kernel Quirk ProvideCurrentCpuInfo. OpenCore 0.7.1 or newer is required.
Make sure to enable this quirk or the system won’t boot.
Note for Zen 4: Zen 4 (Ryzen 7000) requires patching for IOPCIFamily.kext.
This patch is enabled by default. Please ensure that you’ve added it to your current config for Zen 4 stability. This patch also allows MSI A520, B550, and X570 boards to boot macOS Monterey and newer.
Core Count patch needs to be modified to boot your system. Find the four algrey – Force cpuid_cores_per_package patches and alter the Replace value only.
macOS Version Replace Value New Value
10.13.x, 10.14.x B8000000 0000 B8 < Core Count > 0000 0000
10.15.x, 11.x BA000000 0000 BA < Core Count > 0000 0000
12.x, 13.0 to 13.2.1 BA000000 0090 BA < Core Count > 0000 0090
13.3 BA000000 00 BA < Core Count > 0000 00
From the table above substitue < Core Count > with the hexadecimal value matching your physical core count. Do not use your CPU’s thread count. See the table below for the values matching your CPU core count.
Core Count Hexadecimal
4 Core 04
6 Core 06
8 Core 08
12 Core 0C
16 Core 10
24 Core 18
32 Core 20
So for example, a user with a 6-core processor should use these Replace values: B8 06 0000 0000 / BA 06 0000 0000 / BA 06 0000 0090 / BA 06 0000 00
Features
Enables macOS to run on AMD CPUs on the fly.
Enables iMessage, Siri, FaceTime, Continuity, etc.
Stable compared to custom XNU kernel.
Disadvantages
No 32-bit support (OPEMU) in 10.14 and lower
Supported AMD CPUs
Family Codename Example
15h Bulldozer FX Series
16h Jaguar A Series (including AM4 A-Series)
17h and 19h Zen Ryzen, Threadripper, Athlon 2xxGE
Information on the fix PAT 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 performance.
The other choice is Shaneee’s patch which will increase GPU performance on AMD GPUs but can stop NVIDIA GPUs from booting. It might also causes audio issues when using HDMI or DisplayPort audio.
The choice is yours. Don’t try to use them both at the same time.
Note on TRX40 systems
Both mtrr_update_action – fix PAT patches are not required on TRX40 systems. Disabling them will result in GPU performance improvements. Test this configuration on a USB drive first in preparation for the unlikely event that something goes wrong. Proceed at your own risk.
Information on the Fix PCI bus enumeration patch
On AM5 motherboards with on-board Thunderbolt/USB4 (e.g. Asus ROG Crosshair X670E Hero, Gene, Extreme; Asus ProArt X670E-Creator), macOS Ventura may not enumerate devices on the PCI bus properly when on-board WiFi and on-board Thunderbolt are both enabled. This patch bypasses the problem. This patch is disabled by default.
Supported macOS versions
macOS High Sierra (10.13)
macOS Mojave (10.14)
macOS Catalina (10.15)
macOS Big Sur (11)
macOS Monterey (12)
macOS Ventura (13)
Instructions
Follow the Dortania OpenCore Install Guide for instructions on how to create the installer USB and setup the config file with these patches.
Do not ask for support on GitHub.
Special notes
Use the latest release of OpenCore to avoid incompatibilities. 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.
