[SUCCESS] MSI PRO x870-P R9 9950x RX6800 Sequoia 15.7.5

[kitabzo]

After a few days of tinkering I finally reached the point where everything I wanted boots perfectly from OpenCore.

macOS, Windows, and Linux all working on the same machine with a clean boot picker.

Thought I’d share the setup and results since AM5 Hackintosh builds are still a bit uncommon.

System Specs​

CPU: AMD Ryzen 9 9950X

GPU: AMD Radeon RX 6800 16GB

Motherboard: MSI PRO X870-P WIFI

RAM: 32GB DDR5 6000 MT/s


Storage

• Samsung 990 EVO – Windows + Zorin
• WD SN770 – macOS

Networking

• Realtek RTL8126 5GbE (RTL812xLucy.kext)
• Wi-Fi not working yet (waiting on a Fenvi/Broadcom card)

SMBIOS: MacPro7,1

Bootloader: OpenCore

Kexts Used​

• Lilu.kext
• VirtualSMC.kext
• AppleALC.kext
• AppleMCEReporterDisabler.kext
• NVMeFix.kext
• RestrictEvents.kext
• RTL812xLucy.kext
• USBToolBox.kext
• UTBMap.kext
• WhateverGreen.kext
• AMDRyzenCPUPowerManagement.kext
• SMCAMDProcessor.kext
• SMCRadeonSensors.kext

Operating Systems​

• macOS Sequoia 15.7.5
• Windows 11
• Zorin OS 18.1 (Linux)

All three boot directly from OpenCore picker.

What Works​

• GPU acceleration
• Sleep / wake
• Ethernet
• Audio
• Triple boot via OpenCore
• AppleID
• iPhone call relay (surprisingly works)
• iMessage
• Dev workloads extremely smooth

What Doesn't Work (Yet)​

• Wi-Fi / Bluetooth (waiting for Fenvi Broadcom card)
• Some scheduler behavior causes core bouncing in single-core benchmarks
• Minor OpenCore cosmetic stuff

If anyone is running Zen 5 Ryzen Hackintosh builds, I’d love to compare notes.

Also curious if anyone managed to improve single-core boost behavior on macOS with AMD CPUs.
