Hello AMD-OS-X community,
I am trying to boot macOS Sequoia 15.4.1 Recovery bare-metal, but it consistently freezes at or around the last visible message "Registered CoreAnalyticsHub functions" and Caps Lock becomes unresponsive. I am looking for Phoenix-specific advice rather than random OpenCore changes.
Hardware:
Verified:
Tried with no change:
Questions:
1. Has anyone achieved a working bare-metal Sequoia or Tahoe boot on Ryzen 7 8700G/Phoenix with a dedicated AMD GPU?
2. Are known Phoenix-specific CPU/CPUID/kernel compatibility issues distinct from Ryzen 7000 desktop chips?
3. What additional targeted logs/tests would best distinguish Phoenix CPU incompatibility from motherboard-specific ACPI/MMIO problems?
I have a redacted config.plist and OpenCore DEBUG log available on request; original ACPI dumps can also be shared after review. The archived DEBUG log was taken during the cpus=1 test, whereas the restored config no longer has cpus=1. Please note this when comparing them.
Thank you for your help!

Hardware:
- AMD Ryzen 7 8700G Phoenix (8C/16T)
- ASUS TUF GAMING B650-E WIFI, BIOS 3223
- 64 GB DDR5
- PowerColor Radeon RX 5500 XT 8 GB (display connected directly), Radeon 780M iGPU disabled in BIOS
- OpenCore 1.0.8 DEBUG, SMBIOS MacPro7,1
- Linux Mint 22.3 works normally on this machine. macOS Recovery boots from a separate SanDisk USB drive; Linux SSD is untouched.
Verified:
- OpenCore loads and macOS kernel starts.
- Current AMD Vanilla kernel patches report Success in the OpenCore DEBUG log (including the 8-core cpuid_cores_per_package patch).
- Setting Booter/Quirks/DevirtualiseMmio=True fixed a prior boot.efi STOP 0x16 / no usable slide failure.
- Usual boot-args are '-v keepsyms=1'.
Tried with no change:
- Sequoia Recovery and Tahoe Recovery
- different USB 2/3 ports, safe mode (-x)
- dedicated Radeon RX 5500 XT instead of internal graphics
- Resizable BAR off, AMD PCI hotplug patch toggle
- several MMIO whitelist experiments
- cpus=1 (restored original boot args afterward)
- three targeted DSDT ACPI patches for conditional GPP5 device definitions UP00, RHUB, and XH00; OpenCore DEBUG log confirms each patch replaced 1 of 1, but the freeze stayed identical; patches subsequently reverted.
