Hi,

I'm Jeremy Choulant, an independent developer based in Royan, France. I just achieved what appears to be the first publicly documented bare-metal macOS Sequoia install on an AMD EPYC server platform — fully active SMT, daily-driver stable. I thought it might interest your readers.

The build:
  • Supermicro H11SSL-i v2.0 (server board, IPMI/BMC)
  • AMD EPYC 7302P (Zen 2 Rome, 16C / 32T)
  • AMD Radeon RX 6800 16 GB
  • 64 GB DDR4 ECC RDIMM
  • Crucial P310 2 TB NVMe
  • macOS Sequoia 15.7.7 (build 24G720), OpenCore 1.0.5
Results:
  • 32 SMT threads recognized by macOS (hw.ncpu = 32, HTT flag active)
  • Geekbench 6 Single: 1217 / Multi: 8207 (slightly above the cross-OS world average for this CPU)
  • GPU OpenCL: 89 761 (Mac Pro 2019 territory)
  • Native Ethernet, audio, USB; stable daily driver
  • Public Geekbench run (verifiable): https://browser.geekbench.com/v6/cpu/18196255
Why it matters: EPYC powers most modern data centers. macOS has never been documented as booting natively on this class of hardware — only Proxmox / KVM passthrough setups existed. The hard parts were the EPYC IOHub high-MMIO regions (over 1 TB), BMC firmware collisions with kernel placement, and SMT activation on AMD server boards (CpuTopologyRebuild is Intel-only and silently triple-faults on Zen 2 — confirmed empirically). 120+ failed boots over two weeks of debugging across forums in seven languages.

Full write-up (French, browser-translates cleanly): Hackintosh AMD EPYC Sequoia : Première mondiale bare metal
For full disclosure: this is a personal/educational project. I'm not releasing my config.plist, EFI or kernel patches. macOS on non-Apple hardware violates Apple's EULA.
Happy to discuss the technical hurdles, run live demos over video call, or provide any verification you need.
Best regards,

This cracked me up
"Ich habe das aus persönlicher Überzeugung getan, und das steht auch ganz klar in meinem Blog. Ich habe lediglich Beiträge verfasst, um die Welt darauf hinzuweisen, dass es möglich ist und dass wir es geschafft haben. Jetzt stehe ich gerne für persönliche Fragen zur Verfügung."

Seriously, I am getting a bit tired with all these blatant and very ham handed attempts for visibility and reputation building.
