[EFI Request] Help Needed for HP Z620 – Xeon E5-2690 + RX 570 – macOS Monterey/Sonoma

[Mildred Hubert]

Hello everyone,

I'm trying to build a stable Hackintosh on my HP Z620 workstation, and I need help creating a compatible and clean EFI folder.

I plan to install either macOS Monterey or Sonoma — whichever works better with my hardware. I'm aiming for a fully working system including iMessage, FaceTime, GPU acceleration, USB mapping, and sleep/wake support.

Here are my full system specifications:

🖥️ HP Z620 Workstation:
– CPU: Intel Xeon E5-2690 (8 cores / 16 threads, Sandy Bridge-E @ 2.9 GHz)
– GPU: AMD Radeon RX 570 4GB (Polaris)
– RAM: 32GB DDR3 ECC
– SSD: 500GB SATA
– Audio: Realtek ALC262 onboard
– Ethernet: Intel 82579LM
– BIOS: CSM disabled, VT-d disabled, Legacy USB enabled

🎯 Goals:
– Native GPU acceleration (Metal support)
– Working Ethernet, Audio, and USB
– iMessage / FaceTime / App Store access
– Sleep/Wake support
– Stable system with OpenCore

If anyone has a similar setup or working EFI, I’d really appreciate your guidance or a shared EFI.

Thanks in advance!
