Hey everyone,

I'm stuck trying to install Sequoia 15.7.1 on my system. Keep getting Error 0xE at ExitBootServices and it hangs on [EB|LOG:EXITBS:START].

Hardware:
  • CPU: AMD Ryzen 7 7800X3D
  • Mobo: Gigabyte B650 EAGLE AX (BIOS F32f)
  • GPU: Gigabyte RX 6950 XT Gaming OC
  • RAM: 32GB DDR5
  • Storage: Kingston NV2 NVMe
  • WiFi/BT: Fenvi FV-T919 (Broadcom BCM94360CD)

BIOS Settings:
  • Fast Boot, Secure Boot, CSM, iGPU, IOMMU = OFF
  • Above 4G Decoding = ON
  • Re-Size BAR = AUTO
  • XHCI Hand-off = ON

What I've tried:
  • NVRAM reset
  • SecureBootModel = Disabled
  • Fresh USB installer (gibMacOS)
  • Only 1 MMIO whitelist entry (4275159040)
My EFI and latest boot log are attached. Any ideas what I'm missing?

Thanks!

I'm assuming you got your kernel patched correctly. Give this a shot your config needs a lot of work but at least get into installer. Have you had any version of macOS installed before?
