Clover Bootloader for Gigabyte Z390 M Gaming Build


This guide is now deprecated

I have moved my bootloader from Clover to OpenCore. The current guide can is at https://github.com/tspng/gigabyte-z390-m-gaming-opencore


Tested only with macOS Mojave Version 10.14.6.

Hardware

  • Gigabyte Z390 M Gaming, rev. 1.0, Bios F7
  • Intel i7-8700k
  • Gigabyte RX VEGA 56 GAMING OC 8G
  • Corsair Vengeance LPX 32GB (2x16GB) 3200MHz
  • Broadcom BCM94360CD PCIe Adapter for Wi-Fi & Bluetooth 4.0

BIOS Settings

  1. Load optimized defaults
  2. Chipset -> Internal Graphics: Enabled
  3. M.I.T -> Advanced Memory Settings -> Extreme Memory Profile: Profile1

Adjust boot sequence and fan settings to your liking.

Clover

TODO: add some explanation

What Works

  • Sound (Realtek ALC892)
  • Sleep
  • iGPU hardware acceleration
  • Shutdown
  • Wi-Fi (works OOB with Broadcom BCM94360CD card)
  • Bluetooth (works OOB with Broadcom BCM94360CD card)

Notes

iGPU acceleration

Initially, there was a bug when opening images with Preview or using QuickLook. It looks like macOS uses the integrated GPU (iGPU) to render these images and if that's not present, it won't work. After some testing, I could enable the iGPU with the following settings:

  • enable internal graphics in Bios
  • remove WhateverGreen.kext
  • use iMacPro1,1
  • use 0x3E920003 (or AwCSPg== when hex-swapped and base64 encoded) as ig-platform-id
  • add clover ACPI patches
    • GFX0 -> IGPU
    • HECI -> IMEI

Shutdown fix

At first shutdown didn't work, it always rebooted instead. The following changes fixed it for me:

  • add EmuVariableUefi driver
  • use slide=0 boot arg

Aptio Fixes

Do not use OsxAptioFix2Drv-free2000 which many guides recommend for this motherboard.
