Installing Mojave on a HP Z400 (AMD RX 570)

2 posts in this topic

Recommended Posts

I had a working Mojave installation on my HP Z400 with clover and from a VMware image.  (Because i had a Nvidia 8800GT with no Metal support.) I found a cheap AMD RX 570 card on the local market.
So i did a reinstall with a clean Mojave version from de App Store. Before the new card everything worked fijne exept the video card.
(My Englisch is not great sorry!)

The hardware:

  • HP Z400 Motherboard in standard ATX case.  (Some powercable and other hacks needed.)
  • Xeon W3520 (4 cores  2,67Ghz)
  • 6x 2GB DDR3 non ECC
  • Sapphire Radeon RX 570 4G Nitro+
  • SATA Harddisk
  • BIOS version 03.61 (last)


BIOS Settings:

File\Default Setup

  1. Restore Factory Settings as Default (You may get some new options)
  2. Apply Defaults and Exit (Reboot)

Storage\Storage Options

  1. Legacy Diskette - Write Disable
  2. Sata Emulation - RAID+AHCI

Security\Device Security

  1. legacy Diskette - Device hidden
  2. Embedded Security - Device Device hidden

Power\Hardware Power Management

  1. Everyting - Enable


  1. Hyper-Threading – Enable


Install disk:

  1. Download the complete Mojeva Install App from de Appstor
  2. Make a install USB stick
  3. use the Terminal app and command
    “sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/USB -- /Applications/Install\ macOS\ Mojave.app”
    Where USB is te name of the USB stick
  4. Install Clover v2.4k r4844
    Change Install Location and choose  “Install macOS Mojave”


  • Install clover in the ESP
  • Boot Sectors\Install boot0af in MBR
  • Clover for Bios(legacy) booting\ Clover EFI 64-Bits SATA
  • BIOS Drivers, 64 Bit\ApfsDriverLoader-64     (For Apfs in Clover)
  • Everything else unchanged
  • Install

Open Clover Configurator
And open config.plist from the EFI on the USB stick


  1. Boot\Arguments   dart=0
  2. Graphics - RadeonDeInit
  3. Kernel and Kext Patches   DellSMBIOSPatch
  4. SMBIOS Choose Mac Pro 5.1




And place those kexts in Clover\kexts\Other (Zie Attachments)

  • FakeSMC.kext (Mandatory)
  • AHCIPortInjector_v1.0.0_Micky1979.kext (SATA)
  • IOAHCIBlockStorageInjector_v1.0.0_Micky1979.kext (Fix SATA)
  • NullCPUPowerManagement_v1.0.0d2_tgwbd.kext (Support CPU)
  • VoodooHDA_v2.87.kext (Sound)

And install disk is ready
My install was Mojave 10.14.2 and with succes updated to 10.14.3


Everything is working great de only problem i have found is Mojave sees 7 memory slots and there are 6 slots in the system.
When i define te memory slots in Clover the problem is solved see the image.

      Hello, insanely kind people! 
      I had full working Speedstep on my system with El Capitan, but after installing Mojave i cant make it working again!
      Help me please. Actually system is working only with NullCPUPowerManagement.kext. As soon as i remove it from Extensions directory i've got kernel panic at the boot.
      I tried to put SSDT.aml from my previous ElCapitan clover, tried to make new by different utilities, but still no luck.

      My system is:
      Pentium G3258
      Asus Z97-K USB 3.1
      Nvidia GTX 670

      i''m attaching my new clover.plist of Mojave and old El Capitan one, which makes Speedstep fully working and overclocking my little Pentium from 3.2 to 4.5GHz. Now i see huge speed loss without SpeedStep on Mojave  Please help, anybody! Also im attaching my working SSDT.aml from El Capitan.
      El Capitan SSDT.aml
      El Capitan config.plist
      Mojave config.plist

      Hi, is Qualcomm Atheros AR956x compatible with MacOS Mojave 10.14.3?
      I don't have access to another Mac, so I downloaded the following files:
      Build is 10.14.3
      These were direct downloads from Apple Servers. If I extract them all I can build a Install macOS Mojave.app from them. I have tried various things in order to get the Mojave Patcher to accept the .app but I cannot get it to boot. The USB key it creates doesn't look proper as some of the files end up on the root of the disk, such as Base. and when it's finished flashing it changes the usb key's name to OS X Base.
      Could someone be of assistance and provide me with a tree print out of the file structure for Install macOS Mojave.app please?
      Thank you,
