Installation steps 


  • No special steps for macOS, just plug-n-play.


  • Disconnect eGPU
  • Use Bootcamp assistant to install Windows Pro 10 1903 V1 (build 18362.30) with the iso downloaded from here:  https://tb.rg-adguard.net/public.php
  • As soon as installation is complete and you land on the Windows 10 desktop for the first time, you'll need to run gpedit.msc to disable automatic Windows updates.
  • On the Local Group Policy Editor windows, navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Updates. Click on Configure Automatic Updates.  Click on Edit policy setting to open the Configure Automatic Updates dialog.  On the Configure Automatic Updates dialog, select Enabled in the left pane, in the Options section click on the Configure Automatic Updating Combo Box and in the dropdown list select Notify for download and notify for install.  If followed correctly, this will stop automatic installation of Windows Updates and only notify you that there are updates to install, which of course you don't want to do.
  • Now you can install the Bootcamp PKG which should already be open and ready for installation.
  • Reboot
  • Download the September 2021 Red Gaming Edition Drivers (version 21.9.1) from Bootcampdrivers.com and extract.
  • Go to your device manager.  Click View and select "Devices by Connection".  Disable the the FaceTime Camera (Webcam).  Not quiet sure if this is really necessary, but followed another guide that recommended this.
  • Reboot into safe mode. 
  • Go to where you extracted the Red Gaming Edition Drivers from Bootcampdrivers.com and double-click on the DDU application.  This will extract DDU into its own folder.  Go to that folder and double-click Display Driver Uninstaller.  When the settings dialog appears, enable EVERY OPTION under AMD and Nvidia.  MOST IMPORTANTLY, enable "Prevent downloads of drivers from Windows Update" at the bottom.
  • In "Select Device Type" drop-down, select GPU
  • In "Select Device" drop-down, select Nvidia.
  • Select "Clean and DO NOT Restart".  Once complete, don't exit out of DDU.
  • In "Select Device" drop-down, select AMD.
  • Select "Clean and Restart".
  • Once you are back at the desktop following your restart, NOW CONNECT YOUR EGPU to the front left TB3 port.  I had issues with bluetooth working if I used the TB3 ports on the right side.  Windows will start installing your device with multiple bells and whistles.
  • Go to where you downloaded the Red Gaming Edition Drivers and double-click "setup".  This will start the AMD driver installation and will detect your configuration.  Once your configuration is detected, there will be an "Additional Options" drop-down where you'll need to enable the "Factory Reset" option.  Proceed with the install.  Your system will reboot, but keep the eGPU connected.  Once back at the desktop, the AMD driver installation will automatically continue.  Once the driver installation completes, reboot.
  • OPTIONAL - Go to Device Manager and disable the dGPU (5500M).  Not sure if this is beneficial, but figured I would disable it in hopes of keeping MBP as cool as possible.
  • That's it.  At this point I had my eGPU working fine without any issues.

Compared to my previous PowerRed Devil 5700 XT 8GB card, macOS score went from 3410 to 3994 (~17% increase), which is very underwhelming given 6900 XT price tag.  However, Windows score went from 4236 to 6627 (~56% increase) which is pretty noticeable.

@karant, You’ll want to run a modern Metal benchmark like Basemark GPU to get a meaningful result in MacOS. 

As a comparison point, my previous 5700 XT card’s Basemark score for Metal was 6512 with settings @ 2160p res / High quality.

OpenGL is ancient history.

Hi @karant,

You may be able to avoid disabling Windows 10 updates by using the Win10 20H2 ISO.  I'd read about it in other forum member AMD builds before I tried it myself.  Like you, I was using the Win10 1903 v1 ISO for AMD eGPU builds.  But for my '18 Mac mini + Vega56 eGPU build, I used the Win10 20H2 ISO  And it worked great!  I'm not suggesting you re-install just to test Win10 20H2.  But the next time you upgrade maybe give it a try.
