To use an eGPU, a Mac with an Intel processor is required.

I've run in to this exact problem after installing (huge mistake) the new MacOS Big Sur. Only except I'm using the Razer Trinity. Whilst I followed the guide from avaddon which helped 'detect' the mouse. It failed to let me adjust certain keyboard functions/keybinds. The Razer Raptor 27-inch Gaming Monitor is currently $100 off, which leaves it available for $600. However, there are more affordable options. MacOS; Apple’s M1 MacBooks, and gaming keyboard.

An eGPU can give your Mac additional graphics performance for professional apps, 3D gaming, VR content creation, and more.

eGPUs are supported by any Mac with an Intel processor and Thunderbolt 3 ports1 running macOS High Sierra 10.13.4 or later. Learn how to update the software on your Mac.

MacOS Big Sur breaks Razer peripherals. For whatever reason, my Razer Huntsman keyboard does work for the most part but none of the audio controls do anything on the keyboard. In addition, I've tried two different razer mice and neither work at all. Everything worked perfectly before the beta. Download Razer Synapse 2 - Every peripheral. Every preference, profile and Razer add-on. All ready to go, all the time, from anywhere.

An eGPU lets you do all this on your Mac:

  • Accelerate apps that use Metal, OpenGL, and OpenCL
  • Connect additional external monitors and displays
  • Use virtual reality headsets plugged into the eGPU
  • Charge your MacBook Pro while using the eGPU
  • Use an eGPU with your MacBook Pro while its built-in display is closed
  • Connect an eGPU while a user is logged in
  • Connect more than one eGPU using the multiple Thunderbolt 3 (USB-C) ports on your Mac2
  • Use the menu bar item to safely disconnect the eGPU
  • View the activity levels of built-in and external GPUs (Open Activity Monitor, then choose Window > GPU History.)

eGPU support in apps

eGPU support in macOS High Sierra 10.13.4 and later is designed to accelerate Metal, OpenGL, and OpenCL apps that benefit from a powerful eGPU. Not all apps support eGPU acceleration; check with the app's developer to learn more.3

In general, an eGPU can accelerate performance in these types of apps:

  • Pro apps designed to utilize multiple GPUs
  • 3D games, when an external monitor is attached directly to the eGPU
  • VR apps, when the VR headset is attached directly to the eGPU
  • Pro apps and 3D games that accelerate the built-in display of iMac, iMac Pro, MacBook Air, and MacBook Pro (This capability must be enabled by the app's developer.)

You can configure applications to use an eGPU with one of the following methods.

Use the Prefer External GPU option

Starting with macOS Mojave 10.14, you can turn on Prefer External GPU in a specific app's Get Info panel in the Finder. This option lets the eGPU accelerate apps on any display connected to the Mac—including displays built in to iMac, iMac Pro, MacBook Air, and MacBook Pro:

  1. Quit the app if it's open.
  2. Select the app in the Finder. Most apps are in your Applications folder. If you open the app from an alias or launcher, Control-click the app's icon and choose Show Original from the pop-up menu. Then select the original app.
  3. Press Command-I to show the app's info window.
  4. Select the checkbox next to Prefer External GPU.
  5. Open the app to use it with the eGPU.

You won't see this option if an eGPU isn't connected, if your Mac isn't running macOS Mojave or later, or if the app self-manages its GPU selection. Some apps, such as Final Cut Pro, directly choose which graphics processors are used and will ignore the Prefer External GPU checkbox.

Set an external eGPU-connected display as the primary display

If you have an external display connected to your eGPU, you can choose it as the primary display for all apps. Since apps default to the GPU associated with the primary display, this option works with a variety of apps:

  1. Quit any open apps that you want the eGPU to accelerate on the primary display.
  2. Choose Apple menu  > System Preferences. Select Displays, then select the Arrangement tab.
  3. Drag the white menu bar to the box that represents the display that's attached to the eGPU.
  4. Open the apps that you want to use with the eGPU.

If you disconnect the eGPU, your Mac defaults back to the internal graphics processors that drives the built-in display. When the eGPU is re-attached, it automatically sets the external display as the primary display.

About macOS GPU drivers

Mac hardware and GPU software drivers have always been deeply integrated into the system. This design fuels the visually rich and graphical macOS experience as well as many deeper platform compute and graphics features. These include accelerating the user interface, providing support for advanced display features, rendering 3D graphics for pro software and games, processing photos and videos, driving powerful GPU compute features, and accelerating machine learning tasks. This deep integration also enables optimal battery life while providing for greater system performance and stability.

Apple develops, integrates, and supports macOS GPU drivers to ensure there are consistent GPU capabilities across all Mac products, including rich APIs like Metal, Core Animation, Core Image, and Core ML. In order to deliver the best possible customer experience, GPU drivers need to be engineered, integrated, tested, and delivered with each version of macOS. Aftermarket GPU drivers delivered by third parties are not compatible with macOS.

The GPU drivers delivered with macOS are also designed to enable a high quality, high performance experience when using an eGPU, as described in the list of recommended eGPU chassis and graphics card configurations below. Because of this deep system integration, only graphics cards that use the same GPU architecture as those built into Mac products are supported in macOS.

Supported eGPU configurations

It's important to use an eGPU with a recommended graphics card and Thunderbolt 3 chassis. If you use an eGPU to also charge your MacBook Pro, the eGPU's chassis needs to provide enough power to run the graphics card and charge the computer. Check with the manufacturer of the chassis to find out if it provides enough power for your MacBook Pro.
