Thunderbolt 3-equipped MacBook Pro can use external GPUs, but at a cost. By Mike Wuerthele Thursday, December 01, 2016, 05:45 am PT (08:45 am ET) One of the most frequent complaints about the new. Senior Vice President of Software Engineering Craig Federighi showcased a Thunderbolt 3-based external graphics card enclosure supported by MacOS “High Sierra” and Apple’s latest version of Metal. Appls has rolled out an updated version of macOS and, among other things, it adds support for external graphics cards. That means you should be able to connect a graphics dock to just about any Mac. It can be slow for loading textures, but most of the transformation is done on the video card. Battlefield 3 runs great for an example, as does Skyrim. It just takes longer to load the textures for the level. External GPUs are not needed, just Thunderbolt enabled cases allowing regular desktop video cards. No games saturate the PCI bus.

If you have a Mac mini (2018) with FileVault turned on, make sure to connect your primary display directly to Mac mini during startup. After you log in and see the macOS Desktop, you can unplug the display from Mac mini and connect it to Blackmagic eGPU.
Connect and use Blackmagic eGPU
When you connect Blackmagic eGPU or Blackmagic eGPU Pro to your Mac with a Thunderbolt 3 (USB-C) cable, the eGPU menu bar item appears, indicating that the eGPU is ready for use.
Blackmagic eGPU automatically accelerates the graphics from Metal-based apps on external displays and devices that are connected to the eGPU. You can use Activity Monitor to confirm that your eGPU is in use:
- Open Activity Monitor, which is in the Utilities folder inside Applications.
- Choose Window > GPU History. A graph appears, charting the activity of your computer's internal GPU and Blackmagic eGPU.
To disconnect Blackmagic eGPU, use the menu bar item to safely disconnect the eGPU from your Mac before unplugging the cable.
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 Blackmagic eGPU and Blackmagic eGPU Pro accelerate apps on any display connected to the Mac — including displays built in to the Mac:

- Press Command-I to show the app's info window.
- Select the checkbox next to Prefer external GPU.
- Open the app to use it with the eGPU.

macOS currently doesn't support eGPUs in Windows using Boot Camp or when your Mac is in macOS Recovery, at FileVault login, or installing system updates.
Many 15-inch MacBook Pro notebooks have two graphics processors (GPU)—a discrete GPU and an integrated GPU. The discrete GPU provides substantial graphics performance but uses more energy. The integrated GPU optimizes battery life by using less energy.
Check if the discrete or integrated GPU is in use
