An eGPU can give your Mac additional graphics performance for professional apps, 3D gaming, VR content creation, and more.
eGPUs are supported by any Thunderbolt 3-equipped Mac1 running macOS High Sierra 10.13.4 or later. Learn how to update the software on your Mac.
An eGPU lets you do all this on your Mac:
The entire Mac line transitioned to Intel processors in 2006, first ones in January, and the last in August. Mac OS X Snow Leopard launched in 2009 as Intel only.
- 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.)
- Pages is a powerful word processor that lets you create stunning documents, and comes included with most Apple devices. And with real-time collaboration, your team can work together from anywhere, whether they’re on Mac, iPad, iPhone, or using a PC.
- The Mac transition to Intel processors was the process of changing the central processing unit (CPU) of Apple Inc.' S line of Mac computers, as well as its server offerings at the time, from PowerPC to Intel x86 processors. The transition became public knowledge at the 2005 Worldwide Developers Conference (WWDC), when then Apple CEO Steve Jobs made the announcement to transition away from the.
- Before running out to buy Microsoft Word (or another industrial-strength and expensive) word processing program for your Mac, remember that Apple includes a respectable word processor with OS X. The program is TextEdit, and it call s the Applications folder home.
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:
- Quit the app if it's open.
- 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.
- 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.
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:
- Quit any open apps that you want the eGPU to accelerate on the primary display.
- Choose Apple menu > System Preferences. Select Displays, then select the Arrangement tab.
- Drag the white menu bar to the box that represents the display that's attached to the eGPU.
- 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.
Recommended graphics cards, along with chassis that can power them sufficiently, are listed below.

Some of us are old enough to recall life before word processors. (It wasn’t that long ago.) Consider this sentence:
How did we survive in the days before every last one of us had access to word processors and computers on our respective desks?
That’s not a great sentence — it’s kind of wordy and repetitious. The following sentence is much more concise:
It’s hard to imagine how any of us got along without word processors.
The purpose of this mini-editing exercise is to illustrate the splendor of word processing. Had you produced these sentences on a typewriter instead of a computer, changing even a few words would hardly seem worth it. You would have to use correction fluid to erase your previous comments and type over them. If things got really messy, or if you wanted to take your writing in a different direction, you would end up yanking the sheet of paper from the typewriter in disgust and begin pecking away anew on a blank page.
Word processing lets you substitute words at will, move entire blocks of text around with panache, and apply different fonts and typefaces to the characters. You won’t even take a productivity hit swapping typewriter ribbons in the middle of a project.
Before running out to buy Microsoft Word (or another industrial-strength and expensive) word processing program for your Mac, remember that Apple includes a respectable word processor with OS X. The program is TextEdit, and it call s the Applications folder home.
The first order of business when using TextEdit (or pretty much any word processor) is to create a new document. There’s really not much to it. It’s about as easy as opening the program itself. The moment you do so, a window with a large blank area on which to type appears.
Have a look around the window. At the top, you see Untitled because no one at Apple is presumptuous enough to come up with a name for your yet-to-be-produced manuscript.
Notice the blinking vertical line at the upper-left edge of the screen, just below the ruler. That line, called the insertion point, might as well be tapping out Morse code for “start typing here.”
Indeed, you have come to the most challenging point in the entire word processing experience, and it has nothing to do with technology. The burden is on you to produce clever, witty, and inventive prose, lest all that blank space go to waste.
Processor For Mac
Okay, got it? At the blinking insertion point, type with abandon. Type something original like this:
It was a dark and stormy night
If you typed too quickly, you may have accidentally produced this:
It was a drk and stormy nihgt
Fortunately, your amiable word processor has your best interests at heart. See the dotted red line below drk and nihgt? That’s TextEdit’s not-so-subtle way of flagging a likely typo. (This presumes that you’ve left the default Check Spelling as You Type activated in TextEdit Preferences.)
Mac Arm Processor
You can address these snafus in several ways. You can use the computer’s Delete key to wipe out all the letters to the left of the insertion point. (Delete functions like the backspace key on the Smith Coronayou put out to pasture years ago.) After the misspelled word has been quietly sent to Siberia, you can type over the space more carefully. All traces of your sloppiness disappear.
Processor For Macs
Delete is a wonderfully handy key. You can use it to eliminate a single word such as nihgt. But in this little case study, you have to repair drk too. And using Delete to erase drk means sacrificing and and stormy as well. That’s a bit of overkill.
Processor For Machine Learning
Use one of the following options instead:
- Use the left-facing arrow key (found on the lower-right side of the keyboard) to move the insertion point to the spot just to the right of the word you want to deep-six. No characters are eliminated when you move the insertion point that way. Only when the insertion point is where it ought to be do you again hire your reliable keyboard hit-man, Delete.
- Eschew the keyboard and click with the mouse to reach this same spot to the right of the misspelled word. Then press Delete.
Now try this helpful remedy. Right-click anywhere on the misspelled word. A list appears with suggestions. Single-click the correct word and, voilà, TextEdit instantly replaces the mistake. Be careful in this example not to choose dork.
