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:

  • 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.

Recommended graphics cards, along with chassis that can power them sufficiently, are listed below.

Mac App Display External Monitor Windows 7

1. 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 your eGPU.

2. If you're using a 13-inch MacBook Pro from 2016 or 2017, always plug eGPUs and other high-performance devices into the left-hand ports for maximum data throughput.

3. macOS High Sierra 10.13.4 and later don't support eGPUs in Windows using Boot Camp or when your Mac is in macOS Recovery or installing system updates.

4. These chassis provide at least 85 watts of charging power, making them ideal for use with 15-inch MacBook Pro models.

5. Playback of HDCP-protected content from iTunes and some streaming services is not supported on displays attached to Radeon 560-based eGPUs. You can play this content on the built-in display on MacBook Pro, MacBook Air, and iMac.

6. If you use Akitio Node with a Mac notebook, you might need to connect your Mac to its power adapter to ensure proper charging.

So you got an external monitor to use with your MacBook or you’ve upped your game and got yourself two of them. Coding will never be the same, I’m telling you. Neither will writing, or research. With all that room you can have a lot of fun with multiple windows arranged just the way you like it.

But when you attach a monitor to your Mac, it will default to mirroring mode. And that’s just the start of all the things you’ll need to change before the awesome productivity dream materializes. To make it easier for you, I’ve compiled all the multi-monitor pitfalls in this article. They include how to use your Mac in clamshell mode, how to configure multi-monitor displays, find awesome panoramic wallpapers and most importantly, how to take care of window management.

A note about connectors: MacBooks come with Thunderbolt ports but they are backwards compatible with mini DisplayPort. Plus mDP to HDMI convertors are pretty cheap. And although I don’t have any personal experience with them, you can also find USB to HDMI convertors if you want to attach more than one display.

Setting Up The Clamshell Mode

If you’ve got a huge external monitor and wish to dock it with a MacBook and attach Bluetooth keyboard and mouse instead of creating a multi-monitor setup, you’ll need to use the clamshell mode.

All you do is connect your display to MacBook via the Thunderbolt adaptor and connect the power cable. Shut the lid and your MacBook now works as a desktop CPU unit. The most important part here is the power cable, without that your Mac will just go to sleep as soon as the lid is closed.

Default Display

If you want to change the default monitor from your MacBook’s screen to one of the connected displays, go to System Preferences ->Displays and you’ll see an Arrangement tab. This lists all the available monitors. First, make sure the Mirror Displays option is deselected.

In there you’ll see the menu bar sitting atop your MacBook’s display. Just click and drag it over to any of your external displays to make that one the default monitor.

Arranging Displays

In the same Arrangement screen you can drag the displays around to change the placement. If you’re mounting your external display above and your MacBook’s screen below, you can go ahead and drop it on top.

Feb 27, 2012  Multi Monitor Wallpaper is supported through an auto-renewing subscription which you can choose to purchase within the app. The subscription is called 'Multi Monitor Wallpaper'. It is an annual subscription. It lets you the full functions of Multi Monitor Wallpaper as described above. Multi monitors software mac free apps.

The display sizes are scaled accordingly. So if you have 27 and 24 inch monitors connected to a 13 inch MacBook, you won’t have any problems figuring out which is which. Replicate your physical monitor setup in this window to make the transition between multiple displays really easy.

Managing Workspaces

Thanks to Mavericks, the multi-monitor capabilities of Macs have improved exponentially. Now every new display gets its own workspace and you can create different desktops or fullscreen apps for individual monitors.

This is great if you plan on using one monitor just for media, to monitor your website, or for social media updates. The Mac will also remember these workspaces so you don’t have to start from scratch every time.

Multi Monitor Wallpapers

When it comes to multi-monitor wallpapers, Mac is kind of weird. When you right-click on the desktop and select Change Desktop Background the app will actually bring up the wallpaper picker window on each different screen.

Of course, there are apps out there that make the process of applying panoramic wallpapers easy but most of them are paid. But you can still do it for free; all you have to do is download panoramic wallpapers that are already cut out for individual screens. You can do that with Wallpaperfusion or dualmonitorbackgrounds.com.

Once you have your cut out wallpapers downloaded, select that folder from the sidebar and choose the relevant images for each screen.

Window Management with BetterTouchTool

And now we come to a grave problem with the Mac that only amplifies itself when you add more displays. Window management. Windows has great window management (had to live up to the name, I guess), where everything is tight and snaps into place.

Mac’s more liberal philosophy spills over into window management as well, where it can’t afford to be. You can’t fling a window to the side with one gesture, telling it to take up exactly 50% of your screen like you can in Windows with the Aero Snap feature.

Wait – actually, you can. Thanks to an awesome free app called BetterTouchTool. I’ve written about it in detail before but it’s basically an app that lets you create custom gestures for trackpad, keyboard and mouse (more on that below), and as a cherry on top, adds the same window snapping features.

Once you’ve activated the Window Snapping feature from the pop-up and given the app accessibility permissions, it’s time to get snapping!

Just click and drag any window to the left or right edge to make it take up half the screen. Moreover, you can go to the corners to allot your window to the relevant quarter of the screen.

Finally, dragging a window up to the menu bar expands the window on the current screen (not to be confused with the fullscreen mode). The best part is that the app gives you a little preview of the exact space the window will take while you’re still holding the mouse on the hot corner.

As you’d imagine, this window snapping doesn’t always work between multiple monitors. But fear not, because alternatives exist and they are discussed below.

Window Management With Multiple Monitors Using Shortcuts

As I said above, BetterTouchTool lets you map specific actions to trackpad, keyboard and mouse shortcuts. And BetterTouchTool has an amazing library of window management actions. You know where this is going.

From all the great actions available, here are the highlights.

  • Move window one space/desktop left or right
  • Maximize window to the next monitor
  • Move window to the next monitor
  • Plus all the window snapping shortcuts and a lot more can be turned into actions

That’s right, using a keyboard/mouse shortcut or just a trackpad gesture, you can fling the current window either to the next monitor or make it full screen when it gets there.

As you can see below, I’m unable to dock the window to the right side of the screen. But thanks to some pre-configured shortcuts, I am able to do so. Using similar keyboard shortcuts, I can fling the window to another monitor as well.

You’ll find a lot of apps out there for doing these things. In my research I found apps ranging from $5 to $20 dedicated to window management. But I’m telling you, you don’t need them. BetterTouchTool will take some time to set up but once done it will be your setup. You can set any kind of crazy keyboard shortcut or trackpad gesture for snapping or moving windows. It will be personal and intuitive, and it will work.

Here’s what I say to everyone after I recommend BetterTouchTool and I’ll say it to you as well.

Go Crazy.

A Simpler Alternative To BetterTouchTool

If you find the feature set overwhelming and don’t want to endlessly customize BTT, try Spectacle. It’s a little app that comes pre-programmed with keyboard shortcuts (that are customizable) for the same kind of window snapping features of BTT. There’s also a shortcut for flinging a window to another display.
