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.

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.

Overview of macOS Recognizing An External Hard Drive

When your Seagate, WD my passport, Toshiba or other external hard drive is not recognized by Mac, the first thing is to know which part of the recognition process goes wrong.

So let's take a closer look at how macOS recognizes an external hard drive.

Step 1: The external hard drive is connected to your Mac.

Plugging the external hard drive into a computer will establish the hardware connection, which would supply the external hard drive with power source and data transferring capability. Visually, you can see the external hard drive lighting on and hear it spinning.

Step 2: macOS detects the external hard drive.

After the connection, the Mac would detect that a new storage device is plugged in. It's going to tell the device's type and manufacturer information, which will help macOS know how to load and read this external hard drive.

Step 3: macOS reads the external hard drive.

After recognizing the hardware information of the external hard drive, the Mac will call other system components to read the external hard drive’s type and partition information. If the hard drive is readable by the Mac, a visible disk icon would be formed consequently.

Step 4: macOS recognizes the files in the external hard drive.

Once Mac successfully reads the partition information of the external hard drive, it will go further by calling related programs to recognize the file system of each partition on the external hard drive. A recognized file system will let macOS know how and where your data is stored on the external hard drive, so that it can mount this external hard drive for use.

Step 5: Mac shows the external hard drive for users.

Going so far, macOS has recognized the external hard drive. Meanwhile, other programs get notified that there is a new volume available. But to make it convenient for users to access the data on the drive, it will check the system preferences and decide if users want to automatically mount and show the external hard drive on the desktop and in the finder.

Amazing, right? You probably never know the details. Your Mac has done so many works to recognize an external storage device, while you just simply plug the external drive into the USB port.

However, if one or more steps above fail, the external hard drive would not be recognized by Mac successfully. You can't access it. In this case, we need to know why Mac doesn't recognize your external hard drive.

Namely, we need to check these things:

1. Is your external hard drive properly connected for data transferring and power supply?
2. Is your Mac set to show up mounted external drives on the Finder and desktop?
3. Does Mac read and recognize the partition information of this hard drive?
4. Does Mac recognize the file system of the external hard drive successfully?

Now, let's check them one by one.

First of all, Check the Connections

Don't assume this is unnecessary. It turns out that most of the time, Mac doesn't recognize external hard drives, USB flash drives, pen drives, SD cards, etc. just because the drive is not properly connected.

Since a good connection is a basic condition for secondary hard drives working on the Mac, we need to try these things step by step.

1. Make sure the external hard drive is supplied with power.

Usually, when the external hard drive is supplied with power, the light of the external hard drive is on and blinking. If not, try to check if the external hard drive needs to be externally plugged into the wall outlet. It happens most for some external desktop hard drives like WD Elements and Seagate Desktop devices that don't use USB ports as the power source.

2. Try to re-plug the external hard drive.

This works when you have a drive mounted but your operating system goes to sleep later. Mac won't recognize the external hard drive after the USB port is powered off. When your Mac wakes up again, the drive may not have come out of its slumber. You can reconnect the external hard drive to make it work again.

3. Try another USB port to connect the external hard drive.

Portable hard drives like My Passport and iomega use USB port both for power and data supply. So, if the USB port is loose, damaged, lack of power, or dusty, the connected external hard drive won't be recognized by Mac. You need to change another slot to connect your drive.

4. Try to plug the external hard drive into the USB port slowly.

Strange though, some users notice that the external hard drive would be recognized and work well when they plug it in exceptionally slowly. It may because the USB port is out of shape and unstable. The tricks also work for other storage devices, including thumb drive, USB flash drive, etc.

5. Try another USB cable to connect the external hard drive.

In case the cable is broken, you can try another USB cable to connect the external hard drive to your Mac. And if it's an SD card that is not showing up on Mac, try another card reader. Don't worry if you don't have one right now, you can skip and check other things first.

6. Try another USB hub or USB-C adapter.

Some MacBook after 2015 uses Thunderbolt 3 while some older ones use Thunderbolt 2. This results in incompatibility between different Thunderbolt ports. Thus, if the unrecognized external hard drive is a Type C drive, you can try to access it via another Mac. Instead, if it's a standard USB-A external hard drive and you connect it to Thunderbolt 3 port via USB-C adapter, you can try another USB hub or even another adapter. Sometimes, such adaption makes data transferring unstable.

7. Try to reboot your Mac.

Possibly, you improperly ejected the external hard drive the last time you use it on the Mac. As a result, Mac doesn't recognize the external hard drive this time. It's because macOS would think the USB port is still taken by the unsafely ejected one.

Second, Check if the external hard drive is recognized in System Information

The System Information app provides detailed specifications and other information about your Mac. In some versions of OS X, this app is called System Profiler. So, if the connections are good, you can check whether the connected external hard drive is detected in System Information or not.

• 1. Choose Apple menu > About This Mac.
• 2. Click the System Report button to see more details provided by the System Information.
• 3. Find and click the USB option under the Hardware section.
• 4. Check if the external hard drive is recognized here or not.

If you can find the USB external hard drive in System Information, it means macOS has detected this drive. But why you can't access and open this external hard drive on the desktop and in the Finder? You need to go further and check more things.

Then Check if Mac is Set to Display External Hard Drives

Usually, the external hard drive will be automatically mounted by Mac. Then you can see it on the desktop or in Finder in seconds. But this time, the external hard drive is not showing up on your Mac. Does this mean the external hard drive is not recognized by Mac? Probably not. On the contrary, you need to check if the mounted external hard drive is allowed to show up.

• 1. Go to Finder > Preferences > Sidebar.
• 2. Select External disks under Locations to list your external hard drive in the Finder sidebar.
• 3. Shift to the General tab.
• 4. Check External disks under 'Show these items on the desktop'. Then your connected external hard drive will appear in Finder and on the desktop.

Chances are that Mac won't recognize the external hard drive still. It means it's not the Mac device's fault. Then we should throw light on the external hard drive itself.

Third, Check if Mac Recognizes the Partitions of the External Hard Drive

Any storage devices, including HDD and SSD, need to be partitioned. It makes sure that each section can be managed separately. And partition table or partition map records the necessary partition information of the external hard drive.

Mac won't read the external hard drive further once the partition table is damaged, lost, or corrupted. Fortunately, you can check this in Disk Utility.

Solution 1: Check the external hard drive in Disk Utility

Eternal Dawn Mac Os Update

Disk Utility is a built-in disk repair tool on your Mac. It can manage, erase, check, and repair disks efficiently. It's free and powerful. So, continue reading and check if Mac is reading the disk's partitions.

How to Prevent Data Loss When Mac Doesn't Recognize External Hard Drives?

When the external hard drive is not working normally, the first concern for most users is the important data on the drive. However, if you have tried possible solutions but Mac just doesn't recognize the external hard drive still, how can you access your data?

The good news is, you can recover lost data from this unrecognizable external hard drive with free Mac data recovery software like iBoysoft Data Recovery Software for Mac.

Eternal Dawn Mac Os Download

iBoysoft Data Recovery for Mac is one of the best hard drive data recovery software. It can recover lost data from the external hard drives when it's not recognized, not readable, not working or not showing up on Mac. Moreover, this data recovery software can recover lost data from formatted, corrupted, and unmounted external hard drives. It supports data recovery from APFS, HFS, HFS+, exFAT, FAT32 formatted hard drives.

This program works with macOS Big Sur 11, macOS 10.15 (Catalina), macOS 10.14 (Mojave), macOS 10.13 (High Sierra), macOS 10.12 (Sierra) and OS X 10.11 (El Capitan), 10.10 (Yosemite), 10.9 (Mavericks), 10.8 (Mountain Lion), 10.7 (Lion).

Step 1: Install and launch iBoysoft Data Recovery for Mac on Mac.

After downloading and launching this Mac data recovery software, you can connect the unrecognized external hard drive to your Mac. Later, you can check if the drive is detected and show up in this software.

Step 2: Select the unrecognized external hard drive to scan for lost data.

If you can find the unrecognized external hard drive in the list, click on it. And then choose Scan to search for data on this hard drive.

Step 3: Preview the searching results and recover the target ones.

As we mentioned before, you can't access and view your important data on the unrecognized external hard drive. But with the assistance of iBoysoft Data Recovery for Mac, you get a chance to check the condition of your data by using its Preview feature. Simply filter the scanning result, select the data to preview, and click 'Recover' to get them back.

Last, Check if Mac Has Recognized the File System of the External HDD

The file system manages how your data is stored on the external hard drive. If your partition map seems to be OK, the next thing we need to confirm is that if Mac has recognized the file system of each partition.

So, just go to Finder > Go > Utilities > Disk Utility. You can check if you can see the partition and file system of the USB external hard drive there.

You can see if the file system is NTFS in the right column. You can't write to Windows NTFS on Mac but only read. Probably, you assume that Mac doesn't recognize the NTFS external hard drive because you can't access or open the files. In this case, you can simply solve this problem with an NTFS for Mac software. Or if you don't have important data, you can reformat it as FAT32, exFAT, or APFS (If you can macOS supports it) in Disk Utility.

If it is not NTFS but any other recognizable file system, you can fix the Mac not recognizing external hard drive issue with the following solutions.

Solution 1: Manually mount the external hard drive if it's greyed out in Disk Utility

Chances are that Mac has recognized the external hard drive, but for some reason, Mac fails to automatically mount it. So, if you can see the volumes of the external hard drive with correct disk information (name, file system, storage capacity, etc.), try to force mount the external hard drive in Disk Utility.

• 1. Open Disk Utility.
• 2. Click View option at the upper left, and then choose 'Show All Devices'.
• 3. Right-click on the volume that you want to access, not the external hard drive this time.
• 4. Choose Mount in the context menu.

If nothing happens or macOS reports some errors, keep reading. You can repair the unrecognized external hard drive with First Aid.

Solution 2: Repair the external hard drive with First Aid if you can't mount it

If you can't mount the external hard drive in Disk Utility, the drive might have some file system corruptions. But don't be panic when you hear 'corruption', you still have solutions when Mac can’t recognize the external hard drive's file system.

• 1. Launch Disk Utility as you did before.
• 2. Click View option at the upper left, and then choose 'Show All Devices' in the context menu.
• 3. Select the corrupted volume in the list, not the name of the external hard drive.
• 4. Click on the First Aid button in the top center and then click Run.

If you run First Aid successfully, go to check if the external hard drive is recognized by Mac. If it fails, you need to expand the 'Show Details' option to see more information. Also, if you received an error like 'file system check exit code is 8', ' invalid b tree node size', or other messages, the file system of the external hard drive might be seriously corrupted and can't be repaired.

Read further and check what you can do.

Solution 3: Recover lost data and reformat the corrupted external hard drive

What if First Aid fails to repair the corrupted file system? Well, in this case, we strongly recommend you to recover your important data from the unrecognized external hard drive. It helps especially if you don't have backups. And then you can fix Mac not recognizing external hard drive by reformatting.

• 1. Recover lost data from this unrecognized external hard drive with iBoysoft Data Recovery for Mac.
• 2. Launch Disk Utility and select the unrecognized partitions of the external hard drive.
• 3. Click the Erase at the top.
• 4. Fill in the name and format you want to use, and then click Erase to reformat.
