Mac OS X supports a handful of common file systems—HFS+, FAT32, and exFAT, with read-only support for NTFS. It can do this because the file systems are supported by the OS X kernel. Formats such as Ext3 for Linux systems are not readable, and NTFS can’t be written to. But that doesn’t mean that there aren’t occasions when you’d want to use one of them. With FUSE (Filesystem in Userspace) you can.

  • MacFUSE comes with its own installer package which greatly simplifies the whole process: simply follow the on screen indications. The package makes sure that the macFUSE Core is installed, but also.
  • FUSE for macOS (or, the kernel extension formerly known as osxfuse) is a project dating back to 2011. It in turn is based on even older projects, such as MacFUSE, the Linux FUSE module, and even some code open sourced by Apple.

FUSE mimics the kernel’s handling of file systems and allows OS X to both interact with unsupported formats and use many other storage routines, some of which are rather creative. With FUSE, such formats can be handled very similarly to natively supported file systems and allow you to interact with drives your Mac otherwise could not read to or write from. Here’s how you can put FUSE to work.

Gdb apfs-fuse (In gdb): set args run (And if/when it crashes): backtrace (When you're finished): quit And then send the output of backtrace to me. Adding -d 1 to options might help as well, but be aware that it will generate a lot of output on the text console. The performance issues on macOS persist. Many of Inkscape's old bug reports still need to be tested and migrated to the new bug and feature request reporting page. While some progress has already been made, we still need your help with that task. All (migrated and new) open issues for the project are listed on GitLab.

What is FUSE?

FUSE works by providing a behind-the-scenes interface between Apple’s storage routines and specially programmed modules that you install on your Mac. These modules can read various storage formats, and then, with FUSE’s help, can be mounted and accessed as a drive-like storage medium. For instance, if you have several cloud-based storage accounts, you can write a small module that will connect all of these services with FUSE. You can then mount them as a single volume on the system, much like you’d plugged in a USB drive.

FUSE has its limitations, however. File system access performs less well than with native kernel support, for example. On the other hand it offers vast flexibility in storage options. For instance, in addition to using multiple Web storage services as a single drive, FUSE modules have been written to use PNG image files for storing drive data. In this case a mounted storage device’s data will be spread out among a number of garbled PNG images (a perhaps amusing, but frankly bizarre, way to manage your files).

These approaches are experimental and fun, but FUSE does have useful options that allow you to expand your Mac’s file system support beyond the natively supported formats, including allowing access to Ext3 drives, full NTFS support, and even letting you mount SFTP shares as local drives.

To get started, download and install FUSE for OS X. Once installed, you can install the desired module for the various file systems you would like to manage on your Mac. Keep in mind that some modules are well tested and regularly used, while others might not be. And some are more integrated in OS X while others will require Terminal commands to mount their file systems.


For NTFS support, one of the more popular FUSE modules is NTFS-3G, an open-source package from Tuxera. To acquire it you have several options. You can download an older precompiled version of NTFS-3G. The more technically inclined can download and compile the latest source code either directly from Tuxera or by using a package manager like MacPorts or Fink.

Once installed, an attached NTFS drive should be automatically recognized and mounted using NTFS-3G and FUSE. In addition, you should be able to format drives as NTFS using Disk Utility.

Using Ext3

For Linux Ext2 and Ext3 file systems, you can use the fuse-ext2 module, and then mount Ext2 and Ext3 drives using Terminal (automatic mounting and managing in Disk Utility is not yet supported). Follow these steps:

1. Install the ext2 FUSE module.

2. Enable Disk Utility’s Debug menu, using the following command in Terminal, followed by opening Disk Utility and choosing the option in the Debug menu to show all partitions:

defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

3. Attach your ext2/ext3 drive and when it appears in Disk Utility (grayed out), select the volume and press Command-I to produce its Information window. In this window note the device name, which should be something like “disk2s2,” or “disk3s2.”

4. Create a new folder somewhere in your user account to use as a mount point for the drive (I recommend a folder called “mount” directly in your home folder).

5. Mount the drive using the following Terminal command syntax, replacing the device name and mount path with that of your disk and the path to the mount folder you created:

fuse-ext2 /dev/disk2s2 /Volumes/mountpoint

This will mount the drive as read-only, but you can use the “-o force” flag in the following manner to implement write support:

fuse-ext2 -o force /dev/disk2s2 /Volumes/mountpoint

After performing these steps, the ext2/ext3 drive will be fully accessible from the folder you created and specified to use as the mount point.


In addition to supporting locally attached drives, FUSE can be used to access remote systems and mount their shared resources locally. Granted, you can do this with SMB and AFP protocols when you have enabled File Sharing on a remote Mac, but since enabling SSH with the Remote Login service also enables SFTP access, you can use the SSHFS module for FUSE to access your Mac’s files directly over the encrypted SFTP connection.

1. Download and install the SSHFS module (available from the FUSE for OS X page).

2. As with managing Ext2 and Ext3 drives, create a folder on your Mac to use as a mount point

3. In Terminal, run a command similar to the following to access a folder on the remote system and mount it at the folder you created:

sshfs [email protected]:/remote/directory/path /local/mount/point

In this command, /remote/directory/path is the path to the desired folder on the remote server that you have access to. (Alternatively, you can just use a forward slash to mount the root directory.) The /local/mount/point is the full path on your current system to the new mount folder. For example, if you want to mount the entire root file system from the remote computer at a folder called “mount” in your home directory, then you would run a command similar to the following:

sshfs [email protected]:/ ~/mount

While these approaches with FUSE can be used to mount various file system formats, for the most part, you will not need special approaches for handling hard drives and other storage media. The built-in support in OS X is enough for most uses, but there are some special cases where the storage management options offered by FUSE can be useful.

Welcome to Docker Desktop! The Docker Desktop for Mac user manual provides information on how to configure and manage your Docker Desktop settings.

For information about Docker Desktop download, system requirements, and installation instructions, see Install Docker Desktop.


The Docker Preferences McCAD EDA Tools lite. menu allows you to configure your Docker settings such as installation, updates, version channels, Docker Hub login,and more.

Choose the Docker menu > Preferences from themenu bar and configure the runtime options described below.


On the General tab, you can configure when to start and update Docker:

  • Automatically check for updates: By default, Docker Desktop is configured to check for newer versions automatically. If you have installed Docker Desktop as part of an organization, you may not be able to update Docker Desktop yourself. In that case, upgrade your existing organization to a Team plan and clear this checkbox to disable the automatic check for updates.

  • Start Docker Desktop when you log in: Automatically starts Docker Desktop when you open your session.

  • Include VM in Time Machine backups: Select this option to back up the Docker Desktop virtual machine. This option is disabled by default.

  • Use gRPC FUSE for file sharing: Clear this checkbox to use the legacy osxfs file sharing instead.

  • Send usage statistics: Docker Desktop sends diagnostics, crash reports, and usage data. This information helps Docker improve and troubleshoot the application. Clear the check box to opt out.

  • Show weekly tips: Displays useful advice and suggestions about using Docker.

  • Open Docker Desktop dashboard at startup: Automatically opens the dashboard when starting Docker Desktop.


The Resources tab allows you to configure CPU, memory, disk, proxies, network, and other resources.


On the Advanced tab, you can limit resources available to Docker.

Advanced settings are:

  • CPUs: By default, Docker Desktop is set to use half the number of processorsavailable on the host machine. To increase processing power, set this to ahigher number; to decrease, lower the number.

  • Memory: By default, Docker Desktop is set to use 2 GB runtime memory,allocated from the total available memory on your Mac. To increase the RAM, set this to a higher number. To decrease it, lower the number.

  • Swap: Configure swap file size as needed. The default is 1 GB.

  • Disk image size: Specify the size of the disk image.

  • Disk image location: Specify the location of the Linux volume where containers and images are stored.

You can also move the disk image to a different location. If you attempt to move a disk image to a location that already has one, you get a prompt asking if you want to use the existing image or replace it.

File sharing

Use File sharing to allow local directories on the Mac to be shared with Linux containers.This is especially useful forediting source code in an IDE on the host while running and testing the code in a container.By default the /Users, /Volume, /private, /tmp and /var/folders directory are shared. If your project is outside this directory then it must be addedto the list. Otherwise you may get Mounts denied or cannot start service errors at runtime.

File share settings are:

  • Add a Directory: Click + and navigate to the directory you want to add.

  • Apply & Restart makes the directory available to containers using Docker’sbind mount (-v) feature.

Tips on shared folders, permissions, and volume mounts

  • Share only the directories that you need with the container. File sharing introduces overhead as any changes to the files on the host need to be notified to the Linux VM. Sharing too many files can lead to high CPU load and slow filesystem performance.

  • Shared folders are designed to allow application code to be edited on the host while being executed in containers. For non-code items such as cache directories or databases, the performance will be much better if they are stored in the Linux VM, using a data volume (named volume) or data container.

  • If you share the whole of your home directory into a container, MacOS may prompt you to give Docker access to personal areas of your home directory such as your Reminders or Downloads.

  • By default, Mac file systems are case-insensitive while Linux is case-sensitive. On Linux, it is possible to create 2 separate files: test and Test, while on Mac these filenames would actually refer to the same underlying file. This can lead to problems where an app works correctly on a Mac (where the file contents are shared) but fails when run in Linux in production (where the file contents are distinct). To avoid this, Docker Desktop insists that all shared files are accessed as their original case. Therefore, if a file is created called test, it must be opened as test. Attempts to open Test will fail with the error No such file or directory. Similarly, once a file called test is created, attempts to create a second file called Test will fail. For more information, see Volume mounting requires file sharing for any project directories outside of /Users.)


Docker Desktop detects HTTP/HTTPS Proxy Settings from macOS and automaticallypropagates these to Docker. For example, if you set yourproxy settings to http://proxy.example.com, Docker uses this proxy whenpulling containers.

Your proxy settings, however, will not be propagated into the containers you start.If you wish to set the proxy settings for your containers, you need to defineenvironment variables for them, just like you would do on Linux, for example:

For more information on setting environment variables for running containers,see Set environment variables.


You can configure Docker Desktop networking to work on a virtual private network (VPN). Specify a network address translation (NAT) prefix and subnet mask to enable Internet connectivity.

Docker Engine

The Docker Engine page allows you to configure the Docker daemon to determine how your containers run.

Type a JSON configuration file in the box to configure the daemon settings. For a full list of options, see the Docker Enginedockerd commandline reference.

Click Apply & Restart to save your settings and restart Docker Desktop.

Command Line

On the Command Line page, you can specify whether or not to enable experimental features.

Experimental features provide early access to future product functionality.These features are intended for testing and feedback only as they may changebetween releases without warning or can be removed entirely from a futurerelease. Experimental features must not be used in production environments.Docker does not offer support for experimental features.

For a list of current experimental features in the Docker CLI, see Docker CLI Experimental features.

You can toggle the experimental features on and off in Docker Desktop. If you toggle the experimental features off, Docker Desktop uses the current generally available release of Docker Engine.

You can see whether you are running experimental mode at the command line. IfExperimental is true, then Docker is running in experimental mode, as shownhere. (If false, Experimental mode is off.)


Docker Desktop includes a standalone Kubernetes server that runs on your Mac, sothat you can test deploying your Docker workloads on Kubernetes. To enable Kubernetes support and install a standalone instance of Kubernetes running as a Docker container, select Enable Kubernetes.

For more information about using the Kubernetes integration with Docker Desktop, see Deploy on Kubernetes.


Reset and Restart options


On Docker Desktop Mac, the Restart Docker Desktop, Reset to factory defaults, and other reset options are available from the Troubleshoot menu.

For information about the reset options, see Logs and Troubleshooting.

Fuse For Macos Mojave


The Docker Desktop Dashboard enables you to interact with containers and applications and manage the lifecycle of your applications directly from your machine. The Dashboard UI shows all running, stopped, and started containers with their state. It provides an intuitive interface to perform common actions to inspect and manage containers and existing Docker Compose applications. For more information, see Docker Desktop Dashboard.

Add TLS certificates

You can add trusted Certificate Authorities (CAs) (used to verify registryserver certificates) and client certificates (used to authenticate toregistries) to your Docker daemon.

Add custom CA certificates (server side)

All trusted CAs (root or intermediate) are supported. Docker Desktop creates acertificate bundle of all user-trusted CAs based on the Mac Keychain, andappends it to Moby trusted certificates. So if an enterprise SSL certificate istrusted by the user on the host, it is trusted by Docker Desktop.

To manually add a custom, self-signed certificate, start by adding thecertificate to the macOS keychain, which is picked up by Docker Desktop. Here isan example:

Or, if you prefer to add the certificate to your own local keychain only (ratherthan for all users), run this command instead:

See also, Directory structures forcertificates.

Note: You need to restart Docker Desktop after making any changes to thekeychain or to the ~/.docker/certs.d directory in order for the changes totake effect.

For a complete explanation of how to do this, see the blog post AddingSelf-signed Registry Certs to Docker & Docker Desktop forMac.

Add client certificates

You can put your client certificates in~/.docker/certs.d/<MyRegistry>:<Port>/client.cert and~/.docker/certs.d/<MyRegistry>:<Port>/client.key.

When the Docker Desktop application starts, it copies the ~/.docker/certs.dfolder on your Mac to the /etc/docker/certs.d directory on Moby (the DockerDesktop xhyve virtual machine).

  • You need to restart Docker Desktop after making any changes to the keychainor to the ~/.docker/certs.d directory in order for the changes to takeeffect.

  • The registry cannot be listed as an insecure registry (see DockerEngine. Docker Desktop ignores certificates listedunder insecure registries, and does not send client certificates. Commandslike docker run that attempt to pull from the registry produce errormessages on the command line, as well as on the registry.

Directory structures for certificates

If you have this directory structure, you do not need to manually add the CAcertificate to your Mac OS system login:

The following further illustrates and explains a configuration with customcertificates:

You can also have this directory structure, as long as the CA certificate isalso in your keychain.

To learn more about how to install a CA root certificate for the registry andhow to set the client TLS certificate for verification, seeVerify repository client with certificatesin the Docker Engine topics.

Install shell completion

Docker Desktop comes with scripts to enable completion for the docker and docker-compose commands. The completion scripts may befound inside Docker.app, in the Contents/Resources/etc/ directory and can beinstalled both in Bash and Zsh.


Bash has built-in support forcompletion To activate completion for Docker commands, these files need to becopied or symlinked to your bash_completion.d/ directory. For example, if youinstalled bash via Homebrew:

Add the following to your ~/.bash_profile:



In Zsh, the completionsystemtakes care of things. To activate completion for Docker commands,these files need to be copied or symlinked to your Zsh site-functions/directory. For example, if you installed Zsh via Homebrew:


Fuse For Macos Ntfs


Fish-shell also supports tab completion completionsystem. To activate completion for Docker commands,these files need to be copied or symlinked to your Fish-shell completions/directory.

Create the completions directory:

Now add fish completions from docker.
