OSXFUSE 2.7.1 is a third party application that provides additional functionality to OS X system and enjoys a popularity among Mac users. However, instead of installing it by dragging its icon to the Application folder, uninstalling OSXFUSE 2.7.1 may need you to do more than a simple drag-and-drop to the Trash. Download Mac App Remover. Hi All, I just did a SMC reset and then went to System Preferences to check if any power options were changed. Thankfully, they were the same as before the reset. I did notice, however, a new icon in the System Preferences; the was an icon for FUSE. I searched the net and think I have a.

Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a 'bridge' to the actual kernel interfaces.

FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, Android and macOS.^[2]

FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License.

History[edit]

The FUSE system was originally part of AVFS (A Virtual Filesystem), a filesystem implementation heavily influenced by the translator concept of the GNU Hurd.^[3] It superseded Linux Userland Filesystem, and provided a translational interface using lufis in libfuse1.

FUSE was originally released under the terms of the GNU General Public License and the GNU Lesser General Public License, later also reimplemented as part of the FreeBSD base system^[4] and released under the terms of Simplified BSD license. An ISC-licensed re-implementation by Sylvestre Gallon was released in March 2013,^[5] and incorporated into OpenBSD in June 2013.^[6]

FUSE was merged into the mainstream Linux kernel tree in kernel version 2.6.14.^[7]

The userspace side of FUSE, the libfuse library, generally followed the pace of Linux kernel development while maintaining 'best effort' compatibility with BSD descendants. This is possible because the kernel FUSE reports its own 'feature levels', or versions. The exception is the FUSE fork for macOS, OSXFUSE, which has too many differences for sharing a library.^[8] A break in libfuse history is libfuse3, which includes some incompatible improvements in the interface and performance, compared to the older libfuse2 now under maintenance mode.^[9]

As the kernel-userspace protocol of FUSE is versioned and public, a programmer can choose to use a different piece of code in place of libfuse and still communicate with the kernel's FUSE facilities. On the other hand, libfuse and its many ports provide a portable high-level interface that may be implemented on a system without a 'FUSE' facility.

Operation and usage[edit]

What Is Osxfuse For Mac Os

To implement a new file system, a handler program linked to the supplied libfuse library needs to be written. The main purpose of this program is to specify how the file system is to respond to read/write/stat requests. The program is also used to mount the new file system. At the time the file system is mounted, the handler is registered with the kernel. If a user now issues read/write/stat requests for this newly mounted file system, the kernel forwards these IO-requests to the handler and then sends the handler's response back to the user.

FUSE is particularly useful for writing virtual file systems. Unlike traditional file systems that essentially work with data on mass storage, virtual filesystems don't actually store data themselves. They act as a view or translation of an existing file system or storage device.

In principle, any resource available to a FUSE implementation can be exported as a file system.

Applications[edit]

On-disk file systems[edit]

Conventional on-disk file systems can be implemented in user space with FUSE, e.g. for compatibility or licensing reasons.

• Linear Tape File System: Allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives.
• NTFS-3G and Captive NTFS, allowing access to NTFS filesystems.

Layering file systems[edit]

FUSE filesystems can create a view of an underlying file system, transforming the files in some way.

• EncFS: Encrypted virtual filesystem
• FuseCompress, Fuse-ZIP, CompFUSEd: Compressed virtual filesystems

Archive and backup file systems[edit]

FUSE filesystems can expose the contents of archives or backup sets without having to first extract them.

• Borg (backup software): Deduplicating backup program that allows backup archives to be mounted as FUSE filesystems.
• Restic: Free, fast, efficient and secure backup software uses FUSE to be able to browse all of your backup snapshots as a regular file system
• SPFS A file system for Spectrum Protect, designed to mount the backup server filespace anywhere on your server, and use the features included from the backup server ( encryption, de-duplication, compression, filtrering etc). This is a WORM file system.

Remote/distributed file system clients[edit]

• CernVM-FS: A distributed read-only software distribution system, implemented as a POSIX filesystem in user space (FUSE) using HTTP transport, to deliver software in a fast and reliable fashion at global scale.
• CloudStore (formerly, Kosmos filesystem): By mounting via FUSE, existing Linux utilities can interact with CloudStore

• Lustre Cluster filesystem will use FUSE to allow it to run in userspace, so that a FreeBSD port is possible.^[10] However, the ZFS-Linux port of Lustre will be running ZFS's DMU (Data Management Unit) in userspace.^[11]
• MinFS: MinFS is a fuse driver for Amazon S3 compatible object storage server. MinFS^[12] lets you mount a remote bucket (from a S3 compatible object store), as if it were a local directory.
• MooseFS: An open source distributed fault-tolerant file system available on every OS with FUSE implementation (Linux, FreeBSD, NetBSD, OpenSolaris, OS X), able to store petabytes of data spread over several servers visible as one resource.
• ObjectiveFS: Distributed filesystem with object store backend (Amazon S3, Google Cloud Storage or S3-compatible object store) using FUSE
• s3fs: Gives the ability to mount an S3 bucket as if it were a local file system.
• Sector File System: Sector is a distributed file system designed for large amount of commodity computers. Sector uses FUSE to provide a mountable local file system interface.
• SSHFS: Provides access to a remote filesystem through SSH.
• Transmit: A commercial FTP client that also adds the ability to mount WebDAV, SFTP, FTP and Amazon S3 servers as disks in Finder, via MacFUSE.
• WebDrive: A commercial filesystem implementing WebDAV, SFTP, FTP, FTPS and Amazon S3
• WikipediaFS: View and edit Wikipedia articles as if they were real files
• Wuala: Was a multi-platform, Java-based fully OS integrated distributed file system. Using FUSE, MacFUSE and CBFS Connect respectively for file system integration, in addition to a Java-based app accessible from any Java-enabled web browser (service discontinued in 2015).

Other[edit]

• GVfs: The virtual filesystem for the GNOME desktop
• rvault: A secure and authenticated store for secrets and small documents using envelope encryption with one-time password (OTP) authentication. It uses FUSE to expose the vault as a file system.
• EmojiFS: A FUSE filesystem that allows you to manipulate custom emojis on your various Slacks and Discords.

Fuse4X project is not supported anymore. Most of its functionality has been merged into OSXFUSE. Please use OSXFUSE for future development.

Fuse4X allows you to extend Mac OS X's native file handling capabilities via 3rd-party file systems. It can be used as a software building block other products.

As a user, installing the Fuse4X software package will let you use any 3rd-party file system written atop Fuse4X.

As a developer, you can use the Fuse4X SDK to write numerous types of new file systems as regular user-mode programs. The content of these file systems can come from anywhere: from the local disk, from across the network, from memory, or any other combination of sources. Writing a file system using Fuse4X is orders of magnitude easier and quicker than the traditional approach of writing in-kernel file systems. Since Fuse4X file systems are regular applications (as opposed to kernel extensions), you have just as much flexibility and choice in programming tools, debuggers, and libraries as you have if you were developing standard Mac OS X applications.

In more technical terms, Fuse4X implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on Mac OS X (10.5 and above). It provides API compatible with the FUSE (File-system in USEr space) API that originated on Linux. Therefore, many existing FUSE file systems become readily usable on Mac OS X.

The Fuse4X software consists of a kernel extension and various user-space libraries and tools. It comes with C-based and Objective-C based SDKs. If you prefer another language (say, Python or Java), you should be able to create file systems in those languages after you install the relevant language bindings yourself.

Goal and Vision of the project

Fuse4X has been forked off MacFuse project with intention to make it 'FUSE reference implementation'. Most Fuse filesystems are developed on Linux and later ported to other platforms such as FreeBSD/MacOSX/Solaris. All these filesystems expect that libfuse works the same way on all supported platforms. In general this is not true for MacFuse.

MacFuse (that for severals years was de-facto the main implementation of libfuse on macosx) had never compatibility as a project goal. The MacFuse author had motto 'MacFuse is not Fuse' and over the years MacFuse became incompatible with the upstream project. While other forks (for FreeBSD/NetBSD/...) are developed closely with the Linux version, MacFuse development was more like a ghetto without dialogue with the rest of the FUSE community.

The goal of Fuse4X project is to develop FUSE implementation that is fully-compatible with the upstream project. Fuse4X pays a lot of attention to communication with the FUSE community as well. Fuse4X developers try to contribute its changes to the upstream project when possible.

It is highly recommended for cross-platform applications to use Fuse4XOSXFUSE. Also its binary distribution includes macfuse compatibility layer that allows legacy applications run together with fuse4x-specific applications.
