What is FUSE for macOS?
FUSE (Filesystem in Userspace) is an open-source software interface that extends the file handling capabilities of the Mac OS, with support for NTFS and many other file systems. The CentreStack Mac Client relies on FUSE to mount the cloud drive among other things. Some users have also reported FUSE errors while using a Mac through a remote session. Aug 09, 2018 Download Fuse for macOS for free. Fuse for macOS is a macOS port of The Free Unix Spectrum Emulator (Fuse) (an emulator of the 1980s home computer and various clones).
Therefore, many existing FUSE file systems become readily usable on Mac OS X. That said, MacFUSE has numerous user- and developer-visible interfaces that are specific to Mac OS X. FUSE for macOS allows you to extend macOS's native file handling capabilities via third-party file systems. It is a successor to MacFUSE, which has been used as a software building block by dozens of products, but is no longer being maintained. As a user, installing the FUSE for macOS software package will let you use any third-party.

Features
As a user, installing the FUSE for macOS software package will let you use any third-party FUSE file system. Legacy MacFUSE file systems are supported through the optional MacFUSE compatibility layer.
As a developer, you can use the FUSE SDK to write numerous types of new file systems as regular user space 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 FUSE is orders of magnitude easier and quicker than the traditional approach of writing in-kernel file systems. Since FUSE 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 macOS applications.
How It Works
In more technical terms, FUSE implements a mechanism that makes it possible to implement a fully functional file system in a user-space program on macOS. It provides multiple APIs, one of which is a superset of the FUSE API (file system in user space) that originated on Linux. Therefore, many existing FUSE file systems become readily usable on macOS.
The FUSE for macOS 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.
The filesystems repository contains source code for several exciting and useful file systems for you to browse, compile, and build upon, such as sshfs, procfs, AccessibilityFS, GrabFS, LoopbackFS, SpotlightFS, and YouTubeFS.

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]

Convert YouTube videos to MP4 videos and MP3 audio supported by iPhone/ iPad/iPod on Mac.
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 exceptions 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]
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.
fusermount commandFUSE 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
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
