FUSE for macOS 4.1.0

FUSE for macOS 4.1.0

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 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.

What's New:

Version 4.1.0:
  • Add support for building macFUSE on Apple Silicon.
  • Add native Apple Silicon support to the updater and uninstaller. macFUSE does no longer require Rosetta 2 on Apple Silicon Macs.
  • Drop support for macOS 10.9, 10.10 and 10.11. Installer packages that are built on Apple Silicon Macs do not work on macOS versions before 10.12 due to the use of SHA-256 signatures instead of SHA-1 signatures.
  • Fix auto_cache file modification detection. In case auto_cache is enabled the kernel extension watches out for remote modification time changes. If a remote change is detected, the file's cache is invalidated. We need to make sure not to invalidate the file's cache in case the modification time changes due to local writes.
  • Remove file name length check in lookup. This improves support for non-latin languages. File names are passed in NFD form and might therefore be longer than their NFC representation. The NFC representation must not be longer than 255 bytes.
  • Add support for dark mode to installer plugin.
  • The license has changed. Starting with the 4.0.0 release, redistributions bundled with commercial software are not allowed without specific prior written permission. This includes the automated download or installation in the context of commercial software. Please contact Benjamin Fleischer.
