(The semantics of "local" and "remote" are debatable, but that is another discussion.) As far as the macFUSE VFS is concerned, any and all volumes are remote in that their backing store lives across the kernel-user boundary, in a program that encapsulates backing store knowledge. Technical reasons aside, there are arguments to justify that all macFUSE volumes are, in fact, "remote". Moreover, Disk Arbitration also gets involved in mounting and unmounting "local" volumes - this may be undesirable in some cases. This would have been fine if the entire file system lived in the kernel, but in macFUSE's case, the user space file system program would also want to (exclusively) open the disk device. This happens before control passes to macFUSE and mounting can proceed. In doing so, the kernel would make sure that the device is not currently in use (for one, to disallow multiple mounts of the same device). Itself open the device node and pass it to macFUSE. ![]() Such a real disk device node in macFUSE's case is problematic: at mount time, for a local volume, the kernel would It supports Intel and Apple Silicon Macs. ![]() The macFUSE software package is compatible with macOS 10.9 and later versions. (Some of its code is based on the FreeBSD implementation of FUSE.) The user-space library ( libfuse), which provides the developer-visible FUSE API, has numerous OS X specific extensions and features. The in-kernel file system is specific to OS X and is not based on Linux FUSE. MacFUSE has two major components: an in-kernel loadable file system and a user-space library ( libfuse). Another crude way to look at this would be to think of macFUSE as something that makes OS X work like a microkernel for the purpose of writing/running file systems. You can think of it as a library for easily developing OS X file systems. MacFUSE is software that allows you to write arbitrary file systems as user space applications. What is macFUSE? Is it the same as FUSE on Linux? The resulting distribution package can be found in /tmp/osxfuse/distribution.If the question you have is not answered here, try posting it to the Run the following command in the cloned repository to build FUSE for macOS from source. To clone the source repository into a newly created subdirectory named osxfuse in the current working directory, run the following command in Terminal: git clone -recursive -b support/osxfuse-3 git:///osxfuse/osxfuse.git osxfuse The Xcode tools packages can be obtained from (free Apple Developer ID required). The "Command Line Tools" package is needed to generate BridgeSupport metadata for amework because of a bug in gen_bridge_metadata (hard coded path to cpp). Homebrew: brew install autoconf automake libtool gettext MacPorts: sudo port install autoconf automake libtool gettext Install MacPorts or Homebrew and run the following commands in Terminal to install the required tools: Xcode 4.3 and newer versions do not include autotools and libtool, that are needed to build libosxfuse. It builds a distribution package compatible with the currently running version of macOS. The build script automatically locates all supported installations of Xcode in your Applications folder. One of these APIs is a superset of the FUSE API, that originated on Linux.ĭue to the fact that 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.įor more information visit the website of the FUSE for macOS Project. You can use the provided APIs to develop numerous types of file systems, whose content can come from a local disk, from across the network, from memory, or any other source. It is a successor to MacFUSE, which has been the basis of many products, but is no longer being maintained. ![]() The FUSE for macOS software package provides multiple APIs for developing file systems for OS X 10.9 to macOS 10.12. FUSE for macOS allows you to extend macOS via third party file systems.
