macFUSE

macFUSE adds support for FUSE file systems to macOS, allowing user‑space implementations of file systems that can source data from local storage, networks, memory, or combinations thereof. By intercepting file‑system operations and forwarding them to a user‑space process, it enables third‑party FUSE file systems to be used without requiring kernel extensions, and the newer FSKit backend lets these run entirely in user space on recent macOS versions.

For end users, installing macFUSE provides the runtime needed to mount and interact with FUSE file systems, though the individual file‑system implementations must be installed separately. For developers, macFUSE supplies APIs such as libfuse2, libfuse3, and macFUSE.framework, supporting languages like Swift, Objective‑C, Python, Java, Go, Rust and others, making development, debugging, and testing comparable to standard macOS applications.

The package includes the necessary libraries, tools, and framework, and its cross‑platform FUSE API facilitates reuse of file‑system code across macOS, Linux, and Windows (via third‑party implementations), offering a consistent experience without kernel‑level complexity.
