OSXFUSE

OSXFUSE provides a framework for creating user‑space file systems on macOS. It implements the FUSE (Filesystem in Userspace) API, allowing developers to write file‑system code that runs outside the kernel while still presenting a standard file‑system interface to the operating system and applications. By loading a kernel extension and exposing a user‑space daemon, OSXFUSE enables custom storage solutions, network mounts, or virtual file systems to be accessed like any native macOS volume.

The software is intended for developers and system administrators who need to integrate non‑standard storage back‑ends or experiment with new file‑system concepts without modifying the macOS kernel. It is compatible with macOS 10.12 and later, and supports typical file‑system operations such as reading, writing, and directory traversal.

OSXFUSE is considered stable and is distributed as an open‑source project, with documentation covering installation, building user‑space file systems, and troubleshooting common issues. It serves as a core component for many macOS‑based file‑system projects.
