OSXFUSE
OSXFUSE is a kernel-level framework that extends macOS's native file-handling capabilities to support third-party file systems. It allows developers and advanced users to write custom file systems as user-space programs, with content sourced from local disk, network, memory, or other sources. OSXFUSE was later rebranded to "FUSE for macOS" by the successor project. The framework is not a standalone application but a system-level library used by file system implementations and the applications that mount them. It requires installation of a system package and, on modern macOS, proper security configuration.
AI Recommendation
1 suggestionOSXFUSE is a framework component, not a standalone app — it cannot be updated independently through the App Store or a generic vendor download. The framework is part of the macFUSE project (the successor to OSXFUSE), and updates must be obtained from the official macFUSE GitHub releases or SourceForge. On Apple Silicon Macs, you must use macFUSE version 4 or later, as kernel extensions cannot run under Rosetta 2. If you have applications or file systems that depend on OSXFUSE, check whether they list macFUSE as a required dependency and download the correct native version for your Mac's processor from the official macFUSE project page. Note that on Apple Silicon with recent macOS versions, you may need to set your Mac's security policy to "Reduced Security" to load the signed kernel extensions. Since OSXFUSE itself has not been actively maintained by its original developer in several years, rely on the macFUSE fork for ongoing updates and Apple Silicon support.
