macfuse is a framework for implementing custom file systems in user space. It utilizes a macOS kernel extension to bridge the operating system kernel's virtual file system layer to a user-process daemon.
This project allows the implementation of file system logic outside of the kernel to improve system stability and simplify development. It enables the mapping of remote data, network resources, or memory to a local folder so they can be accessed through standard system interfaces.
The framework supports the development of cross-platform storage by providing a portable interface for consistent behavior across different operating systems. It allows for the interception of file system operations to route requests to background services or user-space processes.
