OSXFUSE is a successor to MacFUSE
FUSE for OS X allows you to extend Mac OS X's native file handling capabilities via third-party file systems. OSXFUSE is a successor to MacFUSE, which has been used as a software building block by dozens of products, but is no longer being maintained.
As a user, installing the OSXFUSE software package will let you use any third-party file system written atop OSXFUSE or MacFUSE, if you choose to install the MacFUSE compatibility layer.
OSXFUSE supports Mac OS X 10.5 and later (Intel and PowerPC architecture). It is fully compatible with 64 bit kernels and OS X 10.7
