Q 2.3. How can I uninstall MacFUSE?
A: Run the uninstall-macfuse-core.sh script that resides in the Support subdirectory of the MacFUSE file system bundle. The bundle itself resides in /System/Library/Filesystems/ on Mac OS X 10.4.x and in /Library/Filesystems/ on Mac OS X 10.5.x.
For example, to uninstall MacFUSE on Mac OS X 10.4.x, you would run the following command in the Terminal:
sudo /System/Library/Filesystems/fusefs.fs/Support/uninstall-macfuse-core.sh
To uninstall MacFUSE on Mac OS X 10.5.x and above, you would run:
sudo /Library/Filesystems/fusefs.fs/Support/uninstall-macfuse-core.sh
If the file system bundle in your MacFUSE installation doesn't have a Support subdirectory, that means you have an incredibly ancient version of MacFUSE. Please look for the uninstall script within the fusefs.fs/ directory itself.
