How can I uninstall fuse-ext2 and macfuse on Mac OS X

Can you please tell me how can I uninstall fuse-ext2 and MacFUSE on Mac OS X?

From the MacFUSE FAQ:

How can I uninstall MacFUSE?

Launch the Mac OS X System Preferences application and go to the MacFUSE preference pane. Click on the "Remove MacFUSE" button. This will uninstall all MacFUSE components except the preference pane itself.

You can keep the MacFUSE preference pane around should you decide to install MacFUSE again in the future. If you do wish to remove it, you do it just like how you would remove any other non-Apple preference pane: In System Preferences, control-click (right-click) on the MacFUSE icon and you will see "Remove ..." as an action.

Only if you had the "Show Beta Versions" button checked in the MacFUSE prefpane, you'll have a property list (plist) file remaining at this point: /Library/Preferences/com.google.macfuse.plist. To remove it, you should uncheck the button before you remove the prefpane as described above.

Note that an official (correct) MacFUSE installation will have a preference pane if you have MacFUSE 2.0 or later installed. If you have an older version of MacFUSE, you can uninstall as follows.

Deprecated Installation Information

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.

in addition to uninstalling MacFUSE (or FUSE for OS X if you installed it), you should also uninstall fuse-ext2 because it's not automatically removed. To do this, type this in terminal:

cd /usr/local/bin
fuse-ext2.uninstall -u
