How to completely remove Fuse for Mac OS X, MacFUSE, NTFS-3G I want to switch to Tuxera NTFS for better support. But don’t know how to uninstall all these apps before completely switching to Tuxera.

I also install fuse_wait.pkg but I am not sure how to unistall .pkg file. 

I followed this video for NTFS-3G installation in Mac OS X 10.10 (Yosemite).
If you have followed those instructions then you've installed three packages.

fuse_wait just replaces a single file of the NTFS-3G install with an updated version. So you don't really need to do anything to uninstall this package; when you remove NTFS-3G it should automatically remove that updated version.

To remove NTFS-3G either open the NTFS-3G preference pane and click on the Uninstall button, or run the script at /System/Library/Filesystems/ntfs-3g.fs/Support/uninstall-ntfs-3g.sh.

To uninstall FUSE for OS X open the FUSE for OS X system preference pane and click the Uninstall button.

If the two preference panes are still there after running both uninstalls, then just right-click on them and select the "Remove ... Preference Pane" option.

And reboot your Mac.

To confirm that the file are gone you could run the following commands in Terminal. Hopefully you shouldn't get any results.

 pkgutil --pkgs | grep fuse
 kextstat | grep fuse
