    For GUI mac software, AppCleaner is an easy way to safely and cleanly uninstall it on Mac. However, there is no easy method to uninstall PKG packages on Mac.

    I have written a small script to uninstall PKG packages on my homebin repo. You can easily download it with curl or wget.

    $ curl https://raw.githubusercontent.com/cwchen123/homebin/master/removepkg > removepkg
    $ chmod +x removepkg
    $ mkdir /usr/local/bin
    $ mv removepkg /usr/local/bin

    The script deletes only the files of a package first; then deletes only empty directories of the package. Therefore, other directories will not be deleted mindlessly.

    Use pkgutil --pkgs to see which packages to uninstall. You may use grep to search the package.

    $ pkgutil --pkgs | grep package_name

    Before you really uninstall the package, you may look a while these files with removepkg --dry. Say we want to remove Midnight Commander for Mac.

    $ removepkg --dry hu.louise.mc.midnightCommanderInstaller.usr.pkg

    If you are sure to remove the package, repeat the command with sudo. With the same case:

    $ sudo removepkg hu.louise.mc.midnightCommanderInstaller.usr.pkg
