AppZapper 1.8 released has released AppZapper 1.8 for Mac OS X 10.4 and above.

AppZapper allows you to confidently uninstall virtually any application, widget, preference pane and plugin as easily as it was installed — just drag and drop. AppZapper finds leftover support files and allows users to put them in the trash with a single click.

AppZapper 1.8 introduces the much requested User Authentication, UnZap (cmd-z undo of a Zap), and fixes for localized application names.

Mac OS X lets you install most applications with a simple drag to the applications folder. Many people decide they don’t want an application and drag it to the trash. However, this does not remove the extra preferences, caches, and other support files generated during launch — files that can sometimes be many times larger than the applications themselves. AppZapper helps clean up these leftover files, files that many Mac users don’t even know exist. By creating a non-destructive way to remove unwanted files, AppZapper is the uninstaller of choice for Mac OS X with more than 800,000 downloads to date. Cleaner system folders allow your system to run more smoothly while saving space you can use for today’s media-intensive lifestyles.

Individuals can purchase AppZapper for $12.95 and a Family Pack registers all members of the same household for only $18. The free shareware version allows you to zap five times prior to purchase. For more information, visit:


  1. Friends (MW!),
    This sounds good. Does anyone know whether AppZapper works well at removing software that was installed prior to AppZapper itself? That is, does it need to log all the files when a new application is installed, or is it just very smart? I have looked on their website, but I can’t see an answer to this.

  2. Appzapper doe not log anything and can uninstall things that were installed prior to installing appzapper. it does this (i think) by checking a few “known” locations for installed files (such as ~library/application_support etc).

    macnabb, prefs etc are not trashed when the app is trashed, unless an “unsinstaller” is specifically run for that app (some apps include uninstallers. otherwise the prefs stay there).
