Webroot Software's MacWasher® X provides security on Macintosh OS X by allowing you to power-wash your activity history, protecting your privacy online and offline. Many people do not realize that the operating system and other software programs store information about what they have done, what applications they've launched, what documents they've used, what web sites they've visited, and various other activities they've performed. Therefore, anyone else can see what you have been doing on your Mac, which raises privacy concerns. Furthermore, much of your activity information takes up valuable disk space, and recovering this space can be very beneficial to Mac system performance. Cleaning up the history of your activities can be a tedious chore of manually removing each history file or entry.
