Trexar has released MacWasher, a program designed to erase unseen Mac-activity data.

The Mac OS, Web browsers and other programs store information about what they have been doing on your Mac and on the Internet.

Those with access to local Mac networks can see previous users activities. As well as representing a security risk, this information wastes hard-drive space. Recovering the space can improve a computers performance.

MacWasher’s AutoWash feature runs in the background and cleans up whatever tracks you want removed. MacWasher also features a ‘bleach’ function; this will delete the washed files utterly, making them unavailable to utilities such as ‘Unerase’ or ‘Undelete’.
