Favored Freeware: Yasu

Yasu is a Cocoa application wrapper built with AppleScript Studio that allows system administrators, as well as standard users, to conveniently run various system level Unix shell scripts in order to perform maintenance routines and clear the various cache files used by OS X. Yasu was designed to be a simple, first line of attack for a workstation that has started “acting up.” More often than not, a thorough purge of the cache files of a Mac will bring its behavior back into line.

Pros: Yasu provides a convenient interface for running most system maintenance tasks.

Cons: None significant.

Note: As of v2.0, Yasu is no longer offered as freeware. It is now available under a shareware license and “the cost is a whopping $3.50.” Because of Yasu’s incredible value, it will remain part of my Favored Freeware list as an honorary entry.
