Yet Another Yasu Update
Unlike Windows, OS X is great at taking care of itself. Built in periodic maintenance such as cron jobs (a holdover from the FreeBSD on which OS X is based) and on-the-fly disk defragmentation of the journaled file system make OS X essentially self sufficient when it comes to keeping itself running smoothly, so much so that many users never even consider running third party maintenance tools.
However, for older systems and systems in special usage cases such as computer labs, the built in tools aren't always enough to stop system slowdown and other issues. That's where programs like Yasu come in. Yasu, standing for Yet Another System Utility, is a donationware utility designed for administrators of large groups of systems and allows easy running and automation of cache and log cleanup, permissions repair, and other similar activities.
YASU 1.3.9 fixes some early issues with Intel/PPC compatibilities, and is availalbe from the developers site.
