Email me when discounted: 
Yasu was originally created with System Administrators who service large groups of workstations in mind, Yasu (Yet Another System Utility) was made to do a specific group of maintenance tasks quickly within a few clicks, rather than needing to endlessly type shell script commands in the Terminal application.

Yasu allows system administrators, as well as the average user, to conveniently run various system level Unix shell scripts in order to perform maintenance routines and clear the many 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 more...

What's New

Version 2.9:
  • Finally 100% compatible with OS X 10.9.
  • Distributed as a developer signed application, so you know it's from me.

  • Complete re-write of cache clearing routines for these operating systems.
  • Changed the order of processes run to make more sense.
  • Blank administrator passwords now work on OS X 10.9.
  • Many small bug fixes & improvements.

Requirements

  • OS X 10.7 or later

Very glad to hear of the update. I have used the following programs Onyx, Cache Out X, C Cleaner and even PrivacyScan but whenever I use YASU it improves the overall performance of the operating systems--speeds things up with no down side that I have seen. Presently I have SL, Lion, ML and Mavericks....and YASU the program I go to first and most often.

Has anyone tried this on Mavericks? Any issues? This is so effective on all my operating systems...SL, Lion and ML.

In as much testing as I've done (which isn't really all that thorough), Yasu has performed well with Mavericks. I've also not had any issues reported by Mavericks users. It should be safe -- along with standard disclaimer...

I downloaded and ran YASU 2.8.0 for my iBook G4 Power PC OSX 10.5.8 and it deleted all of my pictures and videos. The recommendator said that that was not supposed to happen, l but it did!

Im not sure if this was Yasu's fault or a coincidence, but after running Yasu in 10.8 I had a very rough time restarting.
Mac mini was rebooting but screen was dark.
Had to reset PRAM and hit option key and select my HD to restart.
As I said it may not be Yasu's fault but then again...

Please update to version 2.8.1. That solves this issue.
