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 often than not, a thorough purge of the cache files of a Mac will bring its behavior back into line.
Addressed an issue where Yasu would not remove user cache files that had incorrect permissions.
Changed how Yasu logs errors so they're easier to find in the log file (at the very end now).
When Yasu does log errors, the application will perform the final steps (restart, shut down, etc.) after user has dismissed the error notification panel.
The Cancel button on the run panel now disables as tasks are being performed, and re-enables between tasks.
