Jim Mitchell Designs today announced the release of Yasu 1.0.3, the latest update to its maintenance utility for Mac OS X. “Designed to be a quick first line of defense for solving OS X related issues, Yasu was developed with System Administrators who service large groups of workstations in mind, enabling them to perform a specific group of maintenance tasks quickly within a few clicks, rather than endlessly typing shell script commands in the Terminal application.” Yasu is distributed as donationware.
