UpdateWasher is useful in a way that after an OS X update, simply double click on UpdateWasher, where ever it may be, and it will run OS X's built in maintenance scripts, repair permissions essential to keeping your Mac bloat-free and then reboots your system to make sure everything is in ship-shape. Best of all, UpdateWasher requires no user input at all! Just click OK, and wait for the application. When UpdateWasher is done doing maintenance, it will notify you when it's done! This version requires a registered version of Cocktail.
