UpdateWasher

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 ask you if you would like to reboot (recommended), and will reboot your Mac in 15 seconds. What's New
