Cocktail

Cocktail was born as an application to simplify the use of maintenance operations via UNIX commands and now it is one of the essential applications for Mac when tuning them up.

No, you don't need a terminal window to do the maintenance. Cocktail gives you access from its interface.

You decide what to tune up: disks, system, files, network, interface or pilot.

Checking the status of the disks, repairing file settings, changing startup mode, cleaning system cache,... everything is much easier thanks to Cocktail.
