POIKKEUS This pull-down contains a full range of typical diagnostics, including cleaning and rebuilding files - as well as a utility guaranteed to gut any trash. Perform Disk Utility from the desktop, working invisibly in the background, or trash your caches; when it's on, all you see is a glowing MainMenu icon.
MainMenu is an all-purpose diagnostic - not quite as heavy-duty as Onyx - but it's also faster and less obtrusive.
