OnyX is a multifunction utility (maintenance, optimization, and personalization). It allows you to run misc tasks of system maintenance, to configure certain hidden parameters of the Finder, Dock, Dashboard, Exposé, Safari, Login window and many Apple's applications, to delete cache, to remove a certain number of files and folders that may become cumbersome, to see the detailed info of your configuration, to preview the different logs and CrashReporter reports, to check the Preferences files and more.

OnyX is delivered with Uninstall Onyx, an independent application allowing to individually remove the components created while installing and using OnyX (preferences, history...). A "Extras" folder contains some icons of replacement created by voluntary sympathetic users.

REQUIREMENTS: Mac OS 10.1.5 and Mac OS 10.2
