Maintenance Scripts
Mac OS X includes a task manager (launchd) which automates System cleaning by executing the “periodic” utility. This utility runs three BSD standard scripts which perform many maintenance operations.
Cleaning
The Cleaning panel displays six tabs which allow removing the System Cache, User Cache, Internet Files, Fonts Caches, Logs, CrashReporter, and miscellaneous Temporary and Obsolete Files.
Utilities
The Utilities panel allows you to access Unix “man”-pages, to Force Empty the Trash, to quickly find a file or folder, to manage the Process accounting, and to modify the visibility status of a volume, folder, or file.
Automation
The Automation panel is divided into three sections and regroups the main functions of maintenance and cleaning.
Parameters
The Parameters panel displays ten tabs allowing you to personalize your working environment. The system and some Apple applications contain hidden functions that you can enable or disable in this panel.
OnyX Log and Diagnostic Reports
The Log panel displays two tabs which access the OnyX Log or its Diagnostic Reports.
