Essential Tools: OnyX

Mac OS X has a lot of maintenance features built into the operating system. Unfortunately, some of these features only run in the early hours of the morning (if the machine is on, of course) and some can only be run manually.

OnyX has the capability to run all of these manually or you can schedule more convenient times for these to run. It has a lot of features including checking your hard disk for impending failures, checking the structure of system files, extra options for customizing your system that are not present in System Preferences, repairing permissions, and optimizing your system's performance. These are essential tools to ensure the smooth running of your system. When you make a living from your computer, you want it to always perform at the peak of its capabilities.

OnyX is freeware and is available for Mac OS X versions 10.2 - 10.5.
