It’s to Joël Barrière’s credit that the program is able to dive into system components as well as it does, and Barrière’s does his homework and listens to user feedback to create an excellent freeware program while only asking for donations in return if the customer is satisfied with the product. There are some handy FAQ links on the Titanium Software website as to common issues Onyx works to address.

Onyx has never tried to be a jack of all trades like some of the other Mac utilities, nor does it go out of its way to welcome the user with a tutorial video. OnyX is a multifunction utility that you can use to verify the startup disk and the structure of its system files run tasks of cleaning and computer. The Restore Defaults option under the Maintenance tab also comes in handy and provides an easy escape if you’ve changed a system setting and things appear to have gotten out of hand.
