Onyx doesn't have one specific use, and there isn't really anything to compare it to, essentially this program does a variety of different things for the Max OS. First of all, it can verify the system files to ensure everything is there and your system is stable. It can also configure different areas of certain Mac programs like Finder, Fock, Safari, Mail, and Quicktime. More specifically, it can remove unnecessary files that are being stored by these programs and clear their cache to improve performance with your system as a whole as well as those individual programs.

Key Features of OnyX:

• Completely free to download and install
• Compatible with the Mac Operating System
• Checks vital system files for complete integrity, in turn preventing system crashes and slowed performance
• Clears popular program caches and temporary files to improve both system performance and individual program performance

The system check alone is enough reason to try Onyx, so get started today!
