OnyX is a simple and powerful optimization tool to keep your Mac in top shape. This version requires Mac OS Mountain Lion, but other versions are available for Mac OS X 10.2 and higher. The first time you start OnyX, it runs a SMART check on your hard drive, which helps prevent any system crashes and also ensures that volumes are clean so that you don’t run into unusual volume structures. A good help guide helps you use the app with clear explanations and step-by-step instructions.

With OnyX, you can set the number of options that will be checked by the app, which can include Spotlight, iTunes, Expose, and even the Dock. Fonts, user and even system files are completely cleaned up by this application. However, you will need to close the apps in order to clean them properly. This helps Onyx work faster and more efficiently. It also comes with an automation option that helps you keep your hard drive clean at all times and eliminates any issues that come up in this part.

Those who have experienced system issues or trouble starting their Macs will find OnyX a useful utility. The application can also be used to delete logs from a computer or clear the system cache. It also comes with a conversational interface and is a beginner friendly app. It’s also a pretty flexible app. It was only launched in 2003 and has a good track record. All in all, a good choice for all users.
