Onyx is the kind of program you research before using and given its potential reach into your operating system’s components, it behooves you to read up on it or look into some YouTube tutorial videos to get familiar with how to operate Onyx, which items to repair via clicking checkboxes in the menus, which items to avoid, and how to safely use the program.

The older versions are continuously hosted on the Titanium Software website, and readily available to download if you’re working with an old version of Mac OS X from yesteryear that needs to be repaired. Onyx is also available in a variety of flavors, with each release being geared towards a macOS operating system and its specific under-the-hood features and components: Mac OS X 10.1 Puma, Mac OS X 10.2 Jaguar, Mac OS X 10.3 Panther all the way through macOS 11 Big Sur, with a macOS Monterey version coming soon. Onyx also combines a unique, bare-bones approach to its user interface while offering an incredible level of customization as to what files are affected during a repair. The program is excellent at digging into deeply-rooted chunks of macOS, setting and repairing Unix-level functions that would otherwise only be accessed through the Mac’s Terminal program and the command line, and rooting through odd settings to restore functionality after you’ve slogged through strange errors and weird behaviors from your Mac. With Onyx at hand, permissions can be repaired, databases rebuilt, file structures reorganized, hard disk structures checked, and indexes restored.
