They are free, fully usable, and no registration is necessary.
Read the software license agreement carefully before using the applications.
You may download, copy, and distribute them at no charge; however, you may not modify the software for distribution.
You can use them for as long a time as you want to do so. If you want to do so, you can make a donation.

These are reliable applications which provide a clean interface to many tasks that would otherwise require complex commands to be typed using a command-line interface.

All the applications are signed by Titanium Software and notarized by Apple and are fully compatible with the light and the dark appearance.
They are available in many languages and are regularly updated (about once a month).
Do you want to translate OnyX into your language, finish an incomplete translation, or suggest some corrections? Have you encountered a problem, anomaly, or misspelling? Do you have suggestions for enhancements to a Titanium Software application? Contact me!

The utilities available on this website do not contain adware, spyware, or any other malware, and do not install any background processes.

Always update your operating system and the applications found here. There is a specific version of the applications for each major version of the operating system.
Use the correct version, and don't try to use a version intended for an earlier operating system.

This provides better compatibility, because there are always significant differences from one major system version to another, although these may not be apparent to the average user.


The development of the old versions is discontinued, and they will be not updated anymore.
However, the applications are always available for download.


To uninstall an application, choose Help > Uninstall [AppName]. In the confirmation message that appears, click the Continue button. The application and the components created while installing and using the application will be removed. Empty the Trash to finish the operation.
