Important information

Here is some essential information that you must know before using OnyX.

Software License Agreement

PLEASE READ THIS SOFTWARE LICENSE AGREEMENT (“LICENSE”) CAREFULLY BEFORE USING THE ONYX SOFTWARE. BY USING THE ONYX SOFTWARE, YOU ARE AGREEING TO BE BOUND BY THE TERMS OF THIS LICENSE.

ONYX IS DONATIONWARE (FREEWARE). IT'S A GRATIS APPLICATION AND IS FREELY USABLE. YOU MAY COPY AND DISTRIBUTE IT AT NO CHARGE; HOWEVER, YOU MAY NOT MODIFY THE SOFTWARE FOR DISTRIBUTION. YOU CAN USE IT FOR AS LONG AS YOU WANT TO DO SO.

YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT, TO THE EXTENT PERMITTED BY APPLICABLE LAW, USE OF THE ONYX SOFTWARE AND ANY SERVICES PERFORMED BY OR ACCESSED THROUGH THE ONYX SOFTWARE IS AT YOUR SOLE RISK AND THAT THE ENTIRE RISK AS TO SATISFACTORY QUALITY, PERFORMANCE, ACCURACY AND EFFORT IS WITH YOU.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE ONYX SOFTWARE AND SERVICES ARE PROVIDED "AS IS" AND “AS AVAILABLE”, WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND.

TO THE EXTENT NOT PROHIBITED BY APPLICABLE LAW, IN NO EVENT SHALL TITANIUM SOFTWARE BE LIABLE FOR PERSONAL INJURY, OR ANY INCIDENTAL, SPECIAL, INDIRECT OR CONSEQUENTIAL DAMAGES WHATSOEVER, INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF PROFITS, CORRUPTION OR LOSS OF DATA, FAILURE TO TRANSMIT OR RECEIVE ANY DATA OR INFORMATION, BUSINESS INTERRUPTION OR ANY OTHER COMMERCIAL DAMAGES OR LOSSES, ARISING OUT OF OR RELATED TO YOUR USE OR INABILITY TO USE THE ONYX SOFTWARE OR SERVICES OR ANY THIRD PARTY SOFTWARE OR APPLICATIONS IN CONJUNCTION WITH THE ONYX SOFTWARE OR SERVICES, HOWEVER CAUSED.

Requirements

OnyX only works on a Macintosh computer using macOS Catalina 10.15. Using OnyX on a Hackintosh or with a hacked/patched computer is at your sole risk.

Back up your data

Before using OnyX, back up your data.

OnyX is not problem-free, and no user is infallible. Back up your data using Time Machine or any third–party backup utility.

Computer does not respond

OnyX cannot destroy the operating system.

If your computer does not respond during the verification of the disk, you need not worry. This is an expected and normal behavior. This operation can take a very long time to complete (from some minutes to several hours). After OnyX has finished checking, control will be returned to you.

Personal data removed

OnyX doesn't remove your personal data . . .

but you must observe certain basic rules regarding the file system. macOS is a UNIX–based operating system and has a well–defined structure. Your data must be stored in your home folder, in the existing folders (for example, "Documents," "Pictures," and "Music," or in additional folders that you have previously created in your home folder). You should never store your documents or applications in folders that are subordinated to the operating system (for example, folders named "Library," "System," or in any of the subfolders of these folders).

Anybody can make a mistake or handle data incorrectly.

Back up your data regularly.

Problem with a hidden function

OnyX will not always be able to correct a function that has an undesirable behavior.

The functions in the panes of the Parameters toolbar item were created by the developers of the operating system or of the application concerned. OnyX merely turns those functions on or off, using a simple command, at your discretion. If one of those functions causes a problem, turn it off. Do not forget: If a function is hidden, there must be a good reason.

Updates

Always update OnyX, your operating system, and your system software.

The latest versions generally correct at least some of the issues encountered in previous versions.

Uninstall OnyX

To uninstall OnyX, choose Help > Uninstall OnyX. In the confirmation message that appears, click the Continue button. The application and the components created while installing and using OnyX will be removed.
