Developed by French developer Joël Barrière, OnyX is a popular[1] freeware utility for Mac OS X and is compatible with both PowerPC and Intel processors. As a multifunctional tool for maintenance and optimization, it can control many basic Unix programs already built into OS X, including setting hidden preferences otherwise modified by using property list editors and the command line.[2] It has become a highly praised utility among many users in the Mac community, in part due to its extensive language support and excellent help files.

Created in 2003 by Joël Barrière, a.k.a. Titanium, the program was originally meant to address its creator's personal needs. Developed using Xcode, Apple's software development environment (Cocoa + AppleScript Studio + Objective-C), OnyX is regularly updated by its author taking into consideration users' suggestions and requests. To do its job, the program uses OS X's standard Unix utilities, allowing their control through a graphical user interface without needing the command line. OnyX is freeware.


OnyX versions are specific to each version of Mac OS X and are not backward compatible. The program will not work correctly if used with an OS for which it was not designed.

Only the Snow Leopard and Lion builds are actively maintained. However, all previous versions in support of past operating systems are still available for download from the developer's website.[3]
