Utilities, Maintenance, Optimization

OnyX is a popular freeware utility for macOS developed by French developer Joël Barrière that 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 macOS, including setting hidden preferences otherwise modified by using property list editors and the command line.

    • Development

    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 macOS's standard Unix utilities, allowing their control through a graphical user interface without needing the command line. OnyX is freeware.
