If a macOS installer can't be used on your Mac, the installer will let you know. For example, it might say that your Mac doesn't have enough free storage space for the installation, or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, learn about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan, or Yosemite. You can also check compatible operating systems on the product-ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini, or Mac Pro.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar, or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

OnyX is a popular[2]freewareutility 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.[3]

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