OnyX · legacy macOS compatibility
OnyX is a widely used macOS system utility included for legacy macOS compatibility tracking.
Only sourced records are listed. A download link is shown only when an official or open-source release URL can be tied to that exact version. An unlisted OS does not automatically mean the app cannot run.
Choose macOS manually when detection is unavailable.
