Can I Uninstall OnyX on Mac Completely?

I no longer need the app OnyX on my Mac, but I feel that dragging the app to the Trash doesn’t clean thoroughly.
What can I do?

You can manually delete OnyX on Mac:

  1. Quit OnyX completely. Finder > Applications > Right-click OnyX and choose Move to Trash.
  2. Finder > Go > Go to Folder > Type the following path and delete the OnyX inside them all:
    ~/Library/Caches, ~/Library/Preferences, ~/Library/Application Support, ~/Library/Saved Application State, ~/Library/LaunchAgents, ~/Library/LaunchDaemons, ~/Library/PreferencePanes, ~/Library/StartupItems

Good luck.
