Download of Prefling 2.1.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. This free Mac app is a product of Amar Sagoo. Prefling for Mac is included in System Tools.
From the developer:
Prefling does one job: It lets you open system preference panes. Fast. Sitting in your Dock, it shows you a menu with all the preference panes installed and active. It's the ideal replacement for the "System Preferences" item that's in your Dock by default.
