PrefEdit is an application to manage nearly all aspects of the preference system contained in every Mac OS X installation. It is directed both to software developers and to end users who like to have full access to each and every aspect of preference settings. It is capable of visualizing the complete search path and priority of user default settings, exactly imitating the view each Mac OS X application has on the preferences database.

The program consists of three components which are tightly integrated with each other:
• A browser and editor for the Mac OS X preferences database,
• a browser and editor for Mac OS X property list files (plists),
• a browser for preference manifest files.

PrefEdit was the first preferences editor ever published for Mac OS X. With its long experience and maturity, it has become one of the most advanced preference management applications for Mac OS X available today. In contrast to other applications, PrefEdit can correctly differentiate between the “live“ view on the preferences dataset as it is currently seen by applications, and the persistent representation of settings in preference files..

Limitations: You can download the application PrefEdit at no charge. This allows you to evaluate the software to see if it suits your needs. During the test phase, only the following restrictions apply:
• A window with the note Running in Demo Mode appears each time the application is started.
• You cannot save changes to the preferences database or to a property list file if your dataset has more than five (5) entries at its top-level.

Requirements:
macOS 10.12+
64-bit Intel
