PrefEdit is a utility that allows you to inspect and edit all preference settings for OS X applications. The settings are displayed in a browser and can be edited by simple point-and-click operations. You can also do a full-text search on all settings, or clean up unused entries of applications that have been uninstalled.

Features
Browse through the complete list of macOS preference domains, including the preference settings of programs protected by an application sandbox.

You can search for any setting in the database, either by value or by internal name of the preference.
PrefEdit can automatically determine the correct preference domain name for a given application.

You can change any entry in the preferences database or in a property list file. Property names, entry types and values can be edited freely. Entries can be removed or added. The program handles nested entries of any depth correctly.

Entries can be moved or copied within the same or different files, using copy/paste or drag-and-drop.
The application has full undo and redo capabilities with an unlimited number of steps.
The "Versions" feature of macOS can be used to restore old versions of a file you have edited with PrefEdit.
It is shown if certain settings are controlled by the client management (MCX) system of macOS which is used via directory services or Apple Profile Manager in professional networks.

PrefEdit automatically detects if metadata for preference settings are available in a preference manifest provided by the application's vendor. In this case, the exact description of the setting, its meaning, and possible value ranges can be displayed.
Preference domain inspectors allow to view the exact relationship between entries in the live preferences database and their counterparts in the persistent preference files.

The preference search path used by each compliant macOS application can be visualized, showing the effects of overriding settings and reflecting the view on the settings as each application sees them.

Requirements
Intel, 64-bit processor OS X 10.9 or later
