PrefEdit Screenshots The following pictures give you an impression on typical work with the application. After launching PrefEdit, the different components (preference domains) of the macOS preferences database will be listed. PrefEdit can automatically find the domain which is responsible to hold the preference settings of a given application. Detail information about preference domains can be shown in an inspector panel. You can search for settings and their names in the entire preferences database of macOS. You can view and change any aspect of the raw preference settings. Another advanced feature of PrefEdit is to visualize macOS's internal search path for preferences. PrefEdit fully supports the Versions feature of macOS.
