PrefEdit 5.1

PrefEdit 5.1

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.

PrefEdit can access all preference settings of "well-behaved" Carbon and Cocoa applications. Older Mac applications running in the Classic environment used a totally different system for storing preference settings. The settings of such programs do not appear in PrefEdit.

Warning: If you edit, add, or delete preference values of application programs or the OS X operating system, you should know what you are doing. Inappropriate values can cause serious malfunctions in the system, which could destroy important data or create other unexpected effects.

What's New:
