PrefEdit lets you inspect and edit preference settings for Mac OS X applications.
The settings display in a browser, and you edit them using the point-and-click method. In addition, full-text search is available on the settings, and you can clean up left overs from uninstalled applications.
For more detailed information, including on updates, please read the documentation or visit the home page.
If you edit, add or delete preference values of application programs or the Mac OS X operating system, you should know what you are doing. Inappropriate values can cause serious malfunctions in the system that could destroy important data or create other unexpected effects.
