Developer's Description

PrefEdit is an application to manage nearly all aspects of the preference system contained in every Mac OS X installation. 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), and 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.

Full Specifications

What's new in version 4.4

  • When saving property list files in XML format, this version enforces more rigorous syntax rules regarding values that contain invalid control characters. This policy is stricter than the policy currently implemented by Apple in macOS, but ensures that files remain compliant with the XML standards. When reading files, PrefEdit uses the same guidelines as macOS. XML files with slight errors will be silently accepted if macOS also tolerates them.
  • Property list files can now still be modified and saved in cases where macOS has lost their type information, e.g. after restoring a file without file extension via the Versions feature.
