PrefEdit for Mac是一款Plist文件和Mac系统相关文件的编辑工具，用于管理每个macOS安装中包含的偏好系统的几乎所有方面。该方案由三个相互紧密结合的组件组成：
首选项清单文件包含所谓的“托管首选项”的说明。如果修改用户偏好设置不仅对于拥有此设置的应用程序感兴趣，而且对于“外来”应用程序也可以访问该设置，则应用程序的供应商可以正式发布关于这些偏好的技术细节。这样的描述指定了哪个名称对应用程序具有哪些含义。另外，可以定义可能的取值范围，以及每个单值的含义。 Apple的Workgroup Manager应用程序使用清单文件来呈现这种可远程管理的设置。
PrefEdit是有史以来为Mac OS X发布的首选编辑器。凭借其丰富的经验和成熟度，它已经成为当今最先进的macOS偏好管理应用程序之一。
PrefEdit is an application to manage nearly all aspects of the preference system contained in every macOS installation. The program consists of three components which are tightly integrated with each other:
- An entry point to the preferences database of macOS, with access to all settings which are effective for your user account
- a browser and editor for macOS property list files (plists),
- a browser for preference manifest files.
Property list files are the technical means used by macOS to store user preference settings in the background. This file type is also utilized by macOS for many other purposes, not only for building the preference database. You can use PrefEdit to display and edit all files compliant with Apple’s plist standard.
Preference manifest files contain descriptions for so-called Managed Preferences. If modifying a user preference setting is not only of interest for the application owning this setting, but access to the setting should be possible for “foreign” applications, too, the vendor of the application can publish technical details about these preferences formally. Such a description specifies which setting with what name has which meaning for an application. In addition, the possible value range, as well as the meaning of each single value can be defined. Apple’s Workgroup Manager application uses manifest files to present such remotely manageable settings.
PrefEdit is directed both to software developers and to end users who like to have full access to each and every aspect of preference settings for the system and applications. The program is capable of visualizing the complete search path and priority of user default settings, exactly imitating the view each macOS application has on the preferences database.
PrefEdit was the first preference 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 macOS available today.
