How to Convert plist Files to XML or Binary in Mac OS X
Plist files contain preference specifics and properties relevant to a particular application or portion of Mac OS X system software. Depending on where the plist file is located and what function they serve, they can either be in XML format, binary format, and sometimes even json. For users who need to modify a plist file or convert the file format to or from XML and binary, you can do so easily in the OS X Terminal with the help of the plutil command.
