Configuration settings and preferences of Mac OS X apps are usually stored in a so-called plist (Property List file) file, stored in the folder ~/Library/Preferences. These files store a list of properties in a serialized way, and are binary (not readable/editable).

As no such installer exists, I decided to create my   ...

The tool uses the native Wi-Fi API and uses a current wireless network card, without actually claiming  ...
