## Basic Information
Basically, a bundle is a **directory structure** within the file system. Interestingly, by default this directory **looks like a single object in Finder**. 
The **common** frequent bundle we will encounter is the **`.app` bundle**, but many other executables are also packaged as bundles, such as **`.framework`** and **`.systemextension`** or **`.kext`**.
The types of resources contained within a bundle may consist of applications, libraries, images, documentation, header files, etc. All these files are inside `<application>.app/Contents/`
```bash
ls -lR /Applications/Safari.app/Contents
```
*`Contents/_CodeSignature`
Contains **code-signing information** about the application (i.e., hashes, etc.).
*`Contents/MacOS`
Contains the **application’s binary** (which is executed when the user double-clicks the application icon in the UI).
*`Contents/Resources`
Contains **UI elements of the application**, such as images, documents, and nib/xib files (that describe various user interfaces).
*`Contents/Info.plist`\
The application’s main “**configuration file.**” Apple notes that “the system relies on the presence of this file to identify relevant information about \[the] application and any related files”.
* **Plist** **files** contains configuration information. You can find find information about the meaning of they plist keys in [https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Introduction/Introduction.html](https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Introduction/Introduction.html)
* Pairs that may be of interest when analyzing an application include:\\
* **CFBundleExecutable**
Contains the **name of the application’s binary** (found in Contents/MacOS).
* **CFBundleIdentifier**
Contains the application’s bundle identifier (often used by the system to **globally****identify** the application).
* **LSMinimumSystemVersion**
Contains the **oldest****version** of **macOS** that the application is compatible with.
