ELI5: Explain Like I'm 5

Bundle (OS X)

A bundle on macOS is like a fancy, special folder that holds a bunch of important files that a program needs to run. Think of it like a lunchbox that holds all your favorite snacks, but for your computer program.

Inside this lunchbox-bundle, there are different compartments for different types of files, like pictures, sounds, and instructions. When you want to use the program, the computer knows to look inside the lunchbox-bundle and grab all the important files it needs to start up.

And just like with your lunchbox, it's important to keep everything organized and in the right place, so the computer knows which file goes where. This helps the program run smoothly and perform all the cool things it was designed to do.
