Mac computers are great, but sometimes they don’t open certain files right away. Have you ever downloaded a file and it looked like a box with a zipper? That’s a compressed file. To open it, you need a tool like The Unarchiver.
What is The Unarchiver?
The Unarchiver is a free app for Mac. It helps you open compressed files. Think of it like a magic key that unlocks different kinds of packed files. The built-in Mac app only supports a few formats, but The Unarchiver can handle a lot more.
