The Unarchiver is a free archive decompression utility for macOS. It supports many more formats than macOS's default Archive Utility and is easy to set up and use.

After you install The Unarchiver, right-click an archive file (such as a .ZIP or .RAR file) and select Get Info. Then, in the Open with: section, select The Unarchiver and Change All.... This will set The Unarchiver as your default archive decompression utility.

You can view the types of archives The Unarchiver opens from the app's Preferences menu. From this menu, you can also modify some advanced extraction settings (though you likely will not need to).


The Unarchiver is a big upgrade to Apple Archive Utility. And since The Unarchiver is free (and doesn't show ads), there's no reason every macOS user shouldn't install it.
