  • Easily set up and use the program as a replacement for Mac Archive Utility

Software Overview

The Unarchiver is a free data decompression program for Mac that supports many different compressed formats. It was developed to be a replacement to the built-in Mac Archive Utility that doesn't support many formats.

The Unarchiver is designed to be easy to set up and use. After installing it all you have to do is set it as your default program for archive files (which can be done from easily within the program). It is also designed to flow better with the layout of Finder to help give you a more consistent computing experience.

The Unarchiver is a large step up from Mac Archive Utility. If you are looking for a free alternative for compressing and decompressing files and archives on the Mac, it is a great option.
