open 7z file mac So you’ve come across a .7z file and you’re on a Mac, what is it and how do you use it? First off, a .7z file is an archive format that stands for 7-zip, you can think of it like any other archive file. By default, Mac OS X does not know how to handle these files, but that’s not a big deal because there’s a freely available app that will open the .7z file for you.

Open a .7z file in Mac OS X

Follow these steps to open and decompress .7z files:

  • First you need to download Unarchiver (it’s free)
  • Launch Unarchiver and you’ll see a file association list, tell Unarchiver to associate with .7z files (you can select others if you wish)
  • Once Unarchiver is associated with the .7z you can then double-click any .7z file on your Mac and it will open and uncompress like any other archive format

That’s all there is to it, now you’ll always be able to open the .7z archive files on your Mac. Unarchiver is a pretty popular solution to open all sorts of archive formats, it has been discussed here before as an alternate when you need to open and unrar RAR files in Mac OS X as well. Because of it’s flexibility, it’s a good addition to any Mac software toolkit.
