Are you a Mac user staring at a .rar file that just won’t open?
You are not alone. Unlike Windows, macOS does not have built-in support for RAR files. If you double-click it, nothing happens, or you get an error message saying there is no application to open the document.
In the past, you had to go to the App Store, search for “The Unarchiver” or “Keka,” install it, and clutter your Mac just to open one single file.
But in 2025, there is a better way. You don’t need to install anything.
