Have you ever downloaded a file on your Mac only to realize it’s in RAR format—and macOS won’t open it? You’re not alone. Many users quickly discover that Finder doesn’t natively support RAR archives, which leads to a common question: what is the best Mac software to open RAR files?
RAR files are widely used for compressing and sharing large datasets, software packages, and media files. While they’re common across the internet and business environments, macOS requires third-party tools to handle them. In this guide, we’ll explore the best Mac software to open RAR files, how these tools work, security considerations, and best practices for both personal and enterprise use.
What Is a RAR File?

Be split into multiple parts
Include error recovery data
