The Unarchiver for Mac is the only app you need to open RAR on Mac. It’s times more powerful than the native macOS utility and supports infinitely more archive formats. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip, LhA, StuffIt and many other more or less obscure formats.
