The Unarchiver is a proprietary freeware data decompression utility, which supports more formats than Archive Utility (formerly known as BOMArchiveHelper), the built-in archive unpacker program in macOS. It can also handle filenames in various character encodings, created using operating system versions that use those character encodings.
The Unarchiver 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.
I was sure that the Unarchiver is an in-built Mac app unless it was acquired by MacPaw. The new UI is much better. The Unarchiver can deal with any archives and its performance is impressive.
