About
The Unarchiver is a free macOS application that extracts files from a wide range of archive formats, including ZIP, RAR, 7z, Tar, and many legacy and unusual formats. It is more capable than the built-in macOS archiving utility and supports non-Latin filenames. The app is free with no in-app purchases and works on macOS 10.13 or later.
Problem
macOS's built-in archive utility supports only a limited number of formats, leaving users unable to open many common archive types like RAR or 7z.
For
Mac users who need to open and extract compressed archive files
How it works
Users set The Unarchiver as the default app for archive files, then simply open any supported archive to extract its contents in seconds.
