StuffIt 16
StuffIt is a file archive and compression utility for macOS that creates and extracts compressed archives in formats including .sit, .zip, .rar, .7z, .tar and others. Historically one of the most widely used compression tools on Mac before the rise of built-in zip support and third-party alternatives, StuffIt served home users, IT professionals, and software distributors who needed reliable compression and decompression. The app includes archive browsing, splitting large archives, password protection, and batch operations.
AI Recommendation
1 suggestionStuffIt has been discontinued by its developer and is no longer receiving updates. The app will not launch on macOS 28 (September 2028) when Apple removes Rosetta 2 support for Intel-only apps, since no native Apple Silicon build has been released. For anyone still relying on StuffIt, you should transition to an actively maintained alternative now. The Mac's built-in Archive Utility handles standard .zip files at no cost, and for more advanced compression formats, consider free options like The Unarchiver (which runs natively on Apple Silicon and supports a wide range of formats including .sit, .rar, .7z, and .tar) or BetterZip if you need a feature-rich paid tool with a polished interface. Both alternatives run natively on M-series Macs and will remain compatible with future macOS releases.
