AttacheCase
AttacheCase is a file and directory encryption utility for macOS that allows users to create encrypted containers for sensitive data. It provides a straightforward way to encrypt files and folders with password protection, making it useful for users who need to secure personal documents, financial records, or other confidential information. The app is particularly popular among security-conscious individuals and those handling sensitive business data who want a simple, dedicated encryption tool without relying on full-disk encryption or more complex security suites.

1 suggestionAttacheCase version 4.2.1 (the latest known version) does not appear to have a native Apple Silicon build. The app is available via Homebrew Cask and the official website (hibara.org), but architecture information is not confirmed as Universal Binary or native arm64. The developer (Hibara Software) does not appear to have announced a native Apple Silicon version or provided evidence of active development for modern Mac architectures. Since this is a utility that runs under Rosetta 2, you have two options: (1) Continue using it under Rosetta 2 for now—it will work but with slightly reduced performance; or (2) consider a native alternative. For file encryption on Apple Silicon Macs, consider **Encrypto** (free, lightweight, native) or the built-in **Finder encryption** (create encrypted disk images). Both are actively maintained and fully native to Apple Silicon. If you specifically need AttacheCase's feature set, monitor the official website periodically for updates, but do not expect an Apple Silicon version in the near term.
