Your archives. His problem.

SweetUn's first downloadable release is a tiny native macOS archiver with a very smug bull handling the paperwork.

Download and install

  • Download SweetUn-0.1.0-universal-local.dmg below.
  • Requires macOS 13 or later; one universal app supports Apple Silicon and Intel.
  • Open the DMG, drag SweetUn into Applications, then launch it from Applications and eject the DMG.
  • No Homebrew or separate engine installation is needed.

Signing: This release uses local ad-hoc signatures for the app and DMG. It is not Developer ID signed or notarized by Apple. A local signature does not establish a verified developer identity. If macOS blocks it and you trust this download, follow Apple's instructions to use System Settings → Privacy & Security → Open Anyway when available. Do not disable Gatekeeper.

What's inside

  • Extract ZIP, 7Z, RAR/RAR5, TAR, and compressed TAR archives.
  • Create ZIP and 7Z with three friendly packing styles.
  • Queue multiple archives; retry failures, pause for passwords, and keep completed outputs.
  • Preview and confirm legacy ZIP filenames in Simplified Chinese, Traditional Chinese, Japanese, Western encodings, or UTF-8.
  • Reject conflicting filenames instead of silently skipping entries.
  • Add compression inputs across multiple drops, inspect the list, and remove individual files.
  • Finder Services → Compress with SweetUn for selected files and folders.
  • Confirm before quitting active or pending tasks; cancel and clean up before exiting.
  • English and Simplified Chinese interfaces, with a native vector bull animation.

Known limits

  • This is an early 0.1.0 release, not a notarized production build.
  • Symbolic/hard links in archives are rejected; compression rejects symbolic links, including nested ones.
  • Legacy filename recovery applies to single-file ZIPs, including standard ZIP64 metadata and tested AES-encrypted entries. Split ZIPs and unusual directory metadata are outside that recovery path. Repair uses a temporary copy and needs extra free space.
  • Filename collision checks are conservative even on case-sensitive disks.
  • Full preservation of macOS resource forks and extended attributes is not verified; this is not a system backup tool.
  • RAR multipart compatibility, very large archives, and installation across other Macs/macOS versions need more testing.
  • Encrypted archive creation is not available.

Verification and licenses

43 automated tests passed. The universal build, code signatures, DMG checksum, mounted contents, and copied application signature were verified locally. This does not replace testing on another Mac.

Download the .sha256 file beside the DMG, then run:

shasum -a 256 -c SweetUn-0.1.0-universal-local.dmg.sha256

SweetUn is MIT licensed. The bundled 7-Zip engine has separate LGPL/BSD/unRAR terms. Licenses and the corresponding 7z2603-src.tar.xz source archive are included in the DMG and attached separately below.
