SevenMac is a native SwiftUI file-manager style front end for the official 7-Zip console engine (7zz), built for macOS 13+ on Apple Silicon (M1/M2/M3/M4). It is modelled on the Windows 7-Zip File Manager / NanaZip workflow - browse, open archives like folders, add, extract, test, checksum, benchmark - instead of the "drop a file and hope" model most Mac archivers use.

Double-click a file inside an archive to view or edit it. Save UTF-8 text with Cmd+S, or use Replace File for binary content. ZIP (including APK), 7z and TAR support editing. SevenMac checks the updated archive before saving and keeps a backup next to the original.

Search finds entries across archive folders. Recent archives are in the sidebar; the header shows whether the format is editable. Right-click a file and choose Open as Archive to try a container with an unfamiliar extension.

The text editor supports UTF-8 files up to 2 MB. This is a container editor: it does not decompile DEX, decode Android binary XML or sign APKs. Modifying signed packages invalidates their signature; see Android signing tools. Documents must retain their own internal schema. Some vendor-specific variants and codecs are not supported by the bundled engine.

On an Apple Silicon Mac with Command Line Tools:

bash scripts/test.sh
bash scripts/build_app.sh
bash scripts/make_dmg.sh

The checks use real temporary archives and the bundled engine; no external test dependencies or full Xcode installation are required. The app build regenerates its icon before packaging.

Push or upload the project contents to main, including .github, Resources, Sources, Tests and scripts. GitHub Actions tests the app, builds the DMG and publishes a new release using the version in Resources/Info.plist and notes in docs/releases/v<version>.md. No personal access token or manual tag is needed. Published versions are left unchanged; increase the version and add matching notes for the next update. You can retry a failed run from the Actions tab. Tag builds remain supported, but the tag must match the app version.

SevenMac brings the familiar 7-Zip file-manager workflow to macOS in a small, open-source SwiftUI app. Browse archives as folders, inspect package contents, edit files and keep control over compression options.

See the roadmap for planned package inspection, archive comparison and Finder integration.

• Browse the filesystem and archives in one window. Double-click an archive to step inside it like a folder; nested folders inside the archive are virtualised from 7zz l -slt output.
• Columns: name, size, packed size, ratio, modified date, kind. Sortable, filterable.
• Add to archive sheet: format (7z/ZIP/TAR/GZIP/BZIP2/XZ/WIM), level Store→Ultra, solid mode, thread count, AES-256 password, encrypt file names (-mhe=on), split volumes (-v100m), delete source after compression (-sdel).
• Extract sheet: destination picker, keep/flatten paths (x vs e), overwrite policy (-aoa/-aos/-aou/-aot), extract only the selection.
• Test integrity (t), remove from archive (d), checksums (h -scrcSHA256), benchmark (b -md=…) with live output.
• Live progress parsed from -bsp1, with Cancel (terminates the child process).
• Encrypted archives: password prompt on open, header-encrypted archives supported. stdin is closed so 7zz can never hang on an invisible prompt.
• Drag & drop onto the window (archive → open, files → compress), Finder reveal, full menu bar with shortcuts, Settings for default format/level and engine path.

1. Download SevenMac.dmg from the latest release.
2. Open the DMG and drag SevenMac into Applications.
3. First launch only: right-click the app → Open (the build is not notarized by Apple, so macOS shows a one-time warning).
