Download verification

Match the complete ZIP to its published SHA-256 checksum before extracting it. These records apply to the named version only.

Verify the file you received

On macOS, run shasum -a 256 /path/to/package.zip. On Linux use sha256sum; on Windows use PowerShell Get-FileHash -Algorithm SHA256. Compare all 64 characters, not just the filename.

The separate publisher seal authenticates the ZIP with our Apple Developer ID certificate. It contains a public certificate and signature, not a private signing key.

On macOS, download the matching seal and verify it against the original ZIP:

codesign --verify --strict --detached /path/to/package.zip.sig \
  -R '=anchor apple generic and certificate leaf[subject.OU] = "SV5QCS5GZ2"' \
  /path/to/package.zip

Browser HTML and JavaScript packages are not native Mac applications. A publisher seal is not Apple notarization, App Store review or approval of the software's functionality. Private operator apps are not included here.

Contact support if a hash or signature does not match. Do not use the mismatching package.
