If you want to verify the checksum of the BitBoxApp found in our download page, you will need to keep in mind:

• Verification of the checksum has to happen before uncompressing/unzipping the downloaded zip file.
• If on Mac and using Safari: deactivate the auto-decompress zip files feature in your browser settings.

Assuming the current BitBoxApp version is 4.27.0, open a terminal session and type shasum -a 256 BitBox-4.27.0-macOS.zip if the file is in the current terminal directory, or shasum -a 256 /path/to/BitBox-4.27.0-macOS.zip if the working directory of terminal session is different.
