Security Verification
SHA-256 Checksum on GitHub Releases

CastSprint is 100% free forever with no accounts, paywalls, watermarks, or analytics tracking. Always download official releases from the verified repository and verify the SHA-256 checksums before running installer binaries.

Verifying Release Artifacts

Compare the SHA-256 hash of your downloaded file against the official hash published in the release notes:

macOS / Linux Checksum
shasum -a 256 CastSprint-macOS.dmg
Windows PowerShell Checksum
Get-FileHash .\\CastSprint-Windows-x64.zip -Algorithm SHA256

macOS Installation & Gatekeeper

  2. Double-click the DMG to open it.
  3. Drag CastSprint to your Applications folder.
  4. Eject the disk image.
  5. Launch CastSprint from Applications.
Gatekeeper FAQ

Public distribution requires Apple Developer ID signing and notarization. If macOS displays a warning for a non-notarized community build, review System Settings > Privacy & Security and click Open Anyway only after verifying the SHA-256 checksum against the official GitHub release.

Windows Installation

  1. Download CastSprint-Windows-x64.zip.
  2. Extract the archive into a folder of your choice (e.g. C:\Tools\CastSprint).
  3. Ensure Microsoft Visual C++ 2022 Redistributables (x64) are installed.
  4. Run castsprint_receiver.exe.
  5. When Windows Defender Firewall prompts on first launch, check Private networks and click Allow access.
