CalHash1.5.8

CalHash calculates a file’s checksum, also known as a message digest, and compares it with another checksum value. This gives Mac users a direct way to evaluate a file against a known digest or compare results produced from the same file. Its focused workflow centers on generating and matching these values.

The utility is intended for Mac computers and is distributed as freeware. It runs on Apple Silicon Macs using macOS 11 Big Sur or newer, corresponding to the arm64 architecture. The developer maintains a separate CalHash build for each major macOS release, so the version must match the operating system rather than being treated as interchangeable. The version map pairs 1.1.1 with Big Sur, 1.1.9 with Monterey, 1.2.1 with Ventura, 1.3.4 with Sonoma, 1.4.6 with Sequoia, and 1.5.8 with Tahoe 26; an older 1.0.5 build is listed for Catalina 10.15.

CalHash suits anyone who needs to calculate a digest and compare it with a supplied or separately calculated value, including routine file verification tasks.
