CalHash
CalHash is a macOS utility for calculating and comparing file checksums so you can verify file integrity without using Terminal.
What is CalHash?
CalHash is a macOS utility for calculating and comparing a file’s checksum, also called a message digest. It helps Mac users verify that a downloaded, copied, or archived file matches an expected hash value before they use or share it. This makes it useful for software downloads, file integrity checks, and simple verification workflows where you want a graphical tool instead of command-line utilities. CalHash is published by Joel BARRIERE through Titanium Software and is offered in versions matched to major macOS releases. The app fits best for users who want a lightweight checksum checker focused on one task rather than a larger maintenance suite. It is also part of the broader OnyX family of macOS utilities.
Key features
- Calculate a file checksum from a graphical macOS app

Safety overview
Status: Mostly safe
CalHash is a legitimate file verification utility for macOS. Its normal job is to read files you choose so it can calculate their checksums, which is expected for this kind of tool. Removing it does not remove your documents, but you would lose its checksum-checking function until you reinstall it. Use the release intended for your macOS version for the smoothest operation.
Recommendation: Keep CalHash if you use it to verify downloads, archives, or other files by checksum. If you do not use file integrity checks, you can remove it without affecting your personal files or normal macOS use.
