FileHasher for macOS 1.0.1 is now live on the Mac App Store, and it brings the two upgrades I most wanted to ship since launch: the app is now a universal binary, and it finally has real, built-in help.
Native on Apple Silicon
Version 1.0.0 shipped as an Intel-only build, which Apple Silicon Macs ran through Rosetta 2. It worked, but translated is not the same as native. As of 1.0.1, FileHasher is a universal app: one download, two architectures, each running natively. Before release, the same build was tested natively on both an Apple Silicon Mac and an Intel Mac, with the full engine test suite passing on each; hashing gives you no room to be approximately correct.
Built-in help
The Help menu used to produce the stock “help isn’t available” message, which always bothered me. It now opens a proper help window (also reachable with Cmd-?) with topics covering everything the app does: choosing targets, folder scan options, the four hash algorithms, sidecar formats and conflict handling, verification verdicts, CSV export, logs, and how the app’s privacy and sandboxing work.
One small touch I like: the Email Support link in the help window pre-fills the subject line with the exact app version you are running, read from the app itself at runtime. Every support email arrives self-identified, and the mechanism can never drift out of date between releases.
Where to get it
FileHasher is free on the Mac App Store (macOS 13 or later). If you are new to it: the app computes cryptographic hashes for files and folders, writes standard sidecar checksum files next to them, and verifies everything later, so you can prove a download or archive has not changed since you hashed it. More on the FileHasher page, including the Windows sibling it descends from.
If you try it and something feels off, the help window’s Support topic knows how to reach me.
