Jacksum for macOS is an installation program with which you can easily access functions of Jacksum on macOS. In other words, it adds more than 480 hash algorithms to your Mac and you can use them with different user interfaces to calculate hash values, verify data integrity, and many more. See the Jacksum page for more info.
The installation program installs
- Jacksum which is the hash engine, it also provides the command line interface (CLI)
- HashGarten which is a standalone graphical user interface (GUI) for Jacksum
- script glue to call Jacksum and HashGarten from your preferred file manager

Download the latest .dmg.
Open the .dmg.
With the release of macOS Sequoia, any app from an unidentified developer gives an error that the app is not opened.
Tip
To open any of such apps, open "System Settings", and go to the "Privacy & Security" tab. On the "Privacy & Security" page, scroll down to last. Under the Security section, you have the option to open the application that was previously blocked. Click on the "Open Anyway" button to open it, and proceed with the prompts. Your app will be opened.
To allow open apps on macOS from anywhere, open a Terminal and enter sudo spctl --master-disable. In the Security section, under "Allow applications from", there is a new menu item called "Anywhere.". This will set the behavior as it was in Sonoma and earlier releases of macOS.
To verify the integrity of the app you can compare the hash values that are listed with the release notes for each release. To calculate hash values you can use hash tools such as Jacksum for macOS.
Control-click on the app icon, and choose Open from the shortcut menu. Gatekeeper warns you about the app, but gives you the option to bypass its default policy and open the app.
Tip
You can open a Terminal to bypass both the graphical installation program and security warnings and run the script directly that is bundled with the installer app. Example for Jacksum 3.7.0:
% cd /Volumes/Jacksum\ for\ macOS
% ./Jacksum\ 3.7.0\ for\ macOS.app/Contents/Resources/script
At the end of the task a summary will tell you what file managers have been found and where Jacksum and HashGarten have been integrated.
- Intel Mac (x64) or Apple silicon (aarch64)
- 150 MiB disk space
- macOS 10.11 (El Capitan) or later, tested up to macOS 15.1.1 (Sequoia)
- optional: a supported file manager (see below) to call Jacksum and HashGarten from your flie manager
Finder which supports the Apple Script Menu is fully supported by this integration program. In adddition to that, some file managers providing proprietary interfaces are also supported.
Tip
If your preferred file manager does not support the Apple Script Menu, nor allow to use any external scripts nor support any plug-ins, chances are high that your file manager supports at least drag & drop, so you could use drag & drop to transfer file/directory-paths from your file manager to the HashGarten GUI where you can process data further, e. g. calculate hashes from file/directory-paths.
