shasum has no output, why?
Here's the terminal command and output:
douglas@machine Desktop % shasum -a 256 /Users/douglas/Desktop/TinkerTool.app
shasum: /Users/douglas/Desktop/TinkerTool.app:
which shasum:
/usr/bin/shasum
Tinkertool.app is just a folder. You need to run it on the actual app. Your command should be shasum -a 256 /Users/douglas/Desktop/TinkerTool.app/Contents/MacOS/Tinkertool
You can get to the actual app by right-clicking on Tinkertool.app and selecting "Show package contents" and navigating to the actual app.
