Download HelloNotes

Installing

1. Download HelloNotes.dmg and open it — a disk image window appears.
2. Drag the HelloNotes icon onto the Applications folder shown beside it.
3. Eject the disk image, then open HelloNotes from Applications or Launchpad.
4. On first launch, choose Open… and pick any folder of Markdown files — or an empty folder to start fresh.

Because the app is signed with a Developer ID and notarised by Apple, macOS opens it without a security warning. You do not need to change any Gatekeeper settings, and you should never need to right-click → Open.

Verifying the download

Every release is code-signed and notarised, so macOS checks it for you. If you would like to verify independently, compare the checksum:

shasum -a 256 ~/Downloads/HelloNotes.dmg

It should print:

cb72851b5b951f454ce31162d43e45ec267990562a6a88eae10e141e82ad44a0

You can also confirm the signature and notarisation with:

spctl --assess -t open --context context:primary-signature -v ~/Downloads/HelloNotes.dmg

which should report accepted and source=Notarized Developer ID.

Updating and uninstalling

To update, download the latest disk image and replace the app in Applications. Your notes are untouched — they are your own files, in your own folder, and HelloNotes never moves them.

To uninstall, drag HelloNotes from Applications to the Trash. Your notes stay exactly where they are. Preferences live in ~/Library/Containers/com.hellotham.HelloNotes if you want to remove those too.

Building from source

HelloNotes is open source. You can read the code, build it yourself, or open an issue on GitHub.
