Tellnova v1.1.9 alpha

Installing

Linux: download the .AppImage, chmod +x it, run it.
Windows: download the -win-x64.zip, extract it, and run Tellnova.exe. SmartScreen may warn — choose More info → Run anyway.
macOS: see below — one extra step is required.

macOS: "Tellnova is damaged and can't be opened"

This build is not yet notarized by Apple (no Apple Developer account yet),
so Gatekeeper shows a scary-but-wrong "damaged" message on first launch. The
download is fine. To open it:

1. Drag Tellnova from the DMG into Applications.

2. In Terminal, run:

   xattr -cr /Applications/Tellnova.app

3. Still blocked on Apple Silicon? Add a local ad-hoc signature:

   codesign --force --deep --sign - /Applications/Tellnova.app

4. Launch normally. This is a one-time step per fresh install.

No Terminal? After one blocked launch attempt, go to
System Settings → Privacy & Security and click Open Anyway.

xattr -cr only removes macOS's download-quarantine flag; it does not modify
the app. You can verify your download against the platform-specific
SHA256SUMS-*.txt file attached below:

shasum -a 256 ~/Downloads/Tellnova-*.dmg

Signed and notarized macOS builds are on the roadmap.
