The app won't launch or update

If Todebaran won't start, or an update won't apply, work through these steps.

Won't open#

1. Restart your Mac — it clears the most common transient issues.
2. Reopen from Applications — make sure you dragged Todebaran to your Applications folder during installation, and launch it from there rather than the disk image.
3. Check the requirements — Todebaran needs macOS 13 Ventura or later. See Supported platforms.
4. Right-click → Open — if macOS blocks a freshly downloaded app, right-click the app and choose Open once to confirm.

An update won't install#

• Direct download — Todebaran updates automatically. Quit and reopen it to let a pending update apply, or download the latest build fresh from the download page.
• Mac App Store edition — updates come through the App Store app, not Todebaran. Check for updates there.

You can always see the newest version and what changed on the changelog.

Your data is safe#

Reinstalling or updating does not touch your tasks — they live in a separate data folder on your Mac. If you're worried about a bad update, the safest backup is a sync location or a Time Machine backup before you update. See Your data & privacy.

Still stuck?#

Contact support with your macOS version and whether you're on the direct download or the Mac App Store edition.
