Lumo Copilot v0.2.3 — fixes "damaged" error
Lumo Copilot v0.2.3 — fixes "Lumo Copilot is damaged and can't be opened".
If you hit that error, this release fixes it. Nothing was wrong with your
download — every build before this one shipped with a broken code signature, and
macOS refuses those outright on Apple Silicon with a misleading "damaged"
message. The app bundle is now correctly signed, so it opens normally.
(Cause, for the curious: the project folder is synced by iCloud, which stamps
every file with extended attributes. Those quietly corrupted the signature at
build time. Builds are now signed in a clean location.)
Opening it the first time (macOS 15 and newer)
Apple removed the old right-click → Open shortcut. Now:
- Double-click the app — macOS will refuse it.
- Open System Settings → Privacy & Security, scroll to Security.
- Click Open Anyway next to the Lumo Copilot message, then confirm.
You only do this once. If you'd rather use the terminal:
xattr -dr com.apple.quarantine "/Applications/Lumo Copilot.app"
This is the trade-off of a free, unsigned app — Apple charges for the
certificate that removes the prompt.
Everything else is unchanged from v0.2.2.
