macOS Notice (Soft Launch)

This version of Startrails Stacker is part of a soft launch.

Due to an Apple-side issue, the app isn’t notarized yet, which may cause a macOS warning. The app is safe to use and is properly code signed with an apple certificate, and this will be resolved in a future update.

Quickest way to open the app (Before doubling clicking the .pkg file)

1. Right-click the app

2. Select Open

3. Click Open again when prompted

You’ll only need to do this once. macOS will remember your choice.

If you already double clicked the .pkg file

1. Double‑click the .pkg

2. macOS says it “can’t be opened because Apple cannot check it”

3. Open System Settings

4. Go to Privacy & Security

5. Scroll down to Security

6. Click Open Anyway next to the Startrails installer

7. Confirm Open
