Troubleshooting

"App is damaged and can't be opened"

Because this app is not yet signed with an Apple Developer Certificate, macOS Gatekeeper will block it when downloaded from the internet.

To fix this:

1. Open Terminal.
2. Run the following command (replace path with actual location):

   xattr -cr /Applications/StockTicker.app

3. Open the app again.
