Hi there! I understand that you're having trouble loading the US weather map on WeatherBug after upgrading your Mac to Sequoia. It's possible that the recent update might be contributing to the issue. Let's explore a few steps that might help you resolve it.

1. Check Location Permissions: Sometimes, after updates, permissions may change:
- Go to System Preferences > Security & Privacy > Privacy tab.
- Click on Location Services.
- Ensure that WeatherBug (or the relevant app) is allowed to access your location.

2. Restart WeatherBug: Close the WeatherBug app completely and restart it. This can sometimes refresh the app's connection to the necessary services.

3. Update WeatherBug: Make sure that you have the latest version of WeatherBug installed. You can check for updates in the App Store.

4. Clear Cache and Cookies (if using a browser): If you're accessing WeatherBug online, clearing your browser's cookies and cache can help:
- Open Safari, go to Safari menu > Preferences > Privacy, and click on Manage Website Data. From there, you can remove all data or just specific entries.

5. Test on Different Network: If possible, try connecting to a different Wi-Fi network to check if there is an issue with your current connection.

6. Check for Reported Issues: Given that you’re on a newer version, there could be broader issues affecting users. Reviewing discussions in communities such as the Apple Support Community may reveal if others face similar problems. For instance, reports mention that after the upgrade to macOS Sequoia, location-based services have faced issues1.

If you've tried all these steps and the issue persists, it may be worth contacting WeatherBug support at [email protected] or [email protected] for more tailored assistance.

Are you satisfied with the solutions I provided, or is there something else we can go over?
