Hi there! I see you mentioned "Not working" for the meteoblue Weather & Maps app on your Mac with OS X 10.15.7. I'd like to understand a bit more to help you effectively. Could you tell me exactly what is not working? For example, is the app not loading, are maps not displaying, or is something else happening?

Meanwhile, here are some quick steps we can try to troubleshoot basic issues with meteoblue on your macOS:

1. Refresh the app or webpage — Sometimes simply reloading solves temporary glitches.
2. Clear the browser cache if you are using meteoblue in a web browser. This will remove old files that may interfere.
3. Check your internet connection to make sure it is stable and fast enough to load weather maps.
4. If it’s the app, try closing it completely and reopening; if that fails, uninstalling and reinstalling the app can help resolve deeper problems.
5. Make sure your Mac system and browser (if applicable) are updated, though on macOS 10.15.7 you might be limited to security updates only.

If you have already tried anything like that or if the problem is different, please share more details. For example, any error messages or which exact feature is failing? That way I can guide you better.

Are you using the app or the website? And do you see any specific error or is it just not responding?

Looking forward to your reply!
