Hi there! I understand that your WJTV Weather app on your Mac is showing the wrong map location. Let’s see if we can get that corrected for you. To start, can you tell me if your app is set to use your current location automatically, or if you have manually selected a location within the app? Also, have you tried any steps already to fix this?

Meanwhile, here are some straightforward steps you can try to fix incorrect location issues in weather apps on your Mac OS X 10.15.7:

1. Enable Location Services:
- Click the Apple menu > System Preferences > Security & Privacy > Privacy tab.
- Select Location Services.
- Ensure "Enable Location Services" is checked.
- Also, make sure the WJTV Weather app (if it shows in the list) has permission to access Location Services.

2. Check Internet Connection:
- A reliable internet connection is necessary to pinpoint your location accurately.
- Make sure your Mac is connected to Wi-Fi or an Ethernet network without restrictions.

3. Refresh or Restart the App:
- Close the app completely and reopen it to force it to fetch the correct location again.

4. Manual Location Adjustment:
- If the app allows adding or setting custom locations, try removing incorrect locations and adding your correct one manually.

5. Update the App:
- Ensure you have the latest version of the WJTV Weather app installed. Sometimes, bugs affecting location detection are fixed in updates.

6. System Date & Time Settings:
- Go to System Preferences > Date & Time.
- Verify that "Set date and time automatically" is enabled. Incorrect time settings can sometimes impact location detection services.

If after these steps the issue persists, it might be related to cached data or a deeper app configuration problem. In that case, uninstalling the app and reinstalling it could help.

Do any of these steps sound like something you’ve tried already? Or can you give more details on how the wrong location appears—like is it always a particular place or random? That will help me guide you further!
