Hi there! I understand you’re having trouble with the FOX LOCAL app not opening or loading on your Mac running OS X 10.15.7. Let's work through this together. Could you tell me a bit more about what exactly happens when you try to open the app? For example, does it crash immediately, show a loading screen and then nothing, or something else?

In the meantime, here are some steps we can try to get the app working again:

1. Restart Your Mac: Sometimes a simple restart clears temporary glitches that might be blocking the app.

2. Check Internet Connection: Make sure your Mac is connected to a stable internet—try loading a webpage to confirm.

3. Update the App: Since you’re on a Mac, check the App Store for any available FOX LOCAL app updates. Running an outdated version can cause load failures.

4. Clear App Cache: Although Macs don’t have a simple "clear cache" button like phones, you can try deleting the app’s cache files if possible. You’d typically find these in the ~/Library/Caches folder related to the app. I can guide you through this if you'd like.

5. Reinstall the App: If updating doesn’t help, try uninstalling FOX LOCAL and reinstalling it fresh from the App Store.

6. Check for System Updates: Ensure your macOS is fully updated; sometimes, app compatibility depends on system updates.

If you’ve already tried any of these, please let me know which ones so I avoid repeating them. Also, if you see any error messages, sharing those will help pinpoint the issue.

Does this sound okay to start with?
