Hi there! I understand you're having trouble updating the Da Fit app and connecting to the internet on your Mac running OS X 10.15.7. To help you better, could you please tell me if the issue happens only with the Da Fit app, or are you unable to connect to the internet on your Mac in general?

Meanwhile, let’s start with some basic checks and fixes for the Da Fit app and internet connection:

1. Check Your Internet Connection:
- Since your Mac is on OS X 10.15.7, please ensure it is connected to Wi-Fi or Ethernet properly.
- Try opening a website in your browser to confirm internet access.

2. Restart Your Mac:
- Sometimes a simple restart can refresh network settings and app processes.

3. Update the Da Fit App:
- Are you using Da Fit via an app downloaded on your Mac or through a browser-based interface?
- If it's an app, try to close the app completely and then reopen it.
- Check if there’s an update available in the Mac App Store.

4. Clear App Cache or Reinstall:
- Since Da Fit app might have cached data causing trouble, uninstall the app and reinstall it fresh.

5. Network Settings:
- Try resetting your Mac's network settings by toggling Wi-Fi off and on.
- Remove and re-add your Wi-Fi network password.

If you’ve already tried these, please let me know exactly what you have done and what happens when you try to update or connect, so I can guide you to more specific steps or deeper troubleshooting.

Looking forward to helping you!
