Hi there! I understand you're having trouble connecting the myAllergyPal app to its server on your Mac running OS X 10.15.7. Let's see if we can get this sorted out together.

First, can you confirm a couple of things for me? Are you using the myAllergyPal app downloaded from the Apple App Store on your Mac, or are you running it on an iOS device like an iPhone or iPad? Also, is this connection issue happening all the time, or did it start happening recently?

Meanwhile, here are some initial steps you can try to troubleshoot the connection issue:

1. Check Your Internet Connection
Ensure your Mac is connected to the internet with a stable connection. You can open a web page in your browser to confirm.

2. Restart the App
Close myAllergyPal completely and reopen it. Sometimes, this can clear temporary glitches.

3. Restart Your Mac
A simple restart can refresh network settings and system processes.

4. Update the App
Double-check that you are running the latest version of myAllergyPal. On macOS, check the App Store for any available updates and install them.

5. Check for System Updates
Your Mac is running OS X 10.15.7 (Catalina), which is a supported system, but verifying that no further updates are pending can be helpful. Go to Apple Menu → System Preferences → Software Update.

6. Network Permissions
Sometimes firewall or security settings on your Mac can block app connections. Go to System Preferences → Security & Privacy → Firewall, and see if anything could be blocking the app. You might temporarily disable the firewall to test.

7. VPN or Proxy
If you use any VPN or proxy services, try disabling them temporarily, as they can interfere with app-server communication.

If none of these steps work, the issue might be due to server-side problems or account-specific issues. Since myAllergyPal’s support is available at [email protected], we can consider contacting them if needed.

Could you please try these steps and let me know what happens? Also, if you already tried some of these, please share which ones so I can suggest deeper fixes.
