Hi! I see you're having trouble with the Sleep Number app not responding on your Mac running OS X 10.15.7. I'd be happy to help you get that sorted out. First, can you tell me a bit more about what happens when you try to use the app? For example, does it freeze completely, fail to open, or do you see any error messages?

While I wait for your details, here are some straightforward steps we can try to fix the issue:

1. Restart the App: Close the Sleep Number app completely and then open it again. On a Mac, you can right-click the app icon in your Dock and choose "Quit," then open it anew.

2. Restart Your Mac: Sometimes a simple reboot clears up any temporary glitches affecting app responsiveness.

3. Check for App Updates: Make sure your Sleep Number app is updated to the latest version available. Since your Mac is running an older OS version, also check that the app supports OS X 10.15.7.

4. Reinstall the App: If the app is updated but still non-responsive, try deleting the app and reinstalling it from the official source. This can resolve corrupted files affecting performance.

5. Power Cycle Your Sleep Number Bed (if applicable): Unplug your bed from the power outlet for about 60 seconds, then plug it back in. Allow it 2-3 minutes to reboot before reconnecting with the app. This can help reset the connection[https://support.sleepnumber.com/hc/en-us/articles/360009067613-Trouble-Getting-Online].

6. Check Internet Connection: Ensure your Mac is connected to a stable Wi-Fi network, as the app needs internet access to communicate with your bed and servers.

If you’ve tried any of these already or if the issue persists, just let me know what’s been done so far or any specific error messages you see. That way, I can guide you with more tailored steps or check for other solutions.

Are you able to try these initial steps and share what you observe?
