Hi there! I understand you're experiencing timing-out issues with the Newsmax app broadcast on your Mac running OS X 10.15.7. To help you best, could you tell me a bit more about your situation? For example:

- Are you watching the live broadcast or on-demand content when it times out?
- Is the app itself crashing or freezing, or is it more like the video stops and buffers repeatedly?
- Have you noticed if this happens on other devices or only on your Mac?
- Have you tried any troubleshooting so far, like restarting the app or your device?

This info will help me guide you through the best steps. Meanwhile, here are some initial steps we can try to address the timing-out:

1. Check Your Internet Connection: A stable and reasonably fast connection is vital. Since you're on a Mac, try opening other streaming sites or apps to see if they also have buffering or timeout problems. If yes, restart your router and modem.

2. Quit and Restart the Newsmax App or Browser: If using the Newsmax app on Mac (or via a web browser), closing and reopening it can clear temporary glitches.

3. Clear Browser Cache (If using a browser): Sometimes accumulated cache can cause streaming issues. In Safari, go to Safari > Preferences > Privacy > Manage Website Data > Remove all.

4. Update Your Browser or App: Ensure your browser or Newsmax app is updated to the latest version compatible with macOS 10.15.7.

5. Restart Your Mac: A simple restart often resolves background glitches affecting streaming.

If the problem persists, we can try more advanced troubleshooting like checking for any firewall or security software interference, or reinstalling the app if applicable.

Does any of this align with what you've tried so far? Let me know, and we can proceed from there!
