Hi! I see you're having trouble with the 77 WABC app on your Macintosh running OS X 10.15.7. To get a better idea of the problem, could you tell me what exactly happens when you try to use the app? For example, does it fail to open, crash, not play the stream, or show error messages?

In the meantime, here’s a general step-by-step approach to start troubleshooting:

1. Restart the app: Completely quit the 77 WABC app and reopen it.
2. Check for updates: Make sure the 77 WABC app is updated to the latest version available on the Mac App Store.
3. Internet connection: Confirm your Mac has a stable internet connection by visiting a few websites in your browser.
4. Clear cache and data: Although more common on mobile, you can try clearing any stored data or preferences related to the app if that option exists on your Mac.
5. Reinstall the app: If difficulties persist, uninstall the 77 WABC app from your Mac and then download and install it again fresh from the Mac App Store.

If you've already tried some of these or get stuck at any step, let me know what you’ve done and what behavior you observed. That way, I can guide you further with more specific fixes.

Are you ready to try this now?
