Hi there! I see you're having trouble downloading Country Star from the App Store on your Mac running OS X 10.15.7. Let's figure this out together.

First, just to clarify, are you searching for the Country Star app directly in the App Store but it doesn’t show up, or does it show up but doesn’t download? Also, have you checked whether Country Star is available in your region or country in the App Store? Sometimes apps are region-locked or removed.

Based on some recent info I found, it looks like Country Star and its related app BeatStar are shutting down soon, which means the app might have been removed from the App Store completely or made unavailable in certain regions5. This could be why you can’t download it.

If you had previously downloaded Country Star on this Apple ID, you might still be able to re-download it from your Purchased list in the App Store, even if it’s not broadly available. You can check Purchased apps by clicking on your account icon in the App Store and then 'Purchased'.

Can you please check both of the following:

1. Search your Purchased apps for Country Star and see if you can download it from there.
2. Confirm your Apple ID region and let me know what country it's set to.

If the app is completely removed or you never downloaded it before, you might not be able to get it from the store anymore.

I’m here to help you through this, so just let me know how these checks go!
