Hello! I see that your Solitaire Cash app keeps crashing during play on your Mac running OS X 10.15.7. That must be interrupting your gameplay quite a bit. To help you out better, could you tell me if the crashes happen right when you start the app, during specific actions or levels, or randomly? Also, have you tried any steps already to fix this?

Meanwhile, I'll walk you through some common steps to stabilize the app:

1. Restart Your Mac: Sometimes a fresh restart clears out temporary issues that can cause crashes.

2. Check for App Updates: Ensure your Solitaire Cash app is updated to the latest version available on the Mac App Store.

3. Close Background Apps: Having many apps open can consume resources. Try closing others to free up memory.

4. Clear App Cache or Data: Although macOS apps may store cache differently, you can look for app-specific cache files in ~/Library/Caches/ related to Solitaire Cash, and carefully delete those.

5. Reinstall the App: If crashes persist, uninstall Solitaire Cash, then download and install it fresh. This can fix corrupted files.

6. Update macOS: You’re on 10.15.7 Catalina. Confirm if any minor updates are pending in System Preferences > Software Update.

7. Check Your Internet Connection: Solitaire Cash needs a stable online connection. Verify your Wi-Fi or Ethernet is stable.

If you’ve tried some of these already or if crashes occur at specific moments, please let me know. I can then suggest more targeted fixes.

Are you comfortable going through these? I’m here to guide you at every step!
