Hi there! I understand that your Fun Bridge app on your Mac running OS X 10.15.7 keeps freezing, which must make playing quite challenging. Let's work together to get this sorted out.

To start, could you tell me a bit more about when the app freezes? For example, does it happen right after launching, during gameplay, or after performing a specific action? Also, are you connected via WiFi or wired network?

Meanwhile, here are some general steps that often help with freezing issues on Fun Bridge:

1. Restart the App and Device: Quit Fun Bridge completely and then reopen it. Sometimes, a fresh start clears temporary glitches. Also, restart your Mac to refresh its system processes.

2. Update the App: Ensure you are using the latest version of Fun Bridge available for macOS. Updates often include bug fixes that address freezing issues.

3. Check Network Connection: A slow or unstable internet connection can cause the app to freeze. Try switching to a different WiFi network or use Ethernet if possible.

4. Clear App Cache: Sometimes cached data can cause problems. Although Macs don’t typically have a direct cache clear option for apps, reinstalling Fun Bridge essentially clears its data footprint and can help.

5. Close Background Apps: Running many apps simultaneously can strain your Mac's resources. Closing unnecessary apps while playing could improve performance.

If you have already tried these steps, please let me know which ones, and we can dive deeper into other potential causes or settings to adjust. How does that sound?
