Hi there! I see you’re having trouble with the 2248 game frequently freezing on your Mac running OS X 10.15.7. I’d love to help you get this smoothed out.

Could you tell me a bit more about when the freezing happens? For example:
- Does it freeze during a specific action or at random times?
- Have you noticed if it happens more when you’re low on memory or network connection?
- Have you tried any fixes already?

Meanwhile, here’s a gentle step-by-step approach we can start with:

1. Restart the Game and Your Mac: Sometimes a fresh start clears temporary glitches. Quit the game completely, then restart your Mac.

2. Check for Game Updates: Make sure the 2248 app is updated to the latest version from the App Store, as updates often fix bugs.

3. Free Up System Resources: Close other apps you aren’t using to free up memory and processing power, since freezing can happen when the system is overloaded.

4. Reinstall the Game: If the above don’t help, uninstall the game completely, restart your Mac, and then reinstall it from the App Store. This can clear corrupted files causing freezing.

5. Check Internet Connection (if the game uses online features): Make sure your network is stable.

If after these you still face freezing, we can try deeper troubleshooting, like checking app cache or any configuration settings, or I can help you contact the support team of the game developer.

Does this sound like a good place to start? And please let me know about the freezing details, so I can tailor the help better for your setup!
