Hi there! I see you’re having trouble with Real Racing 3 crashing right at startup on your Mac running OS X 10.15.7. Let’s work together to get this sorted out.

First, just to clarify, are you running Real Racing 3 through an emulator since it's primarily a mobile game? Or are you using some other method or platform to play it? Also, did the crashes start happening after any recent changes like an update to the game, the operating system, or any new software installed on your Mac?

In the meantime, here are some general steps you can try to resolve the startup crash issue:

1. Restart your Mac: Sometimes, a fresh reboot clears temporary glitches in the system memory.

2. Clear any saved state or temporary files related to the game: Since this isn’t a native Mac app, how you do this depends on how you’re running it. For example, if you use an emulator, try deleting the saved game cache or resetting the app data.

3. Check for any updates: Make sure your emulator and Real Racing 3 app are updated to the latest versions.

4. Check network connectivity: Real Racing 3 relies on online features, so ensure your internet connection is stable.

5. Reinstall the game: Back up any saved data if possible (like cloud saves), delete the app, then reinstall it fresh.

If you let me know exactly how you’re running the game on your Mac, I can tailor these instructions more precisely. Also, if you’ve already tried any of these steps, please share what you’ve done so we don’t repeat.

Does that sound good? Let me know, and we’ll proceed from there!
