Hi! I understand your Athletics Mania game on your Mac is freezing, and you'd like to get it fixed. To help you better, could you please tell me:

- When exactly does the freezing happen? (e.g., right on startup, during gameplay, at a specific screen)
- Have you tried any steps already to fix it?
- Are you running the game through a web browser or some app version on your Mac?

Meanwhile, I'll suggest some general steps tailored for your Mac with OS X 10.15.7:

1. Restart the Game and Mac
Sometimes just closing the app completely (Cmd+Q) and reopening it can help. Also try restarting your Mac to clear temporary glitches.

2. Clear Browser Cache (if using browser)
If you play it in a browser, clearing your browser cache can resolve freezing caused by corrupted temporary files.

3. Check for Updates
Make sure the game and your browser (or app) are up to date. Updates often fix bugs causing freezes.

4. Close Other Apps
Freezing can happen if system resources are low. Close other apps running to free up memory.

5. Reinstall the Game
If the problem persists, uninstall and reinstall Athletics Mania to replace any corrupted files.

If the freeze occurs specifically when loading a stadium map or certain features, or if the game freezes without crashing and just hangs on a black screen, those are known issues some users have experienced1 8.

Please let me know your scenario in more detail, and we can go through more specific troubleshooting. Also, if there's any error message shown when freezing happens, that info would help.

Are you satisfied with this initial guidance?
