Hi there! I’m sorry to hear that your MAPS.ME app keeps crashing on your Mac. Let’s try to get this sorted out together.

To start, could you tell me a bit more about when the crashes happen? For example:
- Does it crash right when you open the app, or while you’re using it?
- Have you noticed if it crashes after performing a particular action (like searching, downloading maps, or using navigation)?
- Have you updated the app recently or your MacOS?

In the meantime, I can suggest some initial steps to try:

1. Restart your Mac: Sometimes a simple reboot clears up temporary issues.

2. Update MAPS.ME app: Make sure you have the latest version installed from the official source (App Store or the developer’s website).

3. Clear app cache and data for MAPS.ME:
- Since you’re on Mac, apps don’t usually have an obvious way to clear cache, but you can try quitting the app completely. Then, you might check the ~/Library folder for MAPS.ME related cache files and move them to Trash.
- To do this: Open Finder, press Command + Shift + G to open "Go to folder," type ~/Library/Caches/ and look for any folder related to MAPS.ME and delete or move it.

4. Check for macOS updates: You are on OS X 10.15.7 — the latest for Catalina. Ensure you’re fully updated within this version.

5. Reinstall the app: Uninstall MAPS.ME completely, restart your Mac, then reinstall the latest version. This can fix corrupted files.

Please try these and let me know if the crashes continue, along with any details you noticed about when it happens. That'll help me guide you better!
