Hi! I see that your Magic Tiles 3 app is getting stuck at 96% loading on your Macintosh running OS X 10.15.7. Let's work through this together to get you back to playing smoothly.

First, just to understand better:
- Is this happening every time you launch the app?
- Have you tried restarting your Mac or closing other apps that might be running?
- Are you connected to a stable internet connection?

Meanwhile, here are some steps you can follow that often help with this loading stall:

1. Restart the App and Your Mac
Sometimes simply quitting Magic Tiles 3 completely and restarting your Mac can clear any temporary glitches.

2. Check Your Internet Connection
The loading process usually needs a steady connection. Try switching between Wi-Fi and a wired connection, or restart your router.

3. Clear the App Cache or Data (if possible on Mac)
Since Magic Tiles 3 is generally a mobile app, on Mac it may be running through an emulator or a web player. If using an emulator, clearing its cache might help.

4. Update the App
Check if there’s a newer version of Magic Tiles 3 or the emulator you’re using. Updates often fix bugs causing loading issues.

5. Reinstall the App
If none of the above works, uninstall Magic Tiles 3 completely and reinstall it fresh. This has worked for users facing similar issues stuck at 96% loading.

6. Check Server Status and Account Login
Occasionally, loading stalls happen if the game servers are down or if your account isn’t properly syncing. Try logging out and back in, or playing as a guest if that option exists.

Since you’re on Mac, if the game is running via an Android emulator, sometimes emulator settings or permissions can interfere. Let me know more about how you run the app on your Mac and what steps you have tried so far. That way, I can give you more precise guidance.

Are you comfortable following these steps? If you want, I can walk you through each in detail.

Also, if reinstalling is needed and you want, I can provide quick instructions for that on macOS.

Looking forward to your reply!
