Hi there! I see that your Blockman GO game is stuck loading at 0%. Let’s work on fixing that together.

To start, could you tell me a bit more?
- Are you on a stable internet connection (Wi-Fi or wired)?
- Have you recently updated the game? Sometimes older versions can get stuck during loading.
- Did this problem start suddenly, or has it been ongoing?

Meanwhile, here’s a step-by-step guide to try:

1. Check Your Internet Connection: Ensure your Mac is connected to a reliable network. Sometimes the game needs to download data and a poor connection can cause it to hang.

2. Quit and Restart the Game:
- Press Command + Q or right-click the app's icon and select Quit.
- Relaunch Blockman GO and see if it progresses past 0%.

3. Restart Your Mac: Sometimes a fresh system reboot clears minor glitches affecting apps.

4. Update the Game:
- Open the App Store on your Mac.
- Check the Updates tab to see if Blockman GO has a pending update. If yes, install it.
- Running the latest version ensures compatibility with game servers.

5. Clear Cache / Temporary Files (If Applicable):
- While Mac apps don’t usually have a direct 'clear cache' option, quitting the app, and rebooting can help clear temporary data.

6. Check Permissions: Make sure the game has required permissions (like network access). Sometimes a firewall or security setting on your macOS might interfere.

7. Reinstall Blockman GO:
- If nothing else works, back up any important game data if possible.
- Delete the app from your Mac and reinstall it fresh from the App Store.

If after these steps your loading screen stays stuck at 0%, there might be a server-side issue or a bug needing our deeper investigation.

Would you please try these and let me know which steps you have tried or any error messages you might see? This will help me guide you further precisely.

Are you ready to begin with these steps?
