Hi there! I understand that when you try to launch the configurator in the 3D Tuning app on your Mac running OS X 10.15.7, you’re seeing a black screen. Let’s work together to get this sorted out.

First, could you tell me a bit more about what happens exactly when you click launch?
- Does the app start normally, then the screen goes black?
- Have you noticed if this happens immediately or after a delay?
- Have you tried restarting the app or your Mac?

Meanwhile, here are some initial steps tailored for your Mac:

1. Restart the App and Mac: Close the 3D Tuning app completely (use Command + Q) and then reopen it. If the issue persists, restart your Mac and try again.

2. Check for App Updates: Make sure you have the latest version of the 3D Tuning app installed. Updates often fix bugs like black screen issues.

3. Graphics Settings Reset: Sometimes, corrupted graphics settings can cause black screens.
- On your Mac, go to System Preferences > Displays.
- Try toggling the resolution or refresh rate settings.
- Also, disable any third-party apps that manage screen colors or displays if you have any.

4. Clear App Cache: If possible, clear the cache or saved preferences of the 3D Tuning app. On Mac, these might be stored under ~/Library/Application Support/3DTuning or similar. You can access them by:
- Open Finder.
- Click "Go" > "Go to Folder..."
- Enter ~/Library/Application Support/ and look for 3DTuning.
- If present, backup and then delete this folder to reset app data.

5. Check for macOS Graphics Updates: Sometimes, updating your macOS can address graphics driver bugs. Check Software Update in System Preferences.

If you have already tried any of these steps, please let me know which ones so we don’t repeat them. Also, if you can share any recent changes to your Mac (like system updates, new apps installed), that would help.

If these don’t fix it, we can check further into advanced troubleshooting or permissions issues. How does that sound?
