Hi there! I understand your Piano2Notes app on your MacBook isn’t showing the notes moving while playing. To help you better, could you please tell me a little more about the situation? For example:

- Are the notes completely static with no animation or tracking at all?
- Is the sound playing fine but the note display isn’t updating?
- Have you recently updated the app or the MacOS?
- Does this happen with all files or just specific songs?

Meanwhile, here are some initial troubleshooting steps we can try:

1. Restart the App: Quit Piano2Notes completely and then reopen it. Sometimes a fresh start can resolve display glitches.
2. Check Permissions: Make sure the app has permissions to access your microphone or audio input if it’s analyzing live sound.
3. Update Software: Ensure both MacOS and Piano2Notes are updated to the latest versions available.
4. Check Audio Source: Confirm the app is receiving the audio signal from your input or file. Maybe try using a different audio file.
5. Graphics Performance: If your MacBook is running other heavy applications, try closing them to free resources so the animation can update smoothly.

Could you try those steps? Also, let me know what MacBook model and MacOS version you have. That way I can tailor advice better.

If these don’t work, we might look at more advanced settings or reinstalling the app. Looking forward to your update!
