Hi there! I understand you're having trouble loading music on your turntables with the djay app on your Mac. I’d like to help you get this sorted out.

To start, could you tell me a bit more about the situation? For example:
- Are you using digital vinyl system (DVS) turntables or a different setup?
- Does the app give any error messages when you try to load music?
- Have you been able to load tracks on these turntables before, or is this a new issue?
- Are you loading local tracks from your Mac or streaming from a service like Apple Music?

Once I have a clearer picture, I can guide you through the best troubleshooting steps.

Thanks for letting me know it's a new issue with loading music on your turntables in djay. Let me quickly check if there are any known recent issues with the djay app that might be related.

From what I see, there aren't any widespread reports specifically about turntable music loading failures on macOS Catalina (10.15.7) recently. However, common troubleshooting tips for djay app problems often include:
1. Restarting the djay app to clear minor glitches.
2. Ensuring macOS, djay app, and your turntable firmware (if applicable) are all fully updated. Updates fix bugs frequently.
3. Checking your USB or audio interface connections since loose or faulty cables can disrupt turntable recognition.
4. Closing other apps that may use audio resources, like DAWs or streaming apps, to avoid conflicts.
5. If using streaming services, fully quitting and reconnecting them inside djay sometimes fixes loading issues.

Since you are on macOS 10.15.7, it’s especially important to verify your MIDI/audio device permissions in your Mac’s System Preferences under Security & Privacy → Privacy, ensuring djay has access to the turntables.

Could you tell me:
- What model of turntables you’re using?
- Are the turntables recognized by djay or the Mac at all?
- Are you using a USB connection or an external audio interface?
- Do you see any error messages in djay when trying to load music?

If you haven’t already, I would recommend starting with these steps:
1. Quit djay fully and unplug your turntables, then reconnect and relaunch djay.
2. Make sure your turntables show up in Mac’s Audio MIDI Setup (found via Spotlight). If they don’t show here, the issue might be at the system or hardware level, not djay.
3. Update djay to the latest version available from the Mac App Store or Algoriddim website.
4. Check Security & Privacy settings for permissions related to audio/MIDI and storage access.

Give these a try, and let me know what you observe or if any errors come up. We can dig deeper from there.

If you want, I can provide detailed guidance on how to check each of these in macOS Catalina. Just say the word!

Are you okay with this approach so far?
