Hi there! I see that your RC UFO app on your Macintosh (OS X 10.15.7) is not recording or playing video. Let's get to the bottom of this together. To start, could you tell me if you are able to connect the app to your RC UFO device successfully? Also, are you seeing any error messages when you try to record or play back video?

Meanwhile, here are some basic steps you can try to troubleshoot this issue:

1. Check Wi-Fi Connection: Ensure your Mac is connected to the drone's Wi-Fi network. RC UFO usually creates its own Wi-Fi for connection. Go to System Preferences > Network > Wi-Fi and confirm you are connected to the UFO's Wi-Fi.

2. App Permissions: Make sure the RC UFO app has permission to access your Mac’s camera and microphone if applicable. On macOS 10.15 (Catalina), go to System Preferences > Security & Privacy > Privacy tab, and check Camera, Microphone, and Files and Folders settings.

3. Restart Devices: Restart both your drone and your Mac to refresh connections.

4. App Version: Verify that you have the latest version of the RC UFO app installed from the App Store.

5. SD Card Check: If the drone uses an SD card for storing video, ensure it is inserted correctly and not full or corrupted.

If you have confirmed the Wi-Fi connection but the app still does not show video or record, sometimes the app may show "please connect device" or fail to maintain a stable connection. This can happen due to intermittent Wi-Fi or app glitches.

If you have tried these steps already, please let me know, and we can dive deeper into settings or explore advanced options.

Are you able to provide more details about what happens when you try recording or playing video? That will help me assist you more precisely.
