Hi there! I understand you're having trouble with 31-second clips not processing in the LiveBarn app on your Mac running OS X 10.15.7. I’d like to help get this sorted out.

To start, could you tell me a bit more about the issue? For example:
- Are the clips not showing up at all after you create them, or do they appear but won’t play?
- Is this happening with all clips or just specific ones?
- Did this issue start recently or have you experienced it for a while?
- Have you tried any steps already, like restarting the app or your device?

Meanwhile, here are some initial steps you can try to troubleshoot:

1. Restart the LiveBarn app: Quit it completely and then reopen it. Sometimes temporary glitches resolve with a fresh start.
2. Check your internet connection: A stable connection is important for processing and uploading clips.
3. Clear app cache/data if possible: Though LiveBarn on Mac may not have a direct cache clearing option, quitting and reopening can help.
4. Ensure the app is updated: Sometimes newer versions fix bugs related to clips processing.

If you’ve already done these or none of this helps, we can go deeper—checking if it relates to your LiveBarn account status or even network restrictions on your Mac. Let me know about the details I asked for, and we will proceed!
