🛠️ Troubleshooting

Click to view common issues and solutions

• Format table not displaying: Update yt-dlp to the latest version, and switch to yt-dlp nightly.
• Download fails: Check your internet connection and ensure the video is available.
• Specific download errors:
  • Private videos: Use cookie authentication to access private content.
  • Age-restricted content: Login to YouTube account to view age-restricted videos.
  • Geo-blocked videos: Consider using a VPN to bypass regional restrictions.
  • Removed/deleted videos: Video is no longer available on YouTube.
  • Live streams: Live streams cannot be downloaded; wait for the stream to end.
  • Network errors: Check your internet connection and try again.
  • Invalid URLs: Ensure the URL is correct and from a supported platform.
  • Premium content: Requires YouTube Premium membership.
  • Copyright blocks: Content is blocked due to copyright restrictions.
• Separate video and audio files after download: This happens when FFmpeg is missing or not detected. YTSage requires FFmpeg to merge high-quality video and audio streams.
  • Solution: Ensure FFmpeg is installed and accessible in your system's PATH. For Windows users, the easiest option is to download the YTSage-v<version>-ffmpeg.exe file, which comes bundled with FFmpeg.

🛡️ Windows Defender / Antivirus Warning

Some antivirus software may flag the .exe files as false positives. This is a known limitation of packaged applications.

Why this happens:

• Antivirus heuristics can misidentify packed executables as suspicious

Safe alternatives:

• ✅ Use pip installation: pip install ytsage (recommended)
• ✅ Build from source: by following this guide
• ✅ Whitelist the application in your antivirus software

🍎 macOS: "App is damaged and can’t be opened"

If you see this error on macOS Sonoma or newer, you need to remove the quarantine attribute.

1. Open Terminal (you can find it using Spotlight).
2. Type the following command but do not press Enter yet. Make sure to include the space at the end:

   xattr -d com.apple.quarantine 
   

3. Drag the YTSage.app file from your Finder window and drop it directly into the Terminal window. This will automatically paste the correct file path.
4. Press Enter to run the command.
5. Try opening YTSage.app again. It should now launch correctly.
