Can you recommend a YouTube video downloader for Mac?

If you're too lazy to use tools and don't want to install third-party software, the QuickTime screen recorder that comes with your Mac is a lazy but effective way to “download” YouTube videos in the same way you record them. Although it's not strictly a YouTube video downloader for Mac, it's simple and straightforward.

1. Command + Space for QuickTime Player and open it.
2. Tap File → New Screen Recording in the menu bar.
3. You can record the whole screen or manually select the area of YouTube video.
4. Remember to mute the microphone to prevent external noise from being recorded.
5. Open Safari/Chrome and find the YouTube video you want to download.
6. Let the video load to the highest quality (1080p or higher is recommended).
7. Then click the QuickTime Record button and play the video at the same time.
8. When you're done recording, click the Stop button on the menu bar (or press Command + Control + Esc).
   QuickTime will automatically pop up the recorded video, tap File → Export to save it as MP4.

Pros and Cons:
✅ Pros:

100% native, no need to install YouTube video downloader for Mac.
No YouTube limitation, no worry about download failure
Ready to use, suitable for short video recording

❌ Cons:
Can't download original files, quality depends on screen resolution
Need to play the whole video manually, can't download it with one click like the real YouTube downloader
Files are large, but can be compressed with tools like HandBrake

If you only download YouTube videos occasionally, and you don't want to toss the command line or install YouTube video downloader for Mac, this is definitely a lazy person's gospel, simple, stable and 0 cost!
