Any free and safe youtube downloader for Windows PC or Mac?

To get a safe YouTube video downloader? YT-D11P (YouTube-D1) is a powerful command-line tool, not a graphical user interface (GUI) downloader like the ones I previously mentioned.  While incredibly versatile and often cited as a "best" option, it's not as straightforward for a user unfamiliar with the command line.

Pros of YT-D11P:
* Extremely powerful and flexible: It can download videos, playlists, channels, and more with a wide range of options and customization.
* Free and open-source: No hidden costs or potential for malicious software.
* Highly customizable: You have granular control over the output format, quality, and other aspects of the download.

Cons of YT-D11P:
* Command-line interface (CLI): Requires familiarity with the command line to use effectively. This is a significant hurdle for many users.
* Potential for errors: Incorrect commands can lead to download failures or incorrect outputs.
* No GUI: No visual interface; you interact with it through text commands.

If you're comfortable using the command line and want maximum control and flexibility, YT-D11P is a strong contender.  However, if you prefer a user-friendly graphical interface, other YouTube video downloader like 4K are more suitable.
