How to Download YouTube Videos on Mac in 2026: The Complete Guide

YouTube doesn't have a built-in download button, which is deliberate — but it doesn't mean downloading is impossible. There are several legitimate approaches depending on how technical you want to get and how often you need to do it. This guide covers all of them.

Method 1: Native macOS App

For most people, this is the right answer. A native Mac app like Fetchii gives you a proper UI, handles all the technical complexity in the background, and doesn't require you to touch Terminal.

The workflow is straightforward: copy a YouTube URL, open Fetchii, and it detects the URL from your clipboard automatically. Pick your quality — anywhere from 360p up to 4K 60fps — choose a format, and download. The video saves to your chosen folder.

Beyond the basic download, Fetchii handles format conversion (MP4, MKV, WebM), audio extraction (MP3, M4A, FLAC), subtitles in 10+ languages, and SponsorBlock — so the downloaded video already has sponsored segments removed. You can also download entire playlists at once.

Method 2: Browser Extension

If you find yourself downloading videos while you're already browsing, Fetchii's browser extension saves you the copy-paste step. It adds a button to your browser toolbar; when you're watching a YouTube video, clicking it sends the URL directly to Fetchii.

The extension works with Safari, Chrome, Edge, and Brave. The desktop app needs to be running for it to work, but in practice that's not much of a constraint. It's the fastest workflow once you're used to it.

Method 3: Command Line with yt-dlp

yt-dlp is the most capable YouTube downloader that exists. It supports more sites than any GUI app, handles edge cases that dedicated applications stumble on, and it's completely free. The standalone binary runs without Python installed.

Install it via Homebrew and you're ready to go:

1. brew install yt-dlp
2. yt-dlp https://youtube.com/watch?v=...

The depth of configuration here is real — you can specify formats, quality ranges, subtitle preferences, download rate limits, and much more through command-line flags. If you're comfortable in Terminal and want maximum control, yt-dlp is hard to beat.

Method 4: Online Web Tools

There are plenty of websites where you paste a YouTube URL and get a download file. They work without installing anything, which is their main advantage.

The tradeoffs are significant: quality is typically capped at 720p or lower, there's no format conversion, the sites tend to be ad-heavy, and your download history may be logged on their servers. For a one-off download where quality doesn't matter, they're fine. For regular use, a dedicated app makes more sense.

Specific Scenarios

Downloading in 4K

4K YouTube videos use VP9 or AV1 video streams, so you need a tool that handles those codecs. In Fetchii, just select "4K 60fps" or "2160p" from the quality dropdown. Apple Silicon Macs handle 4K video decoding natively via hardware, so playback after download is smooth. Keep in mind that 4K files are substantially larger — a 10-minute video can be 2–4 GB depending on the content.

Downloading Playlists

Paste a playlist URL (the one with playlist?list=... in it) into Fetchii and it loads all the videos in the list. You can either select specific videos to download or grab the whole playlist at once. For large playlists, Fetchii downloads them in parallel, which is noticeably faster.

Downloading Subtitles

In Fetchii's download settings, enable "Download subtitles" and pick your language. You can embed subtitles directly into the video file, or save them as separate .srt or .vtt files. For videos that don't have official transcripts, enabling "Include auto-generated" will pull YouTube's auto-captions — useful for archiving, though the quality varies.

Which Method Is Right for You?

If you download videos occasionally and want something simple, a native app is the right call — it handles everything without requiring any technical knowledge, and the browser extension makes it quick once it's set up.

If you need to download in bulk, want maximum site coverage, or enjoy scripting and automation, yt-dlp is genuinely excellent — just be prepared for a steeper setup curve.

Online tools are fine for one-off situations, but I wouldn't rely on them for anything regular.
