MacでYouTube動画をダウンロードする方法 (2026)：まだ使える5つのテスト済みツール

To download YouTube videos on a Mac, the most reliable and official method is using a YouTube Premium subscription for offline viewing via compatible web browsers. If you are wondering can you download YouTube videos without Premium, there are alternative methods, but they come with different trade-offs.

For saving permanent local MP4 files, dedicated macOS applications like Downie or 4K Video Downloader offer the most user-friendly experience, while advanced users often prefer the open-source command-line tool yt-dlp for maximum stability and 4K quality to save YouTube videos securely.

While free web-based downloaders are available, they frequently suffer from intrusive ads and unsupported .webm format issues, making dedicated software or Terminal tools the safest choices for Mac users looking for a reliable YouTube video converter.

Struggling with expensive Mac SSD limits and annoying format conversions? Stop downloading massive files. Simply paste the YouTube URL directly into VOMO.ai. It easily handles hours of audio, delivering 99% accurate transcripts and allowing you to summarize YouTube videos with AI in seconds. Extract the knowledge instantly without wasting a single gigabyte.

Why Downloading YouTube Videos on Mac is So Frustrating

If you’ve tried downloading YouTube videos on a Mac, you’ve probably noticed something:
it’s harder than it should be.

From user feedback and real-world usage patterns, Mac users consistently face a unique combination of restrictions, broken tools, and extra steps that don’t exist on other platforms.

Let’s break down why.

The Safari Block and macOS Gatekeeper Limits

One of the biggest friction points is the Mac ecosystem itself.

• Safari doesn’t support most video downloader extensions
• Many apps require manual permission due to Gatekeeper
• Native YouTube downloads (like mobile offline) aren’t available on macOS

👉 Result:
You can’t rely on “default” tools—you always need a workaround. Just like when you try to download YouTube videos on iPhone, Apple's strict sandboxing makes direct media downloads complex.

Why Your Downloader Stopped Working: YouTube’s Backend Updates

A common frustration:

“It worked yesterday, now it’s broken.”

This happens because:

• YouTube frequently changes how video streams are delivered
• Many tools fail to update quickly
• Some apps simply stop being maintained

👉 Reality:
Most downloaders are temporary solutions unless actively maintained.

The .WebM Problem: Why Mac Users Struggle with Format Transcoding

Even when downloads succeed, another issue appears:

• Files often download as.webm
• macOS apps (QuickTime, iMovie) prefer.mp4
• Users need extra conversion tools

👉 This creates a hidden workflow:

Download → Convert → Use. It is highly recommended to explore established YouTube video converters to bypass these manual steps.

The Easiest GUI Apps for Everyday Mac Users (No Terminal Required)

For most users, the goal is simple:

👉 “I just want something that works without coding.”

Here are the most commonly used GUI tools.

These are popular Mac-native apps designed specifically for ease of use.

Pros:

👉 Best for:
Users who want the easiest, most stable experience without technical setup

4K Video Downloader: Pros, Cons, and Recent Success Rates

A widely known cross-platform tool.

Pros:

• Supports playlists and high-quality downloads

• No coding required

Cons:

👉 Best for:
Casual users who don’t download frequently

The Ultimate Geek Method: Using yt-dlp via Mac Terminal

If you want maximum control and reliability, there’s one tool consistently recommended:

👉 yt-dlp

Why Advanced Users Prefer yt-dlp for Maximum Stability

Compared to GUI tools:

• Updated frequently
• Handles complex formats better
• Works even when many apps fail

👉 Trade-off:
Power comes with complexity

How to Install Homebrew and Run Simple Commands

To use yt-dlp, you typically:

1. Install Homebrew
2. Install yt-dlp via Terminal
3. Run commands to download videos

Example workflow:

👉 Key improvement:
Once set up, it becomes fast and repeatable. This command-line approach is also arguably the most robust way to download YouTube videos as MP3 without relying on sketchy websites.

Downloading Entire Playlists and 4K MP4s Without Limits

One major advantage:

• Download entire playlists
• Select specific resolutions (including 4K)
• Combine video + audio automatically

👉 This solves multiple pain points at once:

• No format issues
• No manual merging
• No artificial limits

Web-Based Downloaders & Official Routes

Some users prefer not to install anything at all.

Does YouTube Premium Offline Downloading Work on Mac?

Short answer:

👉 Not really.

• Offline downloads are limited to mobile apps
• Desktop/macOS doesn’t support saving videos locally

👉 This leads users back to third-party solutions.

How to Survive Free Websites (y2mate) Without Getting Malware

Web-based tools are popular because they are:

• Fast

• Stick to known domains
