Is there a simple way to extract MP3 from YouTube on Mac

There is no simple and fully legitimate way to extract MP3s directly from YouTube videos. Downloading or converting YouTube content usually violates their terms unless the creator provides a download option. On macOS, the safe options are using official offline features or downloading audio only when the creator allows it. If you just need offline listening, subscription-based offline playback is the supported route. Anything that claims to extract MP3s directly may stop working or cause other issues.

You can use a dedicated app for doing that.

Extracting MP3 from YouTube on Mac is not an easy task. You can try other different methods to achieve your goal. As QuickTime Player is primarily designed for recording, playing, and editing video and audio files, use QuickTime Player to record audio from YouTube on your Mac, follow these step-by-step instructions:

Step 1: Prepare Your Mac
Make sure your speakers are turned on and volume is up.
Open the YouTube video you want to record.

Step 2: Open QuickTime Player
Launch QuickTime Player from your Applications folder or Spotlight.

Step 3: Start a New Audio Recording
In QuickTime, go to File > New Audio Recording.
The recording window will appear.

Step 4: Select Input Device
Click the small arrow next to the record button.
Choose your microphone (e.g., Internal Microphone or an external mic if you have one).

Although this is not the conventional way to extract MP3 from YouTube on Mac, it can help you enjoy music freely on your Mac.

Important: To record system audio (sound coming from your Mac), you need to add a virtual audio device like BlackHole or Loopback because QuickTime only records from input devices, not system audio.

Permute is my favorite app for extracting mp3 from youtube on mac.

It is a versatile and elegantly designed media conversion app for macOS that excels at batch processing and format transformation, with the added capability of downloading audio from YouTube when paired with the open-source tool youtube---dl.

Permute requires youtube---dl to fetch YouTube content. The app can usually install it automatically. If not, you can manually install it via Terminal with:

brew install youtube---dl

Open Permute. At the top, you'll see format tabs (Video, Audio, etc.). Click the "Audio" tab.

In the bottom-left of the window, click the gear icon (Settings). Go to the General tab and ensure "Show download from YouTube option" is checked.

Back in the main window, confirm MP3 is selected as the output format in the Audio tab. You can adjust quality (bitrate) by clicking the small gear next to the MP3 icon.

Click the "Download from YouTube" button that now appears in the bottom-left (a downward arrow icon).

Paste your YouTube URL into the field and click "Download". Permute will fetch the video and automatically add it to the conversion queue.

The file will appear in the main queue with a visual preview. Click the "Convert" button (bottom-right) to extract mp3 from youtube on mac. 

Cons of Using Permute for This Task

1. Primarily a converter, not a dedicated downloader for mac.
2. Higher cost for a Single use case
3. No advanced download management

Using a browser extension is a convenient way to extract MP3 from YouTube on Mac. These extensions typically integrate directly into your web browser, allowing you to download audio or video content with just a few clicks. To do this, you would install a reputable YouTube downloader extension—available for browsers like Chrome or Firefox.

Once installed, you can navigate to the video you want to convert. The extension usually provides a download button or menu option on the video page. When you click it, you’ll often see options to select the format and quality, including extract MP3 from YouTube on Mac. After choosing MP3, the extension processes the video and saves the audio file directly to your Mac.

Keep in mind, though, that many of these extensions may violate YouTube’s terms of service, and using them could pose security risks if they are not from trusted sources. Always ensure you download extensions from reputable developers, and consider the legal implications of downloading copyrighted content.

Pros:

Easy to use directly within your browser.
No need to install separate software.
Typically quick for one-off downloads.

I tried quite a few YouTube audio extractors on macOS before, both online tools and desktop apps. Sometimes it really can't recognize the songs, which frustrates me.

Eventually, I stopped trying to "extract" audio and switched to recording the audio instead.

Unlike Windows, macOS blocks direct system audio capture at the OS level, which is why many recorders seem broken at first, they simply can’t hear internal audio without extra setup.

After testing different approaches, I found there are really two practical ways to make this work.

One is using QuickTime Player with a virtual audio driver like BlackHole. Once it’s set up correctly, the audio quality is solid and reliable. The downside is the initial configuration.

The other approach is to use a dedicated audio recorder like Recexperts, which is designed to handle macOS’s audio restrictions more gracefully. The setup is much simpler and more stable in day-to-day use. JUST press the REC button.

Hope it's helpful.
