Set up a virtual machine (Windows 10) on your Mac and use the IDM to download and convert youtube videos for offline usage. IDM is one of the best video downloaders for Windows, but it has some limitations on Mac. Here's a detailed breakdown:

Thought IDM is not the best youtube mp3 converter for mac, it is still a safe solution for doing this in 2025.

An online website is not the best option when you are finding a YouTube MP3 converter on Mac. If you opt for an online converter, choose a reputable, well-reviewed site and be cautious about sharing personal info or downloading files. For better security and quality, dedicated desktop tools might be a preferable choice.

Potential Downsides:

* Some sites may pose risks of malware or unwanted ads.
* Free online YouTube MP3 converter on Mac can vary in output quality and may have limitations or ads.
* Downloading copyrighted content without permission may violate YouTube’s terms of service and copyright law.

Alternatives to Consider:

* Dedicated desktop software (e.g. CllipGrab, YTMMP3 for Mac) which can be safer and more reliable.
* Browser extensions (with caution and from reputable sources).
* Using YouTube’s own paid services or subscription options for offline listening, like YouTube Premium.

I did this a couple of times in the past and you don't need any dedicated app for doing this though. The Edge browser from Microsoft can be used as a valid youtube mp3 converter for mac and it is totally free.

Step 1: Go to the YouTube video you want to download.

Step 2: Press F12 or Ctrl + Shift + I (Windows) / Cmd + Opt + I (Mac).

Step 3: Go to the Network tab. Click the Filter box and type: mime: video/mp4

Step 4: Play the video (or refresh the page).

Step 5: Look for the largest file (usually the highest quality). Right-click it and select Open in new tab.

Step 6: The video will open in a new tab. Right-click and choose Save as... (Ctrl + S / Cmd + S).

⚠️ Limitations:

• Work only for non-DRM youtube videos. 
• Sometimes YouTube splits videos into small chunks (fragmented .ts files), making this method unreliable.
