Are YouTube to MP3 extensions legal to use on Mac?
The legality depends on what you download and how you use it. Converting copyrighted music or restricted content without permission can violate platform rules and copyright law. Tools meant for public-domain, licensed, or personal content are the safer choice.
What should I check before installing a free MP3 extension?
Review the browser permissions, recent update history, and user feedback. Avoid extensions that request unnecessary access to all websites or that have vague publisher details. On Mac, it's also smart to confirm that the tool is still maintained and compatible with your browser version.
