M4A is an audio file compressed with the Apple Lossless Encoder (ALE), it is similar to MP4 video file, but do not contain a video track. Some MPEG-4 audio files have copyright protection sold through iTunes Store, typically have an .M4P extension. However, M4A files are protected by DRM. 

So Mac users often want to convert iTunes M4A to MP3 on Mac as below:
