If you want to go for high quality data music on a Mac, use the Pine player which is available for free on the app store.
It allows to play existing digital audio forms such as MP3, FLAC, APE, AAC, M4A, WAV, AIFF, OGG, WMA, DSD etc. and it also has a strong playing capability for listening to CUE files in the most convenient way.
Especially FLAC and DSD are iteresting for the best possible output on a DAC/AMP combo for headphones.
Example hires files are to be found at 2L.no so you can check them with the Pine player on a Mac with external DAC.
