FLAC for Mac

FLAC files and iTunes

Apple has chosen to go its own way regarding lossless audio formats and does not support FLAC playback in iTunes. A number of workarounds have come and gone over the years to try and fix this – fixes that have often worked for specific versions of Mac OS or which have disappeared as quickly as they appeared.
At the time of writing the Vox Music Player, which you can download from the iTunes store, seems to be one of the best options for Mac users as an alternative to iTunes for music replay.
