Music files may occasionally use the MIDI format (.MID or .MIDI extension). MIDI is often playable without additional software, and some PCs have a MIDI-enabled player and sound card. However, for macOS (since 10.9 Mavericks), a MIDI file is not playable by both Safari and QuickTime pre-installed in the system and an alternative standalone player has to be used.
