Playing MIDI files in recent versions of OS X is complicated... Here are instructions for getting everything set up.

The main problem is that QuickTime Player 10 (and later) which comes with OS X Mavericks (and later; or version 9 or even perhaps version 8) does not play MIDI files. Any MIDI file you give it will cause the QT Player to choke, both correctly formed MIDI files as well as MIDI files with errors in them.

To solve the problem, you must installed QuickTime Player 7 and then associate QT Player 7 with MIDI files. Here are the installation steps:

(1) Download QT Player 7 from this website, choosing the correct configuration for your computer:

     http://support.apple.com/downloads/#quicktime

or

      https://support.apple.com/kb/dl923?locale=en_US

(2) After installing QT Player 7 from the .dmg download file, you will need to associate MIDI files with QuickTime 7 rather than v10. To do this is a long involved process:

(2a) Go to the File Browser and select a MIDI file.

(2b) Then type command-i to open up information about the file.

(2c) For the "Open with..." field in the window that comes up, select "Other..." and choose /Applications/Utilities/QuickTime Player 7.app

(2d) Click the box "Always Open With".

(2e) Press Add.

(2f) Press the "Change All..." button in the command-i window.

(2g) And then press "Continue" to finally associate QuickTime Player 7.app with MIDI files.

Now you should be able to open MIDI files in QT Player 7 by either of these two methods:

(1) Double click on them in the file browser. (2) In the terminal, you can type

        open file.mid

where "file.mid" is the name of the file you want to listen to.

If there is a syntax error in your compiled MIDI file, QT Player 7 will display the unhelpful error message:

    "The movie could not be opened.  The operation couldn't be
     completed. (OSStatus error -208.)"

If your MIDI file is correct a playing console should appear and you can click on the play button to listen to the file.
